I did and it worked! Thank you so much for pointing
out this key problem for me.Actually,I want to use
this UART for communicating with another module
instead of as serial console.But by now,it seems that
there are only demo serial console program for 16550
in both U-Boot and LINUX kernel.OK,anyway,I made the
good beginning under your help. Next step,I will try
to make some changes on exist program for my special
usage.
Thanks again!
Sam
