I would like to use SCC3 as second console, and use SMC1 as first console. I ported denx kernel 2.4.3-pre4 into my 860 board. when I compiling, checked SCC3 for UART option in MPC8xx CPM option. SMC1(ttyS0) is connected to my linux box COM2, SCC3(ttyS1) is connected to COM1.
What's the kernel output for the serial ports? Please send me your kernel boot messages!
After booting, in COM2 echo 1111 > /dev/ttyS1 result is shown in SCC3(ttyS1). so far good. but, COM1 port don't any receive keyboard key.
Please define what you mean by COM1 and COM2. How did you test this?
In /arch/ppc/uart.c I modified CONFIG_SERIAL_CONSOLE_PORT for SCC3 console #if 1 #undef CONFIG_SERIAL_CONSOLE_PORT #define CONFIG_SERIAL_CONSOLE_PORT 1 #endif
If in your configuration SCC3 is the second entry in rs_table[], then this should work.
