Hi Bohdan,

Assume you are aware that the CODE sharing topic was discussed in Tech forum on Oct 29, 2020.

You can find presentation and the records here: https://www.trustedfirmware.org/meetings/tf-m-technical-forum/

Hope that helps,

Anton

Subject: [TF-M] BOOT_TFM_SHARED_DATA_* usage in arm/musca_b1

Hi everyone!

I see definitions of BOOT_TFM_SHARED_DATA_* in platform\ext\target\arm\musca_b1\sse_200\partition\region_defs.h but I don’t see any real usage of that memory.

I have found TF-M doc that describe usage of shared memory  for Firmware Update Service but once again I was not able to find any code that uses that.

I would appreciate if someone could point to docs on this or to code that actually uses shared data between BL2 and TF-M SPE.

Best regards,
