Thanks for your fast reply.

But I am not sure if I understand the problem.

printk() is used long before the CPM UART driver is initialized (or am I
wrong).

So how is printk done before this driver is started, i.e. rs_8xx_init is
called?
And can I output some string to the console without using the CPM UART
driver?
