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

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 dochttps://tf-m-user-guide.trustedfirmware.org/docs/technical_references/design_docs/tfm_fwu_service.html?#additional-shared-data-between-bl2-and-spe 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,
Bohdan Hunko
