Hello, I'm a RSE firmware developer for Arm Neoverse V3 core. I tried to build with argument MCUBOOT_ENC_IMAGES, MCUBOOT_ENCRYPT_RSA, and MCUBOOT_USE_PSA_CRYPTO for RSE PE encryption. In this process, I encountered an error during build TF-M using the repo for tag:RD-INFRA-2025.07.03. It seems that linking problem, and I found out that the error occurred while configuring BL2. However, that's all. Can anyone help me? Below log is in my terminal output.  p.s. If I reached wrong site, please forgive me and teach me a right one. cmake --build build --target bl2 [  0%] Built target manifest_tool [  0%] Built target bl2_scatter [ 10%] Built target bl2_cc3xx_psa_driver_api [ 31%] Built target bl2_cc3xx [ 68%] Built target platform_bl2 [ 78%] Built target bl2_crypto [ 94%] Built target bootutil [ 94%] Linking C executable ../bin/bl2.axf /home/gth1919/gcc-arm-none-eabi/bin/../lib/gcc/arm-none-eabi/10.3.1/../../../../arm-none-eabi/bin/ld: ext/mcuboot/bootutil/libbootutil.a(encrypted.o): in function `bootutil_rsa_oaep_decrypt': /TF_M/build/lib/ext/mcuboot-src/boot/bootutil/include/bootutil/crypto/rsa.h:107: undefined reference to `psa_asymmetric_decrypt' Memory region         Used Size  Region Size  %age Used            FLASH:       80356 B       126 KB     62.28%              RAM:       35360 B       896 KB      3.85% collect2: error: ld returned 1 exit status gmake[3]: *** [bl2/CMakeFiles/bl2.dir/build.make:222: bin/bl2.axf] Error 1 gmake[2]: *** [CMakeFiles/Makefile2:2661: bl2/CMakeFiles/bl2.dir/all] Error 2 gmake[1]: *** [CMakeFiles/Makefile2:2668: bl2/CMakeFiles/bl2.dir/rule] Error 2 gmake: *** [Makefile:520: bl2] Error 2 HP.

Proposal to deprecate Musca-S1 and BL5340_dvk_cpuapp platforms

by Anton Komlev

Hi everyone, We would like to propose the deprecation of the following two TF-M platforms: 1. Musca-S1 (Arm) Musca-S1 was one of the earliest platforms featuring an Armv8-M silicon implementation, providing a valuable real hardware target for initial development. However, with the availability of many modern hardware platforms, Musca-S1 is no longer essential and can be deprecated. 2. BL5340_dvk_cpuapp (Laird Connectivity) This platform was initially proposed for deprecation at the end of 2023. Support activity has been minimal, and it closely mirrors the already-supported nRF5340 platform from Nordic Semiconductor. Please share any comments or objections regarding this proposal. If no major concerns are raised by the end of June 2025, we plan to mark these platforms as deprecated and proceed with their removal from the codebase. Thank you, Anton

Trusted Firmware Gerrit issues

by Matthew Dalzell

Hi All, We have recently undergone a migration of our Gerrit server and are seeing some issues. One such change appears to be that https://review.trustedfirmware.org/TF-M/trusted-firmware-m no longer resolves to https://review.trustedfirmware.org/plugins/gitiles/TF-M/trusted-firmware-m. So please use the latter link if that is what you wish to access. This is causing a large slow-down on the CI causing jobs to not be run. These issues are being actively worked on and we hope all will be back up and running normally soon. If you have any questions or related issues please feel free to respond to this chain. Thank you for your patience, Matt

Constrains of key ownership in TF-M

by Norrathep Rattanavipanon

Hello, I just recently found out that there's a concept of key ownership in TF-M (e.g., if a new secure partition creates a key and returns the key handle to NSPE, NSPE can't export it even if the key is config-ed to be exportable -- the key can only be used by the owner). My question is: is this design based on PSA or specific to just TF-M implementation?

