The most common problem with serial devices is not enabling CYGPKG_IO_SERIAL_DEVICES. Obviously you also have to include the CYGPKG_IO_SERIAL package too. Note that AT91 serial devices cannot be shared between diagnostics and serial drivers. So if you want to continue using diagnostics on a particular UART, you need to disable it for the drivers. -- Nick Garnett eCos Kernel Architect eCosCentric Limited http://www.eCosCentric.com The eCos experts Barnwell House, Barnwell Drive, Cambridge, UK.
