[U-Boot] tftp not working for larger rootfs image

Thanks for reply...!

No idea how to do it. Is there any way, I can directly load the data to 
NAND through tftp or any other command?

I have tried boot to linux, and i am using nandwrite utility to flash the 
root file system. There also it hangs up after some time.
nandwrite writes from offset 0 to 2880000. Then it gives "Unable to handle 
kernel paging request at virtual address 01000000" error (kernel panic). 

Any help would be appreciated.

Thanks & Regards,

You could flash your rootfs.jffs2 directly to NAND and mount it from 
there, or if you have access to the FEC you could mount your rootfs via 
NFS.

Can't you use one of these approaches instead?