Question about build error in TF-M release/2.2.x

by Zhang, Hao

Hi TF-M community, When I am trying to build TF-M regression test for 2.2.x release, I sets the tf-m-tests repo version to recommended TF-Mv2.1.2-RC2. The tf-m-tests tests_reg/spe/CMakeLists.txt has following line: install(FILES ${CONFIG_TFM_SOURCE_PATH}/lib/ext/qcbor/q_useful_buf.h DESTINATION ${CMAKE_BINARY_DIR}/api_ns/qcbor/inc) However, release 2.2.x https://git.trustedfirmware.org/plugins/gitiles/TF-M/trusted-firmware-m.git… has removed q_useful_buf.h. Therefore, causing a build error. Is there anything I am missing. Any help would be appreciated. Best regards, Hao

Build failure of release/2.1.x

by Zhang, Hao

Dear whoever that may concern, I am trying to build TF-M with release/2.1.x. The first error I see when cloning mbedcrypto is Cloning into 'mbedcrypto-src'... remote: Enumerating objects: 31188, done. remote: Counting objects: 100% (31188/31188), done. remote: Compressing objects: 100% (15898/15898), done. remote: Total 31188 (delta 24658), reused 20224 (delta 15043), pack-reused 0 (from 0) Receiving objects: 100% (31188/31188), 35.81 MiB | 4.89 MiB/s, done. Resolving deltas: 100% (24658/24658), done. fatal: invalid reference: f985bee CMake Error at mbedcrypto-subbuild/mbedcrypto-populate-prefix/tmp/mbedcrypto-populate-gitclone.cmake:40 (message): Failed to checkout tag: 'f985bee' I therefore change the GIT_SHALLOW to FALSE, and it builds. However, another build error come up when applying patches for mbedcrypto. Checking patch library/psa_crypto.c... Checking patch library/psa_crypto_driver_wrappers.h... error: library/psa_crypto_driver_wrappers.h: No such file or directory Checking patch library/psa_crypto_driver_wrappers_no_static.c... error: library/psa_crypto_driver_wrappers_no_static.c: No such file or directory I did checkout commit f985bee and find in fact there is no psa_crypto_driver_wrappers.h. Is it possible that the commit hash is incorrect? Best regards, Hao

by Takekazu Tabata (Fujitsu)

Dear TF-M Team, I'm Takekazu Tabata, a director and architect from the Fujitsu processor team. We are currently developing FUJITSU-MONAKA, which supports the CCA feature. We have three questions regarding the TF-M documents and TF-M implementations. We would greatly appreciate it if you could provide answers. Question 1) In the TF-M document “RSE provisioning”, The CM provisioning Key is used to encrypt DM Provisioning Bundle. https://trustedfirmware-m.readthedocs.io/en/latest/platform/arm/rse/rse_pro… After the cold reset, the RSE will automatically transition to Device Manufacturer provisioning state “DM” as the LCM hardware state-machine reads the values of the cm_config_1 and cm_config_2 fields as non-zero. This state is designed to provision the DM provisioning key, the DM code-encryption key and the DM config. The procedure follows the same steps as the CM provisioning flow, with the exception that the bundle will now be encrypted and signed using the CM provisioning key and must be placed at the base of VM1. However, the purpose of the data provided in the DM is not described in this document. These data are not used in the source code of TF-M v2.2.0. DM provisioning is probably assumed to be done during device manufacturing, but could you explain the purpose in more detail? Also, What are the DM provisioning key, the DM code-encryption key and the DM config used for? Question 2) In the TF-M document “RSE integration guide”, attestation key(CPAK) is derived by GUK. https://trustedfirmware-m.readthedocs.io/en/latest/platform/arm/rse/rse_int…<https://trustedfirmware-m.readthedocs.io/en/latest/platform/arm/rse/rse_int…> The GUK is a key unique to a group of chips that have identical security properties, used to derive the attestation key. However, CPAK is derived from HUK in the source code of TF-M. GUK in the specification is a typo. https://git.trustedfirmware.org/plugins/gitiles/TF-M/trusted-firmware-m.git…<https://git.trustedfirmware.org/plugins/gitiles/TF-M/trusted-firmware-m.git…> /* This derives from HUK, there is a typo in the spec, not from GUK. * FixMe: this should be configurable per platform */ return setup_key_from_derivation(KMU_HW_SLOT_HUK, NULL, iak_seed_label, sizeof(iak_seed_label), NULL, 0, RSE_KMU_SLOT_CPAK_SEED, /* FixMe: The slot needs rename to IAK_SEED */ &aes_key0_export_config, NULL, false, boot_state_config); Which is right, GUK or HUK? If it‘s HUK (not Virtual HUK), is it no problem that multiple CPAKs are generated in Multi-socket systems? Question 3) In the CM/DM lifecycle state, is it no problem to create an original provisioning bundle to run chip or device verification programs in PE? Thank you for your time and assistance. Best regards, TABATA
