Hi, I am able to boot linux kernel 2.6.12 on ppc 8540, and also able to login too. But then i am unable to see any output when i say ls, mount,ifconfig etc. Only pwd and env seem to work Whereas if i boot with kernel 2.4.20 and with the same ramdisk which i used to boot 2.6.12, i am able to see eveything, ls, mount outputs etc.
I built the ramdisk image using busybox 1.2 This is the boot messages of 2.6.12 : ## Booting image at 01000000 ...
