Hi Ken,
Yes, we are using L2. I have just switched to the latest commit which includes the suggested fix. But tfm_nspm_thread_entry() still goes to the MemManage_Handler() fault a bit later on "push {r0, r1} \n"
Thanks, Andrej

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.

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
1. 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
