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] gcc compiler requirement documentation

Hi Chris, Thanks for point out this. Here is the fix: https://review.trustedfirmware.org/c/TF-M/trusted-firmware-m/+/7226 Regards, Shawn From: TF-M <tf-m-bounces(a)lists.trustedfirmware.org> On Behalf Of Christopher Brand via TF-M Sent: Thursday, November 26, 2020 2:55 AM To: tf-m(a)lists.trustedfirmware.org Subject: [TF-M] gcc compiler requirement documentation Looking at docs/getting_started//tfm_sw_requirement.rst it says that the version requirement for gcc is "GNU Arm compiler v7.3.1+". then it describes where to get that toolchain, but in that section the two versions it suggests are "GNU Arm Embedded Toolchain: 6-2017-q1-update" and "GNU Arm Embedded Toolchain: 7-2018-q2-update". The former is gcc version 6.3.1, which doesn't actually meet the requirements. Chris Brand Sr Prin Software Engr, MCD: WIRELESS Cypress Semiconductor Corp.

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

by Ken Liu

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. Others please give inputs as this is a very useful topic, we can list down the problem we met during integration first. BR /Ken From: TF-M <tf-m-bounces(a)lists.trustedfirmware.org> On Behalf Of Rønningstad, Øyvind via TF-M Sent: Thursday, November 26, 2020 3:47 AM To: tf-m(a)lists.trustedfirmware.org Cc: Rasmussen, Torsten <Torsten.Rasmussen(a)nordicsemi.no> Subject: [TF-M] Externally override flash layout and pin configurations (out-of-tree platforms?) Hi all In our work integrating TFM into Zephyr and the nRF Connect SDK, it's apparent that the integration would be a lot smoother if we could specify TFM's flash layout externally. Looking into it a bit, I came up with a draft proposal here: https://github.com/zephyrproject-rtos/trusted-firmware-m/pull/18/files We could just modify our own platforms to this and be happy, but I'm wondering if there would be interest in standardizing something. Now, a related problem is: How can we make it easier to add multiple boards based on a single chip. For the Nordic platforms we've already separated the chip-specific code (nRF9160/nRF5340) from the board specific code (DK/PDK), and for the boards, it really boils down to pin configurations. We could allow to specify pins via Cmake instead, to easily allow users to support their production PCBs. But (this was brought up in the above PR) we can also solve both problems by adding support for out-of-tree platforms. For example, allow TFM to be built like so: cmake -DTFM_PLATFORM=../../../../my_custom_board ... This would probably be less work that designing a new interface for overriding flash layouts and pin configurations. What are your thoughts? BR, Øyvind Rønningstad

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.
