Re: [ECOS] AT91EB40 wiggler JTAG programmer

[Ulrich Dahl <ulrich at elbomedie dot dk>]

Hi 

Now something is beginning to come into view here..

Scott you are saying you tried to play with atmel software on the first
board, so did I and I flashed some code into ROM. And nothing other than
atmels code works..

Did you try atmel code on the other board as well?

I will try to reset the flash and see if that helps, I can clear a part
of the flash with the wiggler and windows... but nothing else..



And by the way, I am planning to get an expansion board made up with
extra flash and ram plus an ethernet chip (CS8900A most likely) mayby we
should stick our heads together to save some costs on the board
production. I have good contacts overhere to get it made
professionally..

Bests
