I have to set boot parameters "bootargs=root=/dev/ram console=ttyS0,230400", if i want to get output whose baud rate is 115200 when booting Linux. U-Boot 1.1.2; linux-2.4.21-crus-1-4-3; edb9315; Can anybody give me a bit advice?

Both are ancient versions; the problem is most probably in that old 2.4 kernel. Please update to the latest versions of U-Boot and Linux.

You may want to change bootargs to "root=/dev/ram console=ttyS0,115200" if you want a 115200 baud console. -Michael
