Hi Eric, I am building the linux kernel V-2.6.27 based on MPC8349miTXGP dts file. I am still not able to boot the cuImage.
But, I see serial outuput from kernel when I try to boot with <kernel> <ramdisk> <dtb file> Still the kernel hangs after "Dentry cache hash table entries: 32768 (order: 5, 131072 bytes)". Any clues ..?? We have DDR2 in this board and we are initializing it in U-Boot. Please find the screen dump below: Thanks, Junita Screen shot: =========== u-boot> bootm 0x2000000 0x3000000 0x4000000 ## Booting image at 02000000 ...
