Ning,
Well, AFAIK the serial console on the second UART (and second UART on
SCC4 as well) haven't been included yet to the community tree. To be
sure you can take a look in the 8260_io/uart.c where in rs_table
structure second entry should be {0, 0, PROFF_SCC4 ... Implementation is
not that hard, you need only make proper mentioned entry, enable
transceiver (BCSR+4), and program parallel port pins (take a look at
chapter 37 of MPC8272 reference manual, grep for SCC4).-- Regards, Vitaly
