U-boot garbled output

Installing and Using OpenWrt
1

Hello,

I am using buspirate to connect to UART on a WRN2000v5

Everything boots just fine. I get garbled output during U-boot. I attempted all baud rates from 300 - 115200 8N1. Output after U-boot is good. Would really like to know what is going on; I did manage to grab the env from mtd0

bguthrie@LinDesk01:~/images/_ActiveMtd0.bin.extracted$ strings 3AA4 | grep -i console
bootargs=console=ttyS0,115200 root=31:02 rootfstype=jffs2 init=/sbin/init mtdparts=ath-nor0:32k(u-boot1),32k(u-boot2),3008k(rootfs),896k(uImage),64k(mib0),64k(ART)

any hints on where to look for the issue?

Regards

the bootargs is the command line passed down to the kernel when booting.

if you install uboot-envtools, you can fiddle around with the uboot env settings from within openwrt.
