Hi Charles, I'm not sure what you try to accomplish, so I'll try to answer your question in two ways.

So you just only want to use 1 UART namely port 3 of you CPU? If this is the case you can start fiddling around with drivers/serial/8250_au1x00.c and also have a loog at include/asm/mach-au1x00/au1000.h If you just want to have your serial console on UART port 3 instead of port 0 you have to do a little bit more. First you need to tell yamon (the bootloader I expect you to use) to use UART port 3 instead of port 0 and then you just boot the kernel with the console= option. See Documentation/kernel-parameters.txt for more information. Hope this will help. Otherwist try to explain a little bit more thoroughly what you try to accomplish. Good luck! -- $ cat ~/.signature Freddy Spierenburg <freddy@xxxxxxxxxxxxxxx> http://freddy.snarl.nl/ GnuPG: 0x7941D1E1=C948 5851 26D2 FA5C 39F1 E588 6F17 FD5D 7941 D1E1 $ # Please read http://www.ietf.org/rfc/rfc2015.txt before complain!
