Please check your kernel config and/or

I feel the U-boot does not put 0xaf0 to r1 instead
0x7d9. Actually both
of them are listed in arch/arm/tools/mach-types.
Why does not kernel
match with 0x7d9?
7d9 is 2009:
sapphira
MACH_SAPPHIRASAPPHIRA 2009
which is a 'sapphira' platform, not a ti8168evm.
Whoever programmed
your boot loader stole some other platforms ID.
I suggest you check whether your version of u-boot
supports changing
the ID via a script. I don't know u-boot that
well, so I can't tell
you how.
for a short work around you can set the Environment Variable "machid" in that case uboot use the value of this Variable as mach id instead of the compiled one.
Oliver,
I set arcNumber but no use. What difference between machid and arcNumber?
CCing U-Boot mailing list ...
machid is what you use (if the company that made your board didn't mess up with it)
