Sorry about this, you will have to change the code. Someday, I have to finish up a better UART driver. You are the first person I know that is trying to use this as a UART. SMC2 is the first thing to disappear when using the parts for other data communication protocols or interfaces, so custom software tends to assign these for other purposes. I seldom see anything but SMC1 used for a UART, so making the driver better hasn't been high on the list...... -- Dan ** Sent via the linuxppc-embedded mail list. See http://lists.linuxppc.org/
