yeah, sounds like. I was so optimistic that Linux is kind of primary OS for
any ppc board  when I choosed this board :-)

I was just using the elf image, instead of uimage.
'6501A8C0.img' is refereing zImage.img which is Linux elf image.
It looks to me that the bootelf command interprets ELF format corrently.

As you sugested, I also made uImage and used bootm to boot it.
But no luck. Here is the log.

=> setenv bootargs "console=ttyS0,19200 console=/dev/ttyS0"
=> tftp 0x100000 uImage
Waiting for PHY auto negotiation to complete.. done
