NOOB: Programming DM355 without networking....

Amer Abufadel5389

Hello all,

  This might be a naive question, but is it possible to program the DM355 EVM without having a network connection?
  What I would like to do is to grab a frame from a video source and save it to an SD card.  However, the application has a size constraint that cannot afford the extra hardware.
  How do the experts go about doing this?  Perhaps a breakout board?  I would like to use the evaluation JPEG codecs but these run on Montavista...
  Any pointers appreciated...

    One way would be to

    1) Place u-boot (boot laoder)  and uImage (Linux kernel) in NAND flash.  Linux kernel would have SD card support enabled of course.

    2) Place Linux filesystem (containing your program, JPEG codec,...) in SD Card

    3) Configure u-boot to load Linux Kernel from flash (which will enable SD card) and mount file system from SD card (this is done by setting u-boot bootargs accordingly)
