I think, I have "bricked" my STM32WB55 Nucleo board.I can connect the board in system boot mode via ST-Link in ST-Programmer. The SFSA value is 0x00 (0x0800 0000).Because SFSA can only be written by CPU2 and embedded flash is write protected:Is there...

I forgot to mention DDS=1 (CPU2 debug access disabled) and FSD=0 (System and Flash memory secure (the secure area of the Flash memory is given by SFSA)).

STM32WB55, SFSA value is 0x00 (0x0800 0000). Is there a way to execute some code for CPU2 from RAM to modify the SFSA setting?
