Bool cast is wrong in Corestone cmake file

by Bohdan.Hunko＠infineon.com

Hi, Seems like following code $<$<BOOL:TFM_PARTITION_PLATFORM>:${CMAKE_CURRENT_SOURCE_DIR}/services/src/tfm_platform_system.c> In platform/ext/target/arm/corstone1000/CMakeLists.txt is wrong because it uses TFM_PARTITION_PLATFORM but should use ${ TFM_PARTITION_PLATFORM } If so then maybe platform maintainers can fix this.

Recommended GNU compiler version

by Quach, Brian

Is 11.2-2022.02 the recommended compiler version? I saw TF-M v1.8 states: " GNU Arm compiler version *10-2020-q4-major* has an issue in CMSE support. The bug is reported in `here <https://gcc.gnu.org/bugzilla/show_bug.cgi?id=99157>`__. Select other GNU Arm compiler versions instead. GNU Arm compiler version greater and equal than *11.3.Rel1* has a linker issue in syscall. Select other GNU Arm compiler versions instead. " Regards, Brian Quach SimpleLink MCU Texas Instruments Inc.

gateway attribute question

by Quach, Brian

Hi, When is it appropriate to use "__tz_c_veneer" vs. "__tfm_nspm_secure_gateway_attributes__"? The only difference appears to be placing it in "SFN" section. Regards, Brian Quach SimpleLink MCU Texas Instruments Inc.

Build error with customized mbedcrypto configuration

by S Krishnan, Archanaa

Hello, I am trying to build TF-M v1.8 with a custom tfm_mbedcrypto_config_profile_medium.h . I mainly do not want to use a platform specific calloc /free calls, instead use standard free() and calloc(). If I disable MBEDTLS_PLATFORM_MEMORY and MBEDTLS_PLATFORM_C in tfm_mbedcrypto_config_profile_medium.h and attempt to build TF-M, I get the following error: /arm-none-eabi/lib/thumb/v8-m.main+fp/hard/libnosys.a(sbrk.o): in function `_sbrk': /data/jenkins/workspace/GNU-toolchain/arm-11/src/newlib-cygwin/libgloss/libnosys/sbrk.c:21: undefined reference to `end' I'm able to build mbedtls package with both MBEDTLS_PLATFORM_MEMORY and MBEDTLS_PLATFORM_C disabled without any errors, the undefined reference error is only seen when building TF-M. Any thoughts on how to resolve this? Regards, Archanaa

Dependency on generated files is broken

by Bohdan.Hunko＠infineon.com

Hi all, Seems like dependency on generated files is broken. Steps to reproduce: 1. Build any platform at any mode 2. Change any .template file 3. Expected result: 1. New file is generated from the updated .template file Actual result: 1. Generated files step is skipped. My best guess will be that 1ce59292a47b1316e5d8b4d28bcaf9d8e2bdc0a5 broke it. Could this be fixed? Regards, Bohdan Hunko Cypress Semiconductor Ukraine Engineer CSUKR CSS ICW SW FW Mobile: +38099 50 19 714 Bohdan.Hunko(a)infineon.com<mailto:Bohdan.Hunko@infineon.com>

Rename TF-M branches master -> main

by Anton Komlev

Hello, Some time ago we planned to rename our master branch to main in all 6 repositories. There are multiple ways of doing that and I want to discuss with the community the best way suitable for all. I can see the following options: 1. rename master->main and use the main from one day. 2. Create the main for contribution with main->master sync. Make master R/O and delete it in 3 months. 3. Keep contributing to the master but syncing master->main. 4. Other way? I suggest option 2 but looking for better alternatives if any. Thanks, Anton

Mailbox agent API doc update - should be the final round

by Ken Liu

Hi everyone, The mailbox ns agent update document has the latest update to solidarize the API, here is the link for your review: Docs: Mailbox non-secure vectors processing (Ie4ec599c) * Gerrit Code Review (trustedfirmware.org)<https://review.trustedfirmware.org/c/TF-M/trusted-firmware-m/+/22282> The agent-specific API should be good enough for now to handle different mailbox implementation cases, such as memory-based or non-memory-based. * Non-secure provided vectors can be referenced directly to avoid extra copy. * For non-memory-based schemes, the vectors have to be collected locally in NS Agent. We are also updating the code to validate the new API, may touch those platforms that are mailbox-related, please take care of the patches as well. SPM: Update the agent API to follow the design (I38e67578) * Gerrit Code Review (trustedfirmware.org)<https://review.trustedfirmware.org/c/TF-M/trusted-firmware-m/+/22608/2> BR /Ken

New TrustedFirmware Discord Server

by Don Harbin

Hi All, Note you may have received another instance of this note but when I attempted to send to all TF ML's simultaneously it seemed to fail, so sending to each one at a time. Sorry about that. :/ We've created a Discord Server for real time chats/sharing. This solution comes at no cost to the project, is set up with channels for each project, includes a #general channel, and supports direct 1-1 chats between members, all with the goal of improving collaboration between trustedfirmware.org developers. We encourage all to join! :) Instructions for joining can be found on the TF.org FAQ page <https://www.trustedfirmware.org/faq/>. See you all there and please don't hesitate to reach out if you have any questions! Don Harbin TrustedFirmware Community Manager don.harbin(a)linaro.org
