Hi Andrej,
Could you provide us with instructions on how to replicate the issue you're observing? In particular, which build configuration you're building (.cmake), compiler, platform used and if it's observed on board or FVP/model? Also, are you able to identify the latest commit which was still working in your setup / identify the commit which brings in this issue?
Thanks, Antonio

Father investigation shows, that tfm_pendsv_do_schedule() calls tfm_thrd_context_switch() and passing pth_curr which is set to NULL, so it is causing memcpy() to 0 address => Bus Fault. So this code may not work properly. Please provide a fix.

Hello,
After last commits on TFM master branch, when TFM_PSA_API is defined, the tfm examples finish in main()=>tfm_spm_init()=>....=> tfm_thrd_context_switch()=>tfm_memcpy()=>BusFault_Handler(). When TFM_PSA_API is not defined, everything is OK. Also, TFM examples were OK at least 2 weeks ago, even when TFM_PSA_API was defined.
Is it known issue? Or something new (during last week) must be added into our target-specific code?
Thanks, Andrej Butok
