If you don't want to use this channel for console I/O, but just want to add an extra download command to redboot that you can add to the boot script, then you can do that using something like:

# include "redboot.h"

RedBoot_cmd("lvds_load",

"load over LVDS",

"[-w <timeout>]",

do_lvds_load

);

void

do_lvds_load(int argc, char *argv[])

{

// load the code

}

This will cause the function do_lvds_load() to run whenever the command lvds_load is issued.

If you look in packages\redboot\v2_0\src (in particular at main.c), you&#39;ll see examples of this.
