booting vlx linux on DM6437 without CCS

I compiled the linux version of Virtuallogix, it boots and works perfectly.

My only problem is that in order to boot it requires CCS to load the kernel on the DM6437. I just connect CCS to the board, reset it and load the program.

Now I would like to load it either from the NAND memory or through the serial interface.

I downloaded the spraag0d software and tried to generate the ais uart image.

It does not boot. So I'm wondering how do you load it to the DM6437?

    ok, but I wouldn't like to used a nand memory to boot each dm6437 I have on the board, because of price.

    I was wondering, is there a way to emulate what CCS does by uploading the program to the evaluation board through JTAG with some GPIOs? It's fast, it works and I could avoid the nand memory.

    To be more precise: I have a board with a dm6446 and several dm6437s. They are connected through an ethernet switch and I have an FPGA. What I would like to do is being able to connect some GPIOs of the dm6446 to the dm6437s trough the FPGA so that I can program each dm6437 and the let all the chips communicate over ethernet.

    Ideas?
