Hi Thomas, I've not met such a problem yet. Could you please give more details about the portability issues in Kconfig? In our PoC, it firstly parses the Kconfig files and then convert the output Kconfig options into CMake flags. Thus the whole process is not related to any compiler. I checked Zephyr previously. It looks like Zephyr has the similar idea as our PoC does.

Introducing a dependency on Kconfig may cause portability issues with some toolchains (IAR for instance) I am working on adding support for the IAR toolchain to Zephyr, and Kconfig is one of the issues I've run into. At least in Zephyr, the output from Kconfig is run through the C preprocessor and this causes issues with the IAR preprocessor so for now I use gcc for this step.

Re: [TF-M] Gerrit issues

by Kevin Peng

Hi, In case you meet the same issue as Thomas. There are two possible solutions from our experience. One is: * Abandon both the duplicated changes. * Change the change-ID of you patch and then submit * You end up with a whole new patch without the original histories. In this way, you lose both the change history and review history. If you are OK with that, you can quick solve the issue by yourself. Otherwise, the other solution is to contact Benjamin Copeland <ben.copeland(a)linaro.org<mailto:ben.copeland@linaro.org>> to delete one of the duplicates(usually keep the one with histories). And push your new patch set after deletion.

TF-M URLs update for code and Gerrit review

Hello TF-M code moved to the new location recently with a redirection link from the original URL - for compatibility purpose. Unfortunately, Gerrit got confused with two namespaces and several patches got messed up last week. To prevent it from happen again, the old TF-M location marked as read-only mirror.

Re: [TF-M] build error

by Gyorgy Szing

Hi, Can you please run the build with "cmake -build ./ -- install VERBOSE=1". This will show compiler command lines which could help. Based on the fact your assembler is complaining not understanding assembly instructions generated by the C compiler, I suspect your compiler is not supported. For "arm-none-eabi-cc -v" I get the following output: ....... gcc version 6.3.1 20170215 (release) [ARM/embedded-6-branch revision 245512] (GNU Tools for ARM Embedded Processors 6-2017-q1-update) (Note I removed some not so interesting lines.) As you can see, the version string includes the release name of "6-2017-q1-update". All gcc binaries built by arm shall have this. Please double check what compiler you are using. The last bullet point in the blue "notes" section here: https://ci.trustedfirmware.org/job/tf-m-build-test-nightly/lastSuccessfulBu… has the link to the download site and also names the releases you can use. /George From: TF-M <tf-m-bounces(a)lists.trustedfirmware.org> On Behalf Of Shawn Shan via TF-M Sent: 04 June 2020 10:21 To: Quach, Brian <brian(a)ti.com>; tf-m(a)lists.trustedfirmware.org Cc: nd <nd(a)arm.com> Subject: Re: [TF-M] build error Hi Brian, I would like to correct my last Email: * CMSIS_5 version should be v5.5.0. * Mbedtls is not required anymore.

Hi, There are few comments on the structure document, so let's merge the first patch as a signal. This merging does not mean it is the decided shape - the structure related comments are always open, feedback on the mailing list or the task: https://developer.trustedfirmware.org/T751 Or, to be direct, put comments on the ongoing updates to the design doc: https://review.trustedfirmware.org/c/TF-M/trusted-firmware-m/+/4415 Thanks. /Ken From: TF-M <tf-m-bounces(a)lists.trustedfirmware.org> On Behalf Of Ken Liu via TF-M Sent: Monday, June 1, 2020 2:11 PM To: tf-m(a)lists.trustedfirmware.org Cc: nd <nd(a)arm.com> Subject: [TF-M] [IMPORTANT] [SOURCE STRUCTURE] The first structure adjust patch is pushed Hi, As the first commit of 'source_structure' document is merged, here is the first patch to follow the document: https://review.trustedfirmware.org/c/TF-M/trusted-firmware-m/+/4315 The patch looks big, even it just adjusts the content inside 'secure_fw'.

