We are currently pre-occupied with the 5.12 release, you can look at Mbed-os PR#10027 to see how we solved this issue.

Can you elaborate on the root cause?

Inside the svc_handler if you check LR, which holds EXC_RETURN.

We are experiencing this issue on the NXP LPC55S69 MCU, which is Cortex-M33-FE core.

mikisch81 added a comment to T234: GCC/Release: Compiler optimizes tfm_core_ns_ipc_request() too much.

A workaround for us which fixed this issue was setting the descriptor struct volatile:

volatile struct tfm_sfn_req_s desc;
struct tfm_sfn_req_s *desc_ptr = &desc;
