Re: [TF-M] Externally override flash layout and pin configurations (out-of-tree platforms?)

by Rønningstad, Øyvind

Deprecation of platform MPS2/SSE-200_AWS

by Marton Berke

Hi Everyone, I would like to propose the deprecation of platform MPS2/SSE-200_AWS because the platform is no longer available to use: https://aws.amazon.com/marketplace/pp/ARM-Ltd-DesignStart-FPGA-on-Cloud-Cor… As per the process, this proposal is open for discussion for a period of 4 weeks and if there are no major objections, the platform should be marked as deprecated and removed from TF-M master after next release. Thanks and Best regards, Marton Berke

Re: [TF-M] Externally override flash layout and pin configurations (out-of-tree platforms?)

Hi, In the ideal case with HAL API, the platform itself can decide which variant's layout to be applied, selected by build system switches or just some header files. Because SPM could get what it needed by HAL API run-time. It can be mostly done inside the platform folder if one platform has the variants management already.

Re: [TF-M] MCUBOOT_LOG_LEVEL description confusing/wrong

by Tamas Ban

Hi Thomas, Here is the fix: https://review.trustedfirmware.org/c/TF-M/trusted-firmware-m/+/7196 Actually since the CMake refactor the default value can be overridden from the command line, so it is possible to enable the logging even in Release builds. BR Tamas -----Original Message----- From: TF-M <tf-m-bounces(a)lists.trustedfirmware.org> On Behalf Of Thomas Törnblom via TF-M Sent: 2020. november 25., szerda 8:50 To: tf-m(a)lists.trustedfirmware.org Subject: [TF-M] MCUBOOT_LOG_LEVEL description confusing/wrong The description of how to set MCUBOOT_LOG_LEVEL in tfm_secure_boot.rst appears wrong, or at least unclear. --- - MCUBOOT_LOG_LEVEL: Can be used to configure the level of logging in MCUBoot. The possible values are the following: - **LOG_LEVEL_OFF** - **LOG_LEVEL_ERROR** - **LOG_LEVEL_WARNING** - **LOG_LEVEL_INFO** - **LOG_LEVEL_DEBUG** The logging in MCUBoot can be disabled and thus the code size can be reduced by setting it to ``LOG_LEVEL_OFF``. Its value depends on the build type. If the build type is ``Debug`` and a value has been provided (e.g. through the command line or the CMake GUI) then that value will be used, otherwise it is ``LOG_LEVEL_INFO`` by default. In case of different kinds of ``Release`` builds its value is set to ``LOG_LEVEL_OFF`` (any other value will be overridden). --- I tried enabling MCUBOOT_LOG_LEVEL_DEBUG by adding -DMCUBOOT_LOG_LEVEL=LOG_LEVEL_DEBUG to the cmake command line, but that set the level to -1. I also tried -DMCUBOOT_LOG_LEVEL=4, which also set it to -1. I then noticed that the default setting in CMakeCache.txt is "MCUBOOT_LOG_LEVEL:STRING=INFO", so I instead used -DMCUBOOT_LOG_LEVEL=DEBUG, which worked. I would also like to be able to use logging for Release builds, as this may assist chasing down optimization issues.
