I'm not sure what "master" is but I transfer the firmware from a different MCU connected to the ST MCU via UART.The required firmware can be provided to the host MCU via USB, UART, BLE, or external storage.Regarding the timing, I agree with what you ...

For anyone else who might be having problems with the integrity of the data written by the bootloader.I managed to get my issue resolved by pausing 2 milliseconds between each byte transmission.Without the small delay, the firmware programmed by the ...

Not quite there yet.....The UART communication appears to be working and all the memory writes are correctly ACK'ed by the bootloader. However, when I dump the flash contents from the MCU, the retrieved bytes does not match those from the original fi...
