at91sam9263ek can't establish USB connection with PC - laurisvdb - Jun 30 21:22:32 2008
Hi!!!
I can't connect to the PC with my at91sam9263ek
ATMEL AT91xxxxx Test Board doesn't appear in the taskbar notification
area neither the \usb\ARM0 option in the SAM-BA GUI Application
The first time I connected my board everithing went well, I installed
the drivers for the board and I got to use SAM-BA but suddenly it
stopped working.
I can't get anything from USB. I connected the board to another PC but
it never ask me for the dirvers and I don't see anything in the device
manager about the unit.
If I use serial debug port to connect, "no valid process ID found"
dialog displayed.
Actually when power up the board, "RomBOOT" can be seen on the serial
debug port.
any suggestion???
thanks!!!
Laura
