Hello,
I'm using the at91sam7x 256.

I can't understand, how to enable the debug unit. Of course, I have the examples but which program do I need, to see the printf or input the 0,1,2...?

Using the HyperTerminal shows no actions. (115200Baud, 7databits, no parity, odd, stop bits 2, xon/xoff)

Thanks for help.

Chris

Try the follow hyper terminal options:

baud: 115200 (you had that one correct)
Data bits: 8
parity: none
Stop Bits: 1
Flow Control: none


Thats how I have mine set up, although I am using the AT91SAM7A3. Might be the same though.
