DM385 MMC/UART boot

Other Parts Discussed in Thread: DM385

Hello,

We are not able to boot DM385 custom board. However, we are getting "CCC" chars on terminal and stops after 8-9 prints. We can also send image via XMODEM as per the procedure but nothing happens after that. Everything seems to be ok..i.e Power/Clocks/resets etc...Any pointers on this.

    what is the size of the binary that you are sending via XMODEM?
    Did you compiled the U-Boot with uart + min configuration?
    You can refer to the following wiki for Uart Boot mode

    Hello,

    we have followed the procedure and UART binary file size is close to 56K. Actually we are able to download from XMODEM but not able to get the prompt even after many enters. Is it that DDR3 config has some issues. We are also trying to print chars before DDR gets configured...but that is also not happening..any clues.
