Hello, I tested my board port on top of 1c266ae74bd93c2ef290e9aac0caecf92b06b93d Without option -Os , the tests with ConfigCoreIPC.cmake are passed . When I put the option -Os , 1st test is failing in Hardware Fault. For info, the test with ConfigRegression.cmake and option -Os is passed . With the configuration -Os , code footprint is much better. Is it plan to activate this option in master ? Is the same issue reproduced on another board ? Best regards

Re: [TF-M] PSA Test Suite forum?

by Andrej Butok

Hi Antonio, Ok, so the TFM is using the old API. Hope, it will be updated soon. I prefer do not downgrade the test suite from master, as it contains >50 of new commits.

[RFC] Isolation level 2 patches

by Ken Liu (Arm Technology China)

Hi, The isolation level 2 patches are pushed for reviewing; you can find all of them under the issue: https://developer.trustedfirmware.org/T294 The design document was put at: https://developer.trustedfirmware.org/w/tf_m/design/trusted_firmware-m_isol… The first group of patches are working on AN521 with ARMCLANG build. Rest options supporting would come later. With higher isolation level, some functions may not work such as CLIB (malloc/free e.g.). These features need to be supported after dedicated implementation is done. You can check the [RFC] discussion sent in mailing list of the isolation level 2 for details. Isolation level 2 use dedicated config file: "ConfigCoreIPCTfmLevel2.cmake" so the IPC on isolation level 1 is not affected by this change. Please help to comment in documents and patches - current the document has no comment area so you can put comments under the issue link, or just reply in mailing list. Creating issues is another valid options ; ) Thanks! -Ken

Re: [TF-M] [EXTERNAL] Re: Please explain tfm_register_client_id() use case

by DeMars, Alan

Yes, that idea would resolve the problem. I’m not sure I understand the use case for multiple updates to a context’s client Id. What is the thought behind that?

This creates pressure for tfm_register_client_id() to be called during a NS thread switch. However, calling tfm_register_client_id() on EVERY NS context switch is redundant and CPU wasteful.

Re: [TF-M] [RFC] twin cpu bootloader design document

by David Hu (Arm Technology China)

Hi Chris, Sorry for the delayed reply. Please check my comments in below. Just about small details. Please correct me if I misunderstand anything. 1. In my own opinion, it can be possible to use IPC to synchronize mailbox services between two cores, during initialization. The synchronization is only trigged when the mailbox mechanism is ready on mailbox server or client. It means that the IPC module should be also configured. Based on the above assumption, using IPC to synchronize the two cores is more generic and convenient than accessing shared memory. If using shared memory to pass status flag, it can be necessary to adjust the address of the shared memory occasionally according to the memory assignment in different applications. 2. I'd like to suggest that we shall discuss more about when the booting HAL APIs are invoked in TF-M. `tfm_core_init()` initializes the TF-M core. Thus in theory, `tfm_core_init()` is irrelevant to the system topology or platform implementations. As a result, IMO, it can be more reasonable to put the HAL APIs outside the `tfm_core_init()`. 3. ` tfm_spm_hal_wait_for_ns_cpu_ready()` can be optional. The secure core acts as a server and it is driven by the request from NS core. The secure core actually doesn't have to wait for an explicit signal to know NS is ready. The synchronization can be guaranteed if NS core starts request via mailbox only after secure core is available. 4. It can be unnecessary to require calling `tfm_spm_hal_wait_for_s_cpu_ready()` in NS `main()`. It might be too early to wait in `main()` and may block other initializations which don't rely on mailbox. This API can be invoked in mailbox functionalities. The whole NS initialization can continue, including enabling application threads, until a NS application requests Secure services via mailbox at the very first time. Thus the whole dual core design can be more generic since the mailbox workflow should be identical on diverse platforms. And we can save the time and effort to hack each RTOS initialization. In other words, I wonder if we can make calling `tfm_spm_hal_wait_for_s_cpu_ready()` in NS `main() as an option and allow other implementations. Thank you.

proposed change in Musca B1

by Tamas Kaman

Hi All, I'd like to notify everyone about a proposed change in Musca B1 platform in TF-M. Everyone who is using that platform might be affected. The code on Musca B1 is currently running from the external QSPI flash. With the coming change this moves to a much faster internal embedded Flash, so all you might observe is faster code execution. Link to review: https://review.trustedfirmware.org/#/c/trusted-firmware-m/+/669/ Also, for loading the image to the a board another version of DAPLink FW will be needed. The eFlash type DAPLink FW can be downloaded from Arm Community page: https://community.arm.com/developer/tools-software/oss-platforms/w/docs/425… A short description of how to update the DAPLink FW can be found here as well.
