[U-Boot-Users] UART doesn't work

Hello all:

Does anybody have experience in Marvell5182? I meet a uart issue on Marvell5182. Athough there are two UARTs on the demo board, I can only use UART0, the second UART can't be used, I do the same settings for UART1 as UART0, but It seems that UART1 still doesn't work, So I write the UART1 TX register directly on the U-boot command line, while using oscillograph to test if there are any output singals, from the oscillograph , The UART1 doesn't have any outputs. I don't know why, anybody can tell me what to do? By the way, I have opened all the possible macros in the include file.

Thanks in advance!

With kind regards, Robert Xia
