Re: Solving U-boot problem

[Munro Biswal <munro.biswal@xxxxxxxxxxxxxxxx>]

Hi, Thiago,
I tried it this way for n times using n ways (i.e using n functions)
But the kernel somehow didnt pick it up from uboot when i issue bootcmd
Moreover, when i use bootm , it gives me "bad magic no." at that memory 
location.
What could be the reason for the boot arguments not being passed properly?
