STM32L562QE: "No source available for <signal handler called>() at 0xfffffffe"

[Claudia]

Hello,

A few days ago I compiled on my STM32l562E-DK board the TFM application (which includes TFM_SBSFU_Boot, TFM_Loader, TFM_Appli) of STM32Cube_FW_L5_V1.5.0 package. After that I experienced some errors. The first one was DEV_TARGET_NOT_HALTED which I managed to solve by doing a boot from RSS. Then, I tried debugging the example project “GPIO_IOToggle_TrustZone_Secure” and I got the second error: “No source available for <signal handler called>() at 0xfffffffe” and “failed to execute MI command. Error message from debugger back end: Cannot access memory at ...“.

This happens with any TrustZone enabled project I try to debug.

I would appreciate any tip or assistance. Than you in advance!
