Actually, I don't believe that the TS-BOOTROM is sophisticated enough
to load and run the kernel. Is it? Normally the TS-BOOTROM just
initializes a few things, runs RedBoot, and RedBoot then loads and
runs the kernel.
So I thinks you may want to see if you can get RedBoot to load the
kernel from the SD Card, and then execute it.
I'm not sure if RedBoot recognizes the SD Cards. I know that on the
7200 it recognizes the CF card, and can load the kernel from there.
>From the RedBoot command line there is a 'disks' command that will
give a list of the "drives" it recognizes.
Unfortunately, the 'disks' command may not be compiled into the
version of RedBoot that comes pre-installed on the board, so you may
need to recompile RedBoot from sources.
But that seems like an awful lot of work. It might be easier to
compile a new kernel, install it into the flash, then have RedBoot
load & execute that one using the file system on the SD Card.
