Hi, Back in March, I wrote the dual-core design document at https://developer.trustedfirmware.org/w/tf_m/design/twin-cpu/bootloader/ It was discussed on the mailing list in a thread that starts at https://lists.trustedfirmware.org/pipermail/tf-m/2019-March/000088.html Since then, TF-M has defined a process for design reviews, and it would be nice to get this design document into the docs/design directory, particularly as the implementation of the design is already in the codebase. Given that there has already been discussion on the mailing list, I've gone ahead and created a review in Gerrit: https://review.trustedfirmware.org/c/trusted-firmware-m/+/2384 I also added all the people who contributed to that thread as reviewers. Please feel free to add yourself as a reviewer. Also, comments on whether this is the right process to follow for design documentation in this transitional state would be useful. Thanks, Chris This message and any attachments may contain confidential information from Cypress or its subsidiaries.

Re: [TF-M] IPC Regressions reference platform specific resources

by Mate Toth-Pal

Hi Alan, Andrej is right about PSA certification, for that you don't need to pass the regression test suite. However for submitting a change to the upstream master branch on https://www.trustedfirmware.org/ it is a requirement to pass those tests. The peripherals defined in the tfm_peripherals_def.h files are the peripherals that are mentioned in the 'mmio_regions' node in the partition manifest yaml files. It is a requirement that a macro is defined with this name that is substituted to a pointer type value. For more details see platform\readme.rst, chapter 'platformext/target/tfm_peripherals_def.h'. The type 'tfm_spm_partition_platform_data_t' is defined by the platform implementation, so TF-M core has no knowledge about the content of an object of type 'tfm_spm_partition_platform_data_t', and doesn't use it. The pointer is only considered by it as a token, that is passed to the platform HAL functions. This means that if the platform needs to do nothing related to the peripherals in the HAL functions either because - no isolation is needed to be configured for that peripheral - the peripheral doesn't exist, and the functionality is emulated (1) it is OK to define the value of the macro to be NULL (Just as it is done in platform/ext/target/musca_a/tfm_peripherals_def.h). The TFM_PERIPHERAL_FPGA_IO is used by the core test, to access button state and to blink leds. For the Musca-A platform these functionalities are emulated in the file platform/ext/target/musca_a/plat_test.c TFM_PERIPHERAL_TIMER0 is used by the IRQ tests. The upstreamed platforms all support some kind of timer, so there is a real implementation for all the platforms. (platform/ext/target/musca_a/plat_test.c) If it is not possible to create working implementations for the interfaces in platform/include/tfm_plat_test.h, then it is possible to disable the peripheral access and irq tests, by adding the following lines to the platform cmake file: set(TFM_ENABLE_PERIPH_ACCESS_TEST Off) set(TFM_ENABLE_IRQ_TEST Off) Please note, that even in this case TFM_PERIPHERAL_FPGA_IO and TFM_PERIPHERAL_TIMER0 are still need to be defined (NULL is ok), and the plat_test interface functions also need to have at least an empty implementation.

Re: [TF-M] contributing to the TF-M project

by Summer Qin (Arm Technology China)

Hi Alan, Thanks for reporting this issue. Yes, the "Create Task" in https://developer.trustedfirmware.org/maniphest is the place you can use. Just create a task, add the tag "Trusted Firmware M" and others you can set as you want or keep them as default. And please add this task link under your commit as comments, please add the test env and result as well if you have. This part needs to be updated, and we will push a patch to fix it ASAP.

Re: [TF-M] Python script to generate tf-m dependencies in JSON format

by Gyorgy Szing

Hi, We need to keep an eye on some factors which the current prototype ignores. Some that come to my mind: 1. which component shall be the owner of sw dependency info? (Documentation, cmake, something else?). 2. how does the solution scale? (i.e. be able to handle platform specific dependencies). 3. how we handle build configuration specific dependencies? (i.e. if I don't build a service then some dependency is not needed). 4. As Minos mentioned some environment verification is already done by CMake. Is it worth to extract all dependency info (tooling + SW) into a dedicated place? /George -----Original Message----- From: TF-M <tf-m-bounces(a)lists.trustedfirmware.org> On Behalf Of Minos Galanakis via TF-M Sent: 21 October 2019 16:47 To: tf-m(a)lists.trustedfirmware.org Cc: nd <nd(a)arm.com> Subject: Re: [TF-M] Python script to generate tf-m dependencies in JSON format Hi, Making CMAKE able to output the dependencies it is expecting is the quickest path, but it is only able to resolve a subset of the requirements captured by the documenation. .<https://ci.trustedfirmware.org/job/tf-m-build-test-nightly/lastSuccessfulBu…> For example the cmake version itself, or tools like srec_cat used to produce MUSCA binaries.
