do you really have 32bit (24:8) register access for your 16550?

fa000010 : 00000100 0360f0ff 00000100 0360f0ff

..... That looks more like 8bit.

Please try #define CFG_NS16550_REG_SIZE 1

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
