Hi ,

I am working over the IMX6 solo which is interfaced with serial NOR Flash. As per the Reference Manual , Table 8-1 ,

Serial Downloader mode can be used for firmware flashing. But Serial Downloader mode requires serial USB. In my target board USB board is not populated. My questions are as follows :


1. Can I flash uboot using debug UART ?  if yes then please explain how .

2 . In which mode IMX6 will boot up to write the NOR Flash using UART.

Please suggest.
