Hi,
I have a product with 2 microcontrollers on the same PCB(running independently). One is STM32G030 and other is STM32WB5MMG(ble module containing STM32WB55). I enabled internal bootloader(via option bits configuration) for both the microcontrolelrs(via usart1). The G030 works perfectly and already flashed and checked new firmware.
But when trying on WB5, the systems goes into bootloader at powerup, but it is not responding to command(0x7F). Even though according to AN2606, 3155 and RM 0434, the bootloaders shoudl behave same on both systems.

Hello @KlemenDS
Could you provide more details about your option bytes values. Also, what are the PINs that you are using for USART1?
Best Regards.
