Do you know the root file system builder RFSB? See http://git.denx.de/?p=rfsb.git;a=summary > U-Boot 1.1.4 (May 20 2008 - 16:49:25) This is a very old version. It does not have any device tree support. Consider updating. > => setenv bootargs console=ttl0,19200,root=/dev/ram,load_ramdisk=1 You must not use commas to separate arguments; This should be setenv bootargs 'console=ttl0,19200 root=/dev/ram load_ramdisk=1' Please RTFM! > The system uncompresses and recognizes the kernel and the rootfs, but > fails because for some reason, it's trying to load the root fs via NFS, > even though I thought I told it not to do that.
