Hello,
I have a B-U585I-IOT02A board, and I followed the tutorial at Getting started with STM32CubeU5 TFM application - User manual. Unfortunately, I couldn't get it to work and I tried to rollback, following the steps described in Section 10.6 STM32U5 device reinitialization, but I couldn't get my device reinitialized to the RDP=0 level.
The default password that I used in regression.sh is 0xFACEB00C 0xDEADBABE, switch SW1 (BOOT0 pin) is on position 1, and I connected TAMP_IN8 (PE4 on CN3 pin 11) and TAMP_OUT8 (PE5 on CN3 pin 14) as suggested in Solved: STM32U585 DOES NOT RETURN TO RDP=0. - STMicroelectronics Community
But I still get the same errors:
