Re: [ECOS] AT91EB40 wiggler JTAG programmer

[Ulrich Dahl <ulrich at elbomedie dot dk>]

Hi

Yes I press C, and it writes Continueing

I press Ctrl-Z and start "minicom -o", press enter some times and
absolutely nothing happens..

But I think it is because I have tried out the Atmel example code and
flashed the rom with it... It might be confused, who knows..

I am trying to get the JTAG interface to erase the upper mem part of the
flash but it doesn't seem to work... But there is still a little hope..

Best regards
Ulrich
