- TF-M - lists.trustedfirmware.org

by Jaun, Mario

Hello We are interested in integrating TF-M into a project which is based on a STM32U3 MCU. The documentation states under limitations "TF-M Supported without BL1/BL2". Are there technical reasons that BL2 is not supported? If no, is support planned to be implemented in the near future? If no, would you be open for contributions regarding adding BL2 support? Thanks for your response. Best Mario

Re: no ATU setting in RDV3r1 with TF-M v2.3.0

by 김륜현

Hi Nick First, i share that i'm reviewing TF-M v2.3.0 with tag https://review.trustedfirmware.org/plugins/gitiles/TF-M/trusted-fi… In the shared commit, platform/ext/target/arm/rse/neoverse_rd/rdv3/bl2/boot_hal_bl2.c call atu_rse_drv_init() in boot_platform_post_init() like below. int32_t boot_platform_post_init(void) {     int32_t result;     enum atu_error_t atu_err;     result = rse_sam_init(RSE_SAM_INIT_SETUP_FULL);     if (result != 0) {         return result;     }     atu_err = atu_rse_drv_init(&ATU_DEV_S, ATU_DOMAIN_ROOT, atu_regions_static, atu_stat_count);     if (atu_err != ATU_ERR_NONE) {             return result;     } But, atu_rse_drv_init don't be called in platform/ext/target/arm/rse/neoverse_rd/rdv3r1/bl2/boot_hal_bl2.c anywhere. So, i tried to find ATU setting to other sources in RDV3R1 platform, i couldn't find ATU setting to load post image. Is there any codes setting ATU for each processor region that image will be loaded?

To understand better, are you working on a branch or old commit where you see atu_rse_drv_init for RDV3R1? If so, can you please share? I'm also not very familiar with that platform so it's likely I'm missing something, though it seems that the platform_post_init sequence is different from RDV3.

Need STM32 crypto accelerator support in v2.3.0

by Michael Grand

Dear all, I have seen that hw crypto acceleration has been removed from Stm32 platform in v2.3.0. I was eagerly waiting for this new LTS version however lack of crypto acceleration support for stm32 is a no go for me. Is there a plan to add crypto acceleration support later ? Or maybe I have missed something ? Best regards, Michael Grand

TF-M 2.3 PSA arch tests build fails for CM55 core

by Bohdan.Hunko＠infineon.com

Hi all, Currently build of psa arch tests fail for CM55 core of our PSE84 platform File: api-tests/tools/cmake/compiler/{ARMCLANG,GNUARM}.cmake (same in secure-debug/). Problem: The toolchain file unconditionally adds -march=... derived from CPU_ARCH. When built inside TF-M, mcpu_features.cmake already sets -mcpu=... with extension toggles. The compiler then sees two CPU specs that disagree on extensions. Why CM33 works, CM55 doesn't: CM33: -mcpu=cortex-m33 and -march=armv8-m.main describe the same extension set → accepted. CM55: -mcpu=cortex-m55+nomve+... and -march=armv8.1-m.main disagree on MVE/FP → rejected. Fix (generic): Skip the -march block when an outer build already selects the CPU (e.g. TFM_SYSTEM_PROCESSOR defined, or CMAKE_C_FLAGS contains -mcpu=/--target=). Long-term: switch psa-arch-tests to -mcpu-based selection. We have not yet pushed PSE84 psa arch tests target, but maybe this can be check by ARM team using one of ARM CM55 based platforms (e.g. Corstone-300 (MPS3))?
