Hi

I assume that you share the file either with TFTP or HTTP server

    load -m tftp path_to_filename [more load opts]
    load -m http path_to_filename [more load opts]

For reference: http://ecos.sourceware.org/docs-latest/redboot/download-command.html

* FIS (optional)
* CDL (see CDL option CYGDAT_REDBOOT_DEFAULT_BOOT_SCRIPT)

NOTE: The second requires rebuild of RedBoot.

RedBoot commands: http://ecos.sourceware.org/docs-latest/redboot/redboot-commands-and-examples.html

Optional (see above).

redboot/<version>/include/redboot.h
#ifdef CYGFUN_REDBOOT_BOOT_SCRIPT
EXTERN char *script;
...

redboot/<version>/src/main.c:
#ifdef CYGFUN_REDBOOT_BOOT_SCRIPT
# ifdef CYGDAT_REDBOOT_DEFAULT_BOOT_SCRIPT
    if (!script) {
      script = CYGDAT_REDBOOT_DEFAULT_BOOT_SCRIPT;
    }
# endif
...

Elad, start with any simple script or even with unknown for RedBoot
command:

cdl_option CYGDAT_REDBOOT_DEFAULT_BOOT_SCRIPT {
    user_value 1 { "blah\n" }
};

Then you will have

install/include/pkgconf/redboot.h:
...
#define CYGFUN_REDBOOT_BOOT_SCRIPT 1
#define CYGDAT_REDBOOT_DEFAULT_BOOT_SCRIPT  "blah\n" 

Yet another useful CDL option
CYGNUM_REDBOOT_BOOT_SCRIPT_DEFAULT_TIMEOUT
