Re: AT91EB40 wiggler JTAG programmer


Hi

WOUW, that was an extremely fast response... Thanks

My main problem is; That I can download redboot to ram via the serial
cable and Angel monitor, but not execute it...

With the wiggler I can acces both the flash and the CPU, but not
download, only read the contentse...

So you see, I have some life but it is not nearly enough to get going..

Thankyou for your help

Ulrich
