Hi Andrej,

I guess you are using the level2 configuration. This fault was caused by tfm_nspm_thread_entry is trying to call a function in the privileged area.

This commit ‘cba90782908626f955fe361f803558181a85c6fc’ fixes this problem.

Subject: [TF-M] Stuck in tfm_nspm_thread_entry() after "Initialize IPC SPM in handler mode"

Hello,

Just want to check if this is a known issue.

During synchronization to the latest TFM, TFM applications are stuck in the exception handler tfm_nspm_thread_entry ()=>MemManage_Handler().

This issue has been caused by commits (3.1.2020):

1. Revision: 5248af2d7b86775364a0e131eb80ac0330bc81fb

Message: Core: Use naked function for ns jumping

2. Revision: 490281df3736b11b62e25bc98d3e2c6e4e10478c  

Message: Core: Initialize IPC SPM in handler mode

The previous commit is fully OK (committed 2.1.2020):

Revision: 93dabfd3a35faf9ed88285e09997491e93cefa5c

Message: Core: Trigger a system reset for programmer error

The commits do not have any changes in the linker files and no changes in target files, only the common and ARMv8 code.

It’s good to know if this is something known or met before.

Thank you,

Andrej