Re: [TF-M] TF-M PSA key management

by Soby Mathew

Hi Brian, The struct you have mentioned is part of the implementation defined `psa_key_attributes_t` data structure. The key algorithm and policy are accessed via appropriate get/set API's (like psa_set_key_algorithm/ psa_get_key_algorithm). Hence these fields are not meant to be directly accessed by the clients but are an implementation detail of crypto Service. The only reason the 2 algorithm fields exists now is because the mbedcrypto defined the structure that way. I have a patch in flight which cleans up the client view of the psa_key_attributes_t such that only fields required by client are defined. The patch is available for review here : https://review.trustedfirmware.org/c/trusted-firmware-m/+/4217 Regarding psa_open_key() and psa_close_key(), TF-M tries to implement PSA Crypto 1.0 Beta 3 version of the spec whereas the APIs are removed in 1.0 version. Currently mbedcrypto does not support 1.0 version fully yet. Once 1.0 is supported mbedcrypto, then TF-M will also make the migrate the APIs to 1.0. This is expected to happen during Q3 timeframe. Best Regards Soby Mathew From: TF-M <tf-m-bounces(a)lists.trustedfirmware.org> On Behalf Of Quach, Brian via TF-M Sent: 02 June 2020 23:44 To: tf-m(a)lists.trustedfirmware.org Subject: [TF-M] TF-M PSA key management Hi All, I see that the PSA crypto API v1.0 spec says "This specification only defines policies that restrict keys to a single algorithm, which is consistent with both common practice and security good practice. ", but the TF-M code defines two algs in the policy struct. Which will be the path going forward? struct psa_key_policy_s { psa_key_usage_t usage; psa_algorithm_t alg; psa_algorithm_t alg2; }; I also see psa_open_key() and psa_close_key() were removed from the spec. Any plans to remove from TF-M code in the future? Regards, Brian Quach SimpleLink MCU Texas Instruments Inc. 12500 TI Blvd, MS F-4000 Dallas, TX 75243 214-479-4076

Which will be the path going forward? struct psa_key_policy_s { psa_key_usage_t usage; psa_algorithm_t alg; psa_algorithm_t alg2; }; I also see psa_open_key() and psa_close_key() were removed from the spec. Any plans to remove from TF-M code in the future? Regards, Brian Quach SimpleLink MCU Texas Instruments Inc. 12500 TI Blvd, MS F-4000 Dallas, TX 75243 214-479-4076

Re: [TF-M] DSP instructions and FPU use

by Joseph Yiu

Hi Ken, Soby, In additional to FPCCR_S.TS, You should also set FPCCR_S.CLRONRET and FPCCR_S.CLRONRETS. FPCCR_S.CLRONRET ensures that FPU register contents are cleared when return from a Secure exception to the Non-secure world, and FPCCR_S.CLRONRETS ensures that the Non-secure world cannot change the FPCCR_S.CLRONRET setting.

But if a thread uses FP the FPCA is set to 1 automatically, and if exceptions are happening the FP context stacked automatically by hardware - the secure scheduler just keep the EXC_RETURN which contains FP context and finally recover it back. Which means if you enabled hardware FP unintentional it can work, the only place a problem may occur should be the non-secure preempting secure execution case. I think the only thing we are missing now is we did not set FPCCR_S.TS = 1 since we did not realize that user would enable FP in secure world. This would cause the FP register may contain secure information while Non-secure preempting secure execution. Need to go through the settings and double-check.

Re: [TF-M] Changes required to enable Zephyr integration as External_Project

Hi, Thank you very much for the changes to the image signing script - those look like great QOL improvements. WRT Ninja and externalproject support, there is currently an ongoing effort to improve the TF-M build system by rewriting it to use more modern and streamlined cmake. I haven't tested it as an externalproject yet, but am pretty confident that it should now work "out of the box". When it gets to the stage that it can be submitted to trustedfirmware.org as a patch I'll try to reply to this so you can test that. I personally hadn't used Ninja much, but am pleasantly surprised with how fast it is. I will do my best to make sure that the new cmake also works with ninja, since support should be relatively simple.

