Hey all,
I've been playing a bit with my AT91SAM7X-EK (AT91SAM7X256) development
board from Atmel and doing the whole flash, verify, run dance. It seems
that the verify image may be a bit broken. For some reason, it keeps
kicking the target into the run mode when I tell it to verify. By the
looks of the debug output, it has to do it, but for some reason it
thinks the board isn't halting although I can see that the board isn't
actually doing anything. The PWM program just makes some LEDs dim in
and out, so I can see when it isn't running. Other than that, the SAM7
flash stuff seems to work really well. I ran through some tests to make
sure I could write and read different things both from telnet and GDB,
so I think the "new" driver should be good for the AT91SAM7x256. I've
included my steps and the level 3 debug output for the verify_image piece.
