Global Erase for STM32WB55

[metal2oxide]

I want to know whether any option bytes should be set before doing global erase for STM32wb chip. After the initial 0x44 and 0xBB, the device doesnt respond to global erase command (0xFFFF).

Hello,

You can perform a full chip erase using STM32CubeMX tool. Which option bytes have you changed, the read out protection option bytes?