Re: [TF-M] DSP instructions and FPU use

[IMPORTANT] [SOURCE STRUCTURE] The first structure adjust patch is pushed

by Ken Liu

Hi, As the first commit of 'source_structure' document is merged, here is the first patch to follow the document: https://review.trustedfirmware.org/c/TF-M/trusted-firmware-m/+/4315 The patch looks big, even it just adjusts the content inside 'secure_fw'. To make the related sources can pass the building, some files out of the 'secure_fw' need to be changed. The goal of merging is ASAP so that we won't block upcoming features. Please provide the feedback about potential USAGE problem you may meet. As the patch is big, it won't be applicable to make THIS patch perfect to meet all the requirements defined in the document, a series of upcoming patches would come as amending. Also if there are suggestions about the structure document, please write to the mailing list and put discussion in this task: https://developer.trustedfirmware.org/T751 The rendered structure document: https://ci.trustedfirmware.org/job/tf-m-build-test-nightly/252/artifact/bui… BR /Ken

Correction - MMIO region is not sharable between partitions

by Ken Liu

Hi, In the tech forum I mentioned a potential way of sharing MMIO regions - this is not correct. Double checked the PSA FF and it is defined explicitly in the spec page 43: "A Secure Partition always has exclusive access to an MMIO region. Secure Partitions are not allowed to share MMIO regions with other Secure Partitions and MMIO regions are not allowed to overlap." Sorry for the confusion. BR /Ken

Re: [TF-M] Pre-provisioned keys

by Tamas Ban

Hi Brian, The pre-provisioned keys are highly platform dependent. TF-M just provide an API to access them, but currently we have no standard/general solution to storing them. There was question a few weeks ago related to same topic. I just copied Shebu's past answer here: "Provisioning was added as a future roadmap item in anticipation of a PSA Provisioning Specification. The Specification (Factory or application specific) hasn't happened so far. There is no active work ongoing in TF-M around provisioning. TF-M using provisioned keys in CC-312 on MuscaB1 platform is available as an example. See details here<https://ci.trustedfirmware.org/job/tf-m-build-test-nightly/lastSuccessfulBu…> under CC312 heading. In TrustedFirmware TSC, provisioning has been a discussion topic sometime back. Search for provisioning in the minutes below. https://github.com/microbuilder/certificate_chains/blob/master/rfc_tfm.md is an RFC that Kevin prepared during those discussions for TF-M devices to use certificate chain.

Simplify the veneers of library model

by Mingyang Sun

Hi all, In the current implementation, every secure function has an associated veneer function. Therefore, there are so many veneer functions in ‘tfm_veneers.c’, which have a similar prototype. This would lead to: * Waste of the veneer and secure function size – these APIs have a similar prototype, and they have unified NS dispatcher already. * More secure functions lead to more veneers and potential re-configuration of the non-secure callable area. This patch tries to unify the service entry so that: * Similar function codes do not need to be duplicated. * Keeping almost the same performance. This is also an experiment patch to start the journey to the SFN model Andrew proposed. Let’s see the feedbacks and decide what to do in the next step. https://review.trustedfirmware.org/c/trusted-firmware-m/+/4115 Please do feedback, especially the library model users – please check what kinds of the inconvenience it brings so that we can discuss the correct shape. Here are some details in the patch: Prototype of the unified veneer function: psa_status_t tfm_sfc_call(uint32_t ctrl, psa_invec *in_vec, psa_outvec *out_vec); where: the uint32_t type parameter ‘ctrl’ is a pack of parameters - psa invec length, psa outvec length, and function identifier. [8 bits for inlen][8 bits for outlen][16 bits for function identifier] This is to avoid the condition that 5 parameters will cause re-wrapping of parameters. Time cost and code size measurement: github-tracking Use the unified veneer cost of a veneer call is 1264 cost of an interrupt is 941 veneer used 832B, region size 832B, 100% cost of a veneer call is 1274 cost of an interrupt is 941 veneer used 64B, region size 832B, 7.69% Thanks, Mingyang

[RFC] Compiler-specific configurations and architecture registers

by Summer Qin

Hi, Even the ongoing HAL design abstracts all platform-specific operations, there are still some operations that need to be performed directly in TF-M, such as architecture-related operations. These operations are common for all platforms, such as: * generic assembler code for AAPCS based context management. * assign attributes to specific functions. These operations rely on compiler and architecture much instead of the platform. So, define a CORE-specific compiler configuration header file would be a straight requirement. With these unified headers, writing the architecture-specific code would be much safer because it won't involve hardcode compiler related changes. The minimal set of mandatory architecture registers is also planned to be defined. Here send out a mail to collect for the feedbacks - is it worthy of doing this to decouple the architecture from the platform, or we can just re-use the platform provided headers? Any comments are welcome:) Best Regards, Summer

