Can someone pl tell me how I can boot my WIZ device from SD card ?
If I put kernel image & rootfs image on SD card, can I boot with it ?

The kernel needs to be named 'uImageUP'.
Thanks, I have couple of more questions,

What partition type should I use for uImageUP, ext2 or fat ?
do I need to use any specific version of u-boot for mkImage utility to convert zImage -> uImageUP ? pl tell me the arguments to be used for mkimage
How to debug kernel booting from SD card, Is there a way to view kernel boot message's on wiz LCD or over USB ?
where can I find pre-built uImageUP to begin with ?
