 Hi All,

 I have one mpc8568 board using UART1 as the serial port.  The OS is
 Linux Kernel2.4.  If I use the polling mode driver of
 gen550_progress(), it works fine. However the printk() does not work
 after the console_init(). Anyone know what shall I change in the
 kernel to use UART1 as serial console? I assume the default is UART0,
 but I don't know where the value is set. I changed the CONFIG_CMDLINE
 to ttyS1, it does NOT work.

 Thanks for your help,

 Mike