Proposal to add sub-folders to collect documents under design_documents folder

by David Hu

Hi all, I'd like to propose to add sub-folders under docs/design_documents to collect the documents on the same topic. Currently, there are already 21 documents in total under docs/design_documents and the number may grow rapidly. It can be more clear if we can organize the documents on the same topic into a dedicated sub-folder under docs/design_documents. Please help review the patch set https://review.trustedfirmware.org/q/topic:%22design-doc-subdir%22+(status:… if the proposal sound interesting. I move dual-cpu and TF-M Profiles related documents to their dedicated folder respectively in the patches. Any comment is welcome! In current patches, the html pages are still put in the same level during Sphinx build. It is because design documents are grouped by document status, instead of document hierarchy. The html pages can be further organized as well if we switch to group html according to folder structures. Best regards, Hu Ziji

[RFC] [Source Structure] Design document is availiable.

by Ken Liu

Hi, There is an upcoming source structure adjustment for TF-M. The basic idea is to make the structure simple and easy to be understood by users. The significant change would be a long term goal so no worry. In the beginning, there would be changes in core and platform to align with HAL changes. Please help to put comments on the design documents - after aligned, this document would be a user guide document to describe the source structure of TF-M. The patch is here: https://review.trustedfirmware.org/c/trusted-firmware-m/+/4112 And the issue link: https://developer.trustedfirmware.org/T751 Feel free to put any comments or ask questions. Thanks. /Ken

TF-M repository restructure

by Anton Komlev

Hello, Let me announce the changes in TF-M project repository structure. To allow project grow up in a more organized way the existing codebase will be split on multiple repositories and placed under TF-M folder. This is the similar structure as all other projects have in git.trustedfirmware.org<https://git.trustedfirmware.org>. This weekend TF-M git repository will be moved from https://git.trustedfirmware.org/trusted-firmware-m.git to https://git.trustedfirmware.org/TF-M/trusted-firmware-m.git The original URL will be supported for some time (as a link to the new one) giving time for adjustment. Current plan is to keep the redirection for 6 months but let me know please, if it makes any conflict and another depreciation period is better. Best regards, Anton Komlev

Re: [TF-M] Query on persistent keys Crypto API

by Soby Mathew

Hi Kevin > Presumably this positions the merged change request around 1.0 beta 3, just to know where we stand with the API documentation versus implementation in TF-M? Yes, you are right, the Crypto service as implemented in TF-M positions it very close to 1.0 beta 3 API specification. There is still some unimplemented functionality and some differences in error code with respect to the Beta3 specification as reported by the compliance test suite here : https://github.com/ARM-software/psa-arch-tests/blob/master/api-tests/docs/t… > Presumably this migration to ID based accesses (versus handles) is still a work in progress, with a goal of perhaps being complete for 1.1? Yes, TF-M depends on mbedcrypto to provide the necessary functionality. This is work in progress and hopefully available towards Q3 timeframe. > If I comment out the psa_open_key call, I CAN access the public key in the next function, but only because I have a reference to the handle from when we first persisted the key, but I wouldn't have that handle in the real world if I was accessing a previously created key, and it seems we can't access persisted keys via ID yet, only handles, unless I'm missing something (perhaps obvious)? Hopefully the solution suggested by Sherry is good enough for you to progress although your code will need to migrate to the API as specified in v1.0 at sometime in the future when TF-M implements the same.

Since this is a very useful feature in real world applications, I was working on a sample application in Zephyr demonstrating how it might be used during device provisioning, and I was hoping to better understand the differences between the implementation in TF-M today and the 1.0 API document, specifically around KEY IDs versus key handle based access? The 1.0 API documentation, for example, describes: psa_status_t psa_export_public_key(psa_key_id_t key, uint8_t * data, size_t data_size, size_t * data_length); But TF-M implements this add: https://git.trustedfirmware.org/trusted-firmware-m.git/tree/interface/inclu… psa_status_t psa_export_public_key(psa_key_handle_t handle, uint8_t *data, size_t data_size, size_t *data_length); Presumably this migration to ID based accesses (versus handles) is still a work in progress, with a goal of perhaps being complete for 1.1? Should I still be calling psa_open_key in the interim, for example? Some examples like the AES + PKCS#7 test case here use that: https://git.trustedfirmware.org/trusted-firmware-m.git/tree/test/suites/cry… However, when I try to use psa_open_key when working with PSA_ECC_CURVE_SECP256R1, I get an INSUFFICIENT_MEMORY error, and I'm not sure how to get the psa_key_handle_t for subsequent operations like reading the key back.

