[Skyeye-developer] u-boot linux from nand

[Ray Chen]

Hi, all

I'm study how to boot linux image from nand based on s3c2410 and skyeye.
I have following steps of the reference article
http://tel.linuxfans.org/bbs/thread-182694-2-1.html

uImage is from "make uImage" in the linux-2.6.14 source code. I get
errors "SKYEYE:NumInstrs 299452156, mem_write_byte addr = c0010406 no
bank". Can anyone
tell me what to do next?? Thanks in advance!

Ray
