Hi all. I am trying to port TFM using the corstone1000 platform. Previously, I was using the 1.7.0 version. TFM version was recently updated and I am trying to use the 1.8.0 version by downloading it from the site below. https://git.trustedfirmware.org/TF-M/trusted-firmware-m.git As instructed by the site below ( https://tf-m-user-guide.trustedfirmware.org/platform/arm/corstone1000/readm… ) I executed the command below. cmake -B build/ -S . -DCMAKE_BUILD_TYPE=Debug -DTFM_TOOLCHAIN_FILE=<tf-m-root>/toolchain_GNUARM. cmake -DTFM_PLATFORM=arm/corstone1000 -DTEST_NS=OFF -DTEST_S=ON -DTEST_S_PS=OFF -DTEST_S_PLATFORM=OFF -DEXTRA_S_TEST_SUITE_PATH=platform/ext/target/arm/corstone1000/ci_regression_tests/ However, I got a cmake error as shown below. - Build type: Debug -- Host: Linux/x86_64 -- Target: Generic/arm -- Machine: template -- Host: Linux/x86_64 -- Target: Generic/arm -- Machine: template -- C_FLAGS : -mcpu=cortex-m0plus -Wall -Wextra CMake Error at platform/ext/target/arm/corstone1000/CMakeLists.txt:144 (target_sources): Cannot specify sources for target "platform_bl1" which is not built by this project. CMake Error at platform/ext/target/arm/corstone1000/CMakeLists.txt:168 (target_compile_definitions): Cannot specify compile definitions for target "platform_bl1" which is not built by this project. CMake Error at platform/ext/target/arm/corstone1000/CMakeLists.txt:175 (target_include_directories): Cannot specify include directories for target "platform_bl1_interface" which is not built by this project. I think this is caused by the target for platform_bl1 not being specified, but I don't know how to fix it. I executed cmake using the same configuration as set in corstone1000's config.cmake. Can anyone tell me why I am getting the above error? Any advice would be very helpful. thanks you.

Using bitwise or (|) / and (&) in Clang scatter file

by Bohdan.Hunko＠infineon.com

Hi For our platform we use some ,across which should set/clear bit 28 of an address (see code below). We do this for convenience reasons. #define IFX_S_ADDRESS_ALIAS(x) ((x) | 0x10000000) #define IFX_NS_ADDRESS_ALIAS(x) ((x) & ~0x10000000) Those macros are used in declaration of S_CODE_START macro. When expended in linker script (tfm_isolation_l3.o), the declaration of LR_CODE section looks as follows: LR_CODE (0x24000000 | 0x10000000) (0x4B000) { This code results in following error: tfm_isolation_l3.o", line 46 (column 21): Error: L6292E: Ignoring unknown attribute '|' specified for region LR_CODE. I tried experimenting with this and found out that when | is changed to or (see following code) then linker works fine: LR_CODE (0x24000000 or 0x10000000) (0x4B000) { Same problem is present when using bitwise and (&). But when using bitwise NOT (~0x...) everything works fine. Having to define our macros in different way brings some problems for our platform, so maybe someone knows how to solve this problem? Maybe there are compilation flags or something like that? Ideally we want | and & to work fine in linker script. Thanks!

Trying to debug TF-M across NS/S boundary

by Lena Boeckmann

Hi! I found the e-mail below from 2020 and this is exactly where I'm at right now: I have a Zephyr application with TF-M flashed on an nrf9160dk and managed to open a debugging session following the explanation here: https://tf-m-user-guide.trustedfirmware.org/platform/nxp/lpcxpresso55s69/RE… (might be good to mention in the documentation that this also works on other platforms or have a general "Debug with GDB section"). So far I can either debug the secure image or or the non-secure image, but I would actually like to see the communication between the two. Is it even possible to debug across the boundary? I'm not very experienced in using GDB (except for the basics). Is there some kind of TF-M specific tutorial or explanation by now? Or is there anyone who can give me a hint on how to do this? Kind regards, Lena Kevin Townsend wrote: > Hi Anton, > One particular difficulty I've encountered working with TF-M for the Zephyr > certification demo app, and with the LPC55S69 port to upstream TF-M is the > debugging experience with GDB and the dual execution environments.

Branch release/1.7.x to be deleted

by Anton Komlev

Hi, I plan to delete the branch release/1.7.x at the end of this week (after May 26) following TF-M release process<https://tf-m-user-guide.trustedfirmware.org/releases/release_process.html#r…>. Please let me know if someone is dependent on it and needs more time to detach from it. Thanks, Anton

psa_call performance

by Quach, Brian

Hi, Using isolation level 1 and IPC secure partition, I noticed psa_call() overhead for TFM v1.7 is significantly worse for than v1.1. Is this expected? Assuming 1 invec and 0 outvec for the PSA call.... TF-M version Psa_call() round trip cycles v1.1 4038 v1.7 6051 Regards, Brian Quach SimpleLink MCU Texas Instruments Inc.

Querying Anyone Using Shared Memory to Share Lifecycle, Bootseed, Hardwareversion Info

by Sherry Zhang

Hi, Currently in the Attestation partition, when encoding the security lifecycle, boot seed, and hardware version claims, these info are searched in the shared memory firstly before calling the platform hal APIs. See the code here<https://git.trustedfirmware.org/TF-M/trusted-firmware-m.git/tree/secure_fw/…>. Sharing this information via shared memory is a legacy mechanism and MCUboot does not writes that information when booting. And calling the platform hal APIs way is recommended. I created this patch<https://review.trustedfirmware.org/c/TF-M/trusted-firmware-m/+/21021> removes looking for the security lifecycle, boot seed, and hardware version from shared memory. Before opening this patch for review, I would like to query whether this mechanism is being used by any platform. Is there any platform(which suppose runs a bootloader which is not MCUboot) using this sharing memory mechanism to provide the security lifecycle, boot seed, and hardware version information now? Thanks, Regards, Sherry Zhang

How to solve the link error while enable both mbedTLS and TF-M crypto interfaces in NSPE

by Edward Yang

Hi experts, Recently we're developing an example demo based on TF-M, the application scenario is simplified as below. MbedTLS module in NSPE is used to guarantee the secure communication with AWS cloud, while TF-M in SPE provides data encryption/decryption and sensitive data storage services. So both TF-M interfaces and mbedtls module are enabled on NSPE, there will be two implementations of PSA Crypto and this will result in a link error. The red box displays files with conflicts between mbedtls and TF-M, which prevent the project from compiling. Can all TF-M code be converted into a lib to avoid linking issues? Or is there any other way to solve this problem? Best Regards, Poppy Wu http://www.mxic.com.cn