I suggestion you check whether similar case happen in your code(calling psa_open_key while the key is in open). After provisioning, call psa_close_key to close the key. Then the volatile area is freed. Then to get the key handle later, you can call the psa_open_key directly. Hope it can help you!

Query on persistent keys Crypto API

Hi, Support for generating and working with persistent keys was recently merged into TF-M in the following change request: https://review.trustedfirmware.org/c/trusted-firmware-m/+/3252/8 This corresponds to section 3.2.2 (Persistent keys) of the PSA Cryptography API 1.0 (dated 19/02/2020), although there seems to be some delay in implementing the functionality described in the API document.

Re: [TF-M] TF-M Technical Forum call - May 14

by Andrew Thoelke

Hi, Following on from the presentation and discussion on Ken's "Default Handles" proposal on 30 April, we have made some updates following the feedback and further implementation consideration. I (or Ken if he attends) can present an update on the proposal. I also mentioned last time that there is some missing context for this proposal. We are working on an update for PSA-FF-M v1.1 that will provide an enhancement of the v1.0 'IPC model' for secure services, and also a 'Secure Function model' which is similar to the 'library model' of TF-M today. The objective is a single architecture that enables secure service developers to select the framework features required for the complexity of the service; and the framework implementation to be optimised for simple systems. On Thursday, I would like to present an introduction to this PSA-FF-M v1.1 roadmap, and outline the steps that we think are required.

TFM 1.0 integration merged into upcoming Zephyr 2.3

by Kevin Townsend

Hi, Just as a FYI, TF-M 1.0 support was merged into Zephyr RTOS this week, meaning that it will be included by default in Zephyr starting with the upcoming 2.3 release. Zephyr is used on the non-secure side, and TF-M is used on the secure side, with the TF-M build happening as part of the normal Zephyr build process, meaning no knowledge of TF-M internals is required to get started. It's also worth highlighting QEMU integration with Zephyr+TF-M. Using the MPS2 AN521 target, you can run application from the command-line with QEMU, meaning that you can create test applications that use the PSA APIs with no HW required, or perform certain application tests purely in SW. As an example, the following sample was run with a clean install of Zephyr, showing QEMU output and demonstrating how to use the initial attestation, crypo and secure storage services: https://github.com/zephyrproject-rtos/zephyr/tree/master/samples/tfm_integr… $ mkdir zephyrtfm && cd zephyrtfm $ west init $ west update $ west build -p -b mps2_an521_nonsecure zephyr/samples/tfm_integration/psa_level_1/ -t run [INF] Starting bootloader [INF] Swap type: none [INF] Swap type: none [INF] Bootloader chainload address offset: 0x80000 [INF] Jumping to the first image slot [Sec Thread] Secure image initializing!

We hope this will make TF-M, and all the hard work that has gone into it, far more accessible to a wider range of people, with HW no longer being an immediate limitation to trying it out.

Remove 'INDIVIDUAL_SW_COMPONENTS' support from attestation

by Tamas Ban

Hi, I let you notify that 'INDIVIDUAL_SW_COMPONENTS' support is planned to be removed from attestation service and bootloader. What is this? * Boootloader and SPE can exchange data through shared memory. This is needed to provide the boot status info to attestation service. The boot status info is included in the SW_COMPONENT claim in the attestation token. * Until now two types of data encoding was supported during this data sharing: * All boot status data item is passed as a single TLV entry: -DATTEST_BOOT_INTERFACE=INDIVIDUAL_CLAIMS * Boot status is already encoded to CBOR format at build time. Bootloader only updates a few field in it, and pass the CBOR object to SPE. Then attestation service just include this already CBOR formatted object to the token, without the need to applying further encoding. -DATTEST_BOOT_INTERFACE=CBOR_ENCODED_CLAIMS The 'INDIVIDUAL_CLAIMS' format is marked as deprecated feature for a while in the code base. Now the plan is to remove it and rely fully on the 'CBOR_ENCODED_CLAIMS' format. The build system support for this is present in TF-M for a long, and recently it was upstream to original MCUBoot 'imgtool' script as well. Next MCUBoot release (v1.6) will contain it. If you has any objection, because your project is using the 'INDIVIDUAL_CLAIMS' format then please let us know! BR, Tamas

Re: [TF-M] LPC55S69 support merged into master

Hi Kevin, Are there any plans to add ARMCLANG as a build environment for this? If so, then I can add an IAR port as well. Going from ARMCLANG to IAR is much easier than to go from GNUARM to IAR.

