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
