Hello Kang,

First of all, thanks for your help. I got the lastest version of
SkyEye from svn,
without modifying any kernel source Linux 2.6.20-rc4, but just skyeye.conf:

cpu:  arm920t
mach: s3c2410x

#physical memory
#mem_bank: map=M, type=RW, addr=0x20000000, size=0x01000000
mem_bank: map=M, type=RW, addr=0x30000000, size=0x01000000
#all peripherals I/O mapping area
mem_bank: map=I, type=RW, addr=0x48000000, size=0x20000000

now I can boot:
$skyeye -e vmlinux -l 0x30000000,0x0fffffff -c skyeye.conf

start addr is set to 0xc0008000 by exec file.

My question is why I saw several error messages  s3c2410x_io_read_word
and s3c2410x_io_write_word? How can I solve this? Thank you.
