Hello All,

We are using STM32F407VG & are having issues with bootloader via USART3 PC10/PC11. From the SW, we see that the processor is entering the bootloader mode.

When 0x7F is send, the processor responds with "0x00 0x00 0x00" instead of 0x79.

We are using BR-9600, 8Bit, Even parity & 1 stop bit. We have been struggling for over a week now & have no clue what we are missing. Looking for some help or guidance!

Thanks in advance.
