[ts-7000] Re: Where do I install a new kernel?

["Ray" <>]

Hi Frank, 
You are correct, the bootrom just kicks things off, the following link
explains a bit more what I am trying to get working.

http://www.embeddedarm.com/epc/fastboot.htm

The issue I have boiled it down to is that after doing a bootrom
update using the -s option as described in the above docs, the 
board fails to boot. Just hangs after the 3 dots. I am still working
through how to use the bootload (actually bootload_static).
