Hi! I decide to use the integratet bootloader by UART. In my application the TX-Pin is invertert and so I enable "TX Pin Active Level Inversion" in CubeMX. That will work for my application program. Does ist work for the bootloader also? Bernd

No, any special pin settings made in CubeMX won't be applied to the bootloader as it resides in ROM.
