I am having trouble using SAM-BA v2.6 to flash my AT91SAM7S256 eval
board.  The eval board works the demo program preloaded was running just
fine.

I performed the bootload copy by closing JP5 (TST), applied power, wait
10 seconds, power down.

When I run SAM-BA it ask for the communication port, to which I reply
"\USB\ARM0" and supply the board name as AT91SAM7S256-EK. Click OK. And
then I get a "communication error".

Is there any other software driver that should be loaded or anything?  I
found it curious that the communication drop down field did not list USB
just COM ports.

Thanks.

Joe

Hello Joe,

what board do you have, an original ATMEL board
or a clone?

Regards,

Michael

Michael,
I am using an Atmel AT91SAM7S-EK board. It has an AT91SAM7S256 part
installed.

In this case, I have no idea. I thought it was an other board.

Regards,

Michael

I discovered my problem.  When I would plug the USB cable into the
board. Windows would want to install a driver.  Before I was telling it
to cancel, well I let it install a driver (not sure of the filename...)
it started to work!

Nils,
I am running XP Sp2.  When I inserted the USB cable to AT91SAM7S-EK
board, I got the usual "found new hardware" dialog and I let it install
what ever driver it found because I didn't give it any help.  So if you
are running Windows XP just try to let windows find it's own driver.

Joe
