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

Please review a new design proposal guideline

by David Hu

Hi all, As part of the documentation improvements, a new design proposal guideline [1] is proposed to replace and simplify the current process. The basic idea is to encourage developers to share their design via mailing list and tech forum, without a well-formatted design document. If developers prefer a document for a new feature, please provide an integration guide/user manual instead. Please check the details in the patch below. [1] https://review.trustedfirmware.org/c/TF-M/trusted-firmware-m/+/14104 The rendered html version: https://ci-builds.trustedfirmware.org/static-files/KTOoRMhB4VsgNQFkdMgWZcZG… Best regards, Hu Ziji

Issues with psa_wait() when waiting for interrupts and IPC function calls.

by Martin Gunnarsson

Hello, I am trying to write an Application RoT for a research project I am a part of. I have run into an issue that I have been unable to solve independently. My problem is the unexpected behavior of psa_wait() when using signal masks. I have two signals, TFM_TIMER1_IRQ_SIGNAL and TFM_SECURE_FUNCTION_SIGNAL. The TIMER1_IRQ signal is triggered by an FLIH interrupt handler that returns TFM_FLIH_SIGNAL. The interrupt is triggered every 1 second by TIMER1. The TFM_SECURE_FUNCTION_SIGNAL is triggered by a periodic function call from the NSPE (a Zephyr thread) and is called every 10 seconds. Observed result: If PSA_WAIT_ANY is used as a signal mask, the TIMER0_IRQ_SIGNAL will only be received when TFM_SECURE_FUNCTION_SIGNAL is received, ergo, every 10 s. Thus any stage 2 handling of an interrupt would be missed. If TFM_TIMER1_IRQ_SIGNAL is used as a signal mask, the signal will be received every 1 s as expected. The TFM_SECURE_FUNCTION_SIGNAL will never be received, as can be expected in the NSPEtoo. I have tried a "hybrid approach" where I call psa_wait(TFM_TIMER1_IRQ_SIGNAL, PSA_BLOCK) /* handle signals .... */ and then psa_wait(TFM_SECURE_FUNCTION_SIGNAL, PSA_POLL). The stage 2 IRS is called, and the secure function is also called. But not with the regularity that I would like. Am I missing something obvious? I have read the Secure Interrupt Integration Guide and carefully studied the SLIH and FLIH test services for the TF-M regression tests. Have I forgotten to reset a signal somewhere? Does the interrupt not preempt the NSPE? I would be immensely grateful for any or all responses. If you need more information, please let me know.

New API tfm_hal_system_halt()

by Bøe, Sebastian

Hi, in the effort to ease debugging by supporting a choice between halting and rebooting we are introducing a new HAL API: void tfm_hal_system_halt(void) which by default (weak) does: __disable_irq(); while(1) { __WFE(); } CPUs cannot halt. But they can sleep until they are awoken in a loop, which is pretty close. tfm_hal_system_halt() is, when configured so, used by tfm_core_panic() which is why we disable irqs to stop all threads of execution, not just the thread that is executing. Currently it is proposed that tfm_core_panic() halts when TFM_HALT_ON_CORE_PANIC is ON and otherwise reboots. TFM_HALT_ON_CORE_PANIC is default ON if and only if Debug mode is enabled. Any feedback to these changes are welcome, and if any platform needs to halt in a different manner then a contribution would be welcome as well. https://review.trustedfirmware.org/c/TF-M/trusted-firmware-m/+/13839

TF-M regression test refinements

by Jianliang Shen

Hi, all I'd like to share two new refinements in TF-M test repo to you. l The struct variable test_result_t has been removed from the definition of struct variable test_t. It is unnecessary to set an initial value of test result for each case. With this change, the binary size will be reduced. Please see [test patch]<https://review.trustedfirmware.org/c/TF-M/tf-m-tests/+/13822/4> for more details. l The flag TEST_SKIPPED has been added into enum variable test_status_t, works with TEST_PASSED and TEST_FAILED. TEST_SKIPPED indicates that the test case is skipped in runtime when the test environment is unavailable. Please ee [test patch]<https://review.trustedfirmware.org/c/TF-M/tf-m-tests/+/13826/5> for more details. Hope these two changes can help your work in the future. Please let me know if anything can be improved. Thanks! Best Regards Jianliang Shen

