ARM S3C6410 kernel boot
 

I am working on ARM S3C6410 device now. The problem is first 256KB of NAND was broken. I am trying to boot with SD card, uboot works. What I want to know is as following.

- Can I boot kernel from SD card without NAND?
- Can I run uboot from SD card, and then boot kernel from non-broken area of NAND?
I am a newbie. I hope guru's help.
