Serial downloader with UART1

hongtao_li — Mon, 02 Mar 2020 08:20:10 GMT

Hi all,

I am trying to flash the bootloader to imx6ul board in serial downloader mode with UART1.

First, I send the DCD data with SDP command DCD_WRITE, and the response WRITE_COMPLETE(0x128A8A12) is received.

Then I send the bootloader with SDP command WRITE_FILE, but I cannot receive the response COMPLETE(0x88888888).

If I don't write the DCD, but only the bootloader after power on into serial download mode, the response COMPLETE(0x88888888) can be received.

Can anyone tell me why?

Thanks.

Best regards.