FF PSA API overhead

by Bøe, Sebastian

Hi, the performance improvement presentation[0] reports a FF PSA API overhead of 20 000 CPU cycles for the psa_call. Which is 300 us for a 64MHz CPU. This is quite a lot of instructions and I am concerned about whether real world embedded application's will have time to call these secure services. I'm interested in isolation level 2. I understand that it is not possible to have isolation level 2 with library mode. But what about SFN mode, could that eventually support isolation level 2? If not, what is the current status of optimizing the service call overhead for IPC. Is it considered to be as optimized as it can be or is there still hope for optimizing further?

halting or rebooting on faults

by Bøe, Sebastian

Hi, it seems we could try to be more consistent with fault handling. The current default behaviour is: Error code returned from an SPE function? Reboot. MemFault/HardFault/SecureFault in the SPE? Halt. Null-pointer dereference from the NSPE? (results in a secure fault for cortex-m) Halt. Should we perhaps consistently halt or consistently reboot for these three cases and allow this to be configurable? It is not clear to me why an error returned from a function results in a reboot, whereas a Hardfault does not. They both indicate a fault in the SPE. At the very least the behaviour should be configurable, which this PR is a step towards: https://review.trustedfirmware.org/c/TF-M/trusted-firmware-m/+/13839

Why ARM_FLASH_STATUS is volatile in flash driver?

by Roman Mazurak

Hi all, Why ARM_FLASH_STATUS was declared volatile in https://git.trustedfirmware.org/TF-M/trusted-firmware-m.git/commit/platform… commit ? I believe it's much better to declare volatile variable when there is such need instead of forcing all variables to become volatile through typedef. Thanks, Roman.

Custom implementation of of tfm_hal_system_reset

by Bohdan.Hunko＠infineon.com

Hi everyone, I have a few questions related to TF-M code: 1. Default implementation of tfm_hal_system_reset(void) from platform/ext/common/tfm_platform.c<https://git.trustedfirmware.org/TF-M/trusted-firmware-m.git/tree/platform/e…> just calls NVIC_SystemReset(), but some ARM platform, take musca_b1 for example, reimplement it (platform/ext/target/arm/musca_b1/sse_200/tfm_hal_platform.c<https://git.trustedfirmware.org/TF-M/trusted-firmware-m.git/tree/platform/e…> ). Custom implementations tend to also disable and clean IRQ and call mpc_revert_non_secure_to_secure_cfg(); Is there any benefits of doing that??? If so then what those benefits are? 1. tfm_core_panic() (secure_fw/spm/ffm/utilities.c<https://git.trustedfirmware.org/TF-M/trusted-firmware-m.git/tree/secure_fw/…>) when TFM_FIH_PROFILE_ON is defined calls fih_delay() and tfm_hal_system_reset() twice. Is this done to ensure that tfm_hal_system_reset() will be called (even if first one was skipped there is second one)? And if so, can a comment be added there to highlight that intention?

Remove use of ER_INITIAL_PSP

by Mingyang Sun

Hi, ER_INITIAL_PSP section was used as the Trustzone NS Agent partition stack in IPC model. Since Trustzone NS Agent partition has changed to use private variables as its stack, ER_INITIAL_PSP related definitions and references can be removed. Change: https://review.trustedfirmware.org/c/TF-M/trusted-firmware-m/+/13186 This change involves all the platforms for IPC model, it removes: * Definition of ER_INITIAL_PSP section in the linker script * Reference of ER_INITIAL_PSP for isolation configuration in platform HALs This can simplify the linker script a bit. This patch is going to be put there for a while as there are holidays, but please do review it when you see this mail. Plan to merge it before end of Jan, as soon as all concerns get addressed (if there are). Regards, Mingyang

Code size analyze tool for TF-M further optimization

by Jianliang Shen

Hi all, I'd like to introduce a code size analyse tool to you. The tool is developed to help optimize TF-M code size by gathering the data from map file and output friendly. These python scripts can - Get a database to implement data tables from ARMCLANG or GNUARM map file. - Supply an UI for developers to scan sorted information of sections, libraries, object files, functions and data. - Help analyse the biggest or smallest targets in certain image. It can also help search functions or data to locate their address and detail information. - Diff two databases to see the code size increment or decrement between two different build results. The patch is: [tf-m-tools]<https://review.trustedfirmware.org/c/TF-M/tf-m-tools/+/12665>, it also contains the document for users. Hope this tool can help you measure code size in the daily work. Please let me know if anything can be improved. I'd like to merge this tool this Friday if no critical comment. Best Regards Jianliang Shen
