[U-Boot-Users] Need help booting linux on 8265 eval board

[
]

Hi,
  I have problem  booting linux on 8265 eval board. when I boot the linux 
kernel, the board be dead. the registers look like 

to be some default values(use powertap pro). I try u-boot1.1, ppcboot1.1.5; 
linux kernel 2.4.4 2.4.18 2.4.20.

(1)about kernel
vim Makefile, arch=ppc CROSS_COMPILE=ppc_82xx
vim arch/ppc/platforms/ads826x.h, IMAP_ADDR=0x04700000 BCSR=0x04500000
then make mrproper/make ads826x_config/make oldconfig/make dep/make pImage
(bd info struct is quite same between uboot and linux) 

Is there anything I had ignored?

(2)let's see!(I add some "printf" to display values, "console=ttyS0,9600" 
is added)
=> bootm ffa00000 ffc00000

## Transferring control to Linux (at address 00000000) ...

then the board is dead and the LED(FCC link) coruscate .
(I have modified clock calculations for this board. it's the reason?) 
any ideas? thanks a lot!
