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 ## Booting image at ffa00000 ... Image Name: Linux-2.4.20-pre7ncsd1 Image Type: PowerPC Linux Kernel Image (gzip compressed) Data Size: 634729 Bytes = 619 kB = 0 MB Load Address: 00000000 Entry Point: 00000000 Verifying Checksum ...

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!
