by Sherry Zhang

Hi, Just a reminder that the MCUboot version has been upgraded to v1.9.0<https://github.com/mcu-tools/mcuboot/releases/tag/v1.9.0> in TF-M. If you are using the local MCUboot repo, then you need to update it to that version to avoid build error. Regards, Sherry Zhang

TF-M release v1.6,0 date change to April 28

by Anton Komlev

Hello, TF-M release v1.6.0 will be shifted from April 15 to April 28. The main reason is Easter holiday and expected lack of availability from community and platform owners around that date. Feature freeze will be moved to April 6th when the release branch will be created. Please update your plans accordingly. Please let me know if this change make difficulty for you and better date is possible. Thanks, Anton

Simplify TFM_PLATFORM in build system

by Jianliang Shen

Hi all, I want to simplify the flag TFM_PLATFORM in build system. TF-M now already supports two different ways to choose specific platform, for example AN521: - Absolute path: '<tf-m path>/platform/ext/target/arm/mps2/an521' - Relative path: 'arm/mps2/an21' Recently I have uploaded a [tf-m patch]<https://review.trustedfirmware.org/c/TF-M/trusted-firmware-m/+/14260> to support platform name: - Platform name: 'an521' I think it will be more convenient for developers to use: - Users don't need to remember and type the absolute or relative path, only target platform name is enough. - If the structure of certain platform is changed, the default build command of TFM_PLATFORM is same. I'd be very grateful if you can give any suggestion or enhancement for me. Thanks. Best Regards Jianliang Shen

by zhilei.wang

Dear All, I view the tf-m source code for the first time, and many of the code details can not be make clear. So .., where may I find the design documents of spm, for example: trusted-firmware-m-TF-Mv1.5.0\secure_fw\spm\cmsis_func and cmsis_psa software modules.

TF-M covertly results and configs to align our coverity environment to TF-M project CI

by Kostiantyn.Tkachov＠infineon.com

Hi colleagues! Could we get a list of MISRA/CERT-C violations that were found by tf-m Coverity CI, as example from https://ci.trustedfirmware.org/job/tf-m-coverity/lastSuccessfulBuild/ Also (if it possible), could you provide Coverity configs to help align this tool setup on our side to CI and to check all changes before any pool requests?

Problem compiling Trusted Firmware M in Linux for PSOC64

by AntonioJavier.CabreraGutierrez＠infineon.com

Hello, I am writing to you asking help because we are having problems when I try to compile the Trusted Firmware M from source code. I downloaded the code from the official repository: https://git.trustedfirmware.org/TF-M/trusted-firmware-m.git I moved to the last TAG: TF-Mv1.5.0 I am following this tutorial for PSOC64 platform https://tf-m-user-guide.trustedfirmware.org/platform/ext/target/cypress/pso… When I execute the first cmake command indicating the platform and the toolchain everything works well: cmake -DTFM_PLATFORM=cypress/psoc64 -DTFM_TOOLCHAIN_FILE=../toolchain_GNUARM.cmake .. The problems appears when I build the code using the second cmake command: cmake --build cmake_build -- -j I got this output [cid:image003.jpg@01D82A77.95B43640] /home/admin/Escritorio/trusted-firmware-m/lib/ext/t_cose/crypto_adapters/t_cose_psa_crypto.c: In function 't_cose_crypto_pub_key_verify': /home/admin/Escritorio/trusted-firmware-m/lib/ext/t_cose/crypto_adapters/t_cose_psa_crypto.c:145:5: error: conversion to non-scalar type requested 145 | verification_key_psa = (psa_key_handle_t)verification_key.k.key_handle; | ^~~~~~~~~~~~~~~~~~~~ /home/admin/Escritorio/trusted-firmware-m/lib/ext/t_cose/crypto_adapters/t_cose_psa_crypto.c: In function 't_cose_crypto_pub_key_sign': /home/admin/Escritorio/trusted-firmware-m/lib/ext/t_cose/crypto_adapters/t_cose_psa_crypto.c:194:5: error: conversion to non-scalar type requested 194 | signing_key_psa = (psa_key_handle_t)signing_key.k.key_handle; | ^~~~~~~~~~~~~~~ /home/admin/Escritorio/trusted-firmware-m/lib/ext/t_cose/crypto_adapters/t_cose_psa_crypto.c: In function 't_cose_crypto_sig_size': /home/admin/Escritorio/trusted-firmware-m/lib/ext/t_cose/crypto_adapters/t_cose_psa_crypto.c:245:5: error: conversion to non-scalar type requested 245 | signing_key_psa = (psa_key_handle_t)signing_key.k.key_handle; | ^~~~~~~~~~~~~~~ secure_fw/partitions/internal_trusted_storage/CMakeFiles/tfm_psa_rot_partition_its.dir/build.make:425: recipe for target 'secure_fw/partitions/internal_trusted_storage/CMakeFiles/tfm_psa_rot_partition_its.dir/__/__/__/lib/ext/t_cose/crypto_adapters/t_cose_psa_crypto.o' failed make[2]: *** [secure_fw/partitions/internal_trusted_storage/CMakeFiles/tfm_psa_rot_partition_its.dir/__/__/__/lib/ext/t_cose/crypto_adapters/t_cose_psa_crypto.o] Error 1 make[2]: *** Waiting for unfinished jobs....

Locking of PRIS bit in AIRCR register

by JAYLES Romain

Hi all, We are currently testing the tfm-m implementation on a STMicroelectronic chip: stm32u5 board. This stm32u5 has a special register: SYSCFG_CSLOCKR (see https://www.st.com/resource/en/reference_manual/rm0456-stm32u575585-armbase…). This register allows to lock the PRIS bit of the AIRCR register from further modification. The issue here is that, in the ST implementation, thanks to this SYSCFG_CSLOCKR, the PRIS bit of the AIRCR is locked at boot (Reset_Handler in file startup_stm32u5xx_s.c). Resulting in the function tfm_arch_set_secure_exception_priorities() not being able to set the PRIS bit of the AIRCR. This situation lead to big issues at runtime as interrupt priority of NSPE are able to pre-empt interrupt of SPE. Disabling the locking of PRIS bit solve our problem but currently we don't see a clean way to integrate chip specific security features (something like callback/tfm_hal_ ) after the function tfm_arch_set_secure_exception_priorities() has been called. What would be the best way to fix the current issue which could also arise on other platform ? Regards, Romain
