Hi everyone,

I'm writing my own bootloader for STM32f407VG, in the start address of flash memory. But getting problem GetID command is not acknowledged. I've attached a log also.

I'm receiving the GetID command and sending the response as below.

       uint8_t id_size = 0x01;
	
       uart_write(ACK_BYTE);
       uart_write(id_size);
       uart_write(DEVICE_ID_MSB);
       uart_write(DEVICE_ID_LSB);
       uart_write(ACK_BYTE);

I think I've figured out the problem, this was happening because I've not written the read memory execution carefully. After correcting this problem now it's working.

I've debug it, it's going inside that function and other data is passing.