Improve library model secure function entry points

by David Hu

Hi all, I uploaded a patch (https://review.trustedfirmware.org/c/trusted-firmware-m/+/4009) to simplify/improve the entry points of secure functions in Library model. In current Library model implementation, each secure function includes the same inline entry point tfm_core_partition_request(). Actually, only the NS client check is required to be inline. The duplicated entry points cost much code size. Thus this patch extracts NS client check and make it as a simple inline function tfm_core_is_ns_client(). tfm_core_partition_request() becomes a normal function called by each secure function. Some quantitative results of code size optimization (about 3KB) are shown below: Profile Small (ConfigDefaultProfileS) is based on https://review.trustedfirmware.org/q/topic:%22symmetric-attest%22+(status:o… ConfigDefault + Armclang 6.10 + Release + AN521 Code RO-data RW-data ZI-data Current impl 129778 8994 272 50108 Improved 126294 8994 272 50108 ConfigDefaultProfileS + Armclang 6.10 + Release + AN521 Code RO-data RW-data ZI-data Current impl 55886 3274 200 31664 Improved 52930 3274 200 31664 Best regards, Hu Ziji

Re: [TF-M] REGION_DECLARE macros

by Sherry Zhang

Hi Thomas, OK, the problem is caused by that the names of region related symbols that IRA compiler generate are different with those of ARMCLANG. The work around below do can solve the problem. BTW the work around seems not to be a general one. I think another way to solve the problem is adding a macro like SYMBOL_NAME_BASE(region) which is a wrapper of the REGION_NAME on different compilers.

To make this work I need to split the symbol up into its components, which is done with the REGION macros. So the symbol "Image$$ARM_LIB_STACK_MSP$$ZI$$Base" turns into "ARM_LIB_STACK_MSP$$Base", which is what we use for IAR. For ARMCLANG and GNUARM the macros generate the original symbol.

Re: [TF-M] Questions on TFM_NS_CLIENT_IDENTIFICATION

by David Wang

Hi Reinhard, Add more from user's perspective: The non-secure client id can be used to identify different "clients" from non-secure side. The example from tf-m existing secure service is the storage. Different client id can access different storage space. Therefore, the storage is "isolation" among the clients. The users can create the custom secure service and leverage different client ids (let's say non-secure client id here) to identify different non-secure "callers": * The meaning of identifying different non-secure callers depends on the user case of the secure service. For example, different storage spaces, different access permissions, etc. * In RTOS, different non-secure client ids are managed via TZ_APIs (https://www.keil.com/pack/doc/CMSIS/Core/html/group__context__trustzone__fu…) if they're enabled. * The mapping between non-secure applications and the TZ secure contexts (stand for different client ids in tfm) is managed by NS RTOS kernel. When the ns applications get updated, then the mapping should also be maintained by RTOS kernel. Hope this helps.

Re: [TF-M] Questions on TFM_NS_CLIENT_IDENTIFICATION

by Ken Liu

Hi Reinhard, My assumption on the user side: - For application developers, they don't need to care about the identification and just access secure service via API. - For non-secure OS (or, a whole system level including SPE and NSPE) developers or integrators, they can implement a mechanism to help SPM identify the different non-secure threads, then SPM can do more granular client management (access control or other policies). If the don't, then SPM take whole NSPE shares the same non-secure client id and no more granular client management. Still need the real USER to provide more information in case my assumption covers partial scenarios only.

Re: [TF-M] REGION_DECLARE macros

by Sherry Zhang

Hi Thomas, The diff below is caused by this patch https://review.trustedfirmware.org/c/trusted-firmware-m/+/3942 . REGION_NAME is used to pasting the input parameters into a string. So there should be no difference between Image$$ARM_LIB_STACK_MSP$$ZI$$Base and REGION_NAME(Image$$, ARM_LIB_STACK_MSP, $$ZI$$Base) basing on the current implementation of REGION_NAME in file platform/include/region.h So, is there a specific REGION_NAME macro implementation for IAR compiler? Or the automatically generated region related symbols are with different names in IAR compiler?
