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

two things; I had better luck with the mpc8349mds (? don't remember exact file name) dts as opposed to the itx. I had to remove the bcsr section or else the kernel hung during initialization . also, your u-boot is not passing the correct kernel commandline:
"Kernel command line: root=/dev/nfs rw nfsroot=192.168.200.230:/nfsroot/rootfs i0IPIC (128 IRQ sources) at fdffc700"
you're trying to run a ramdisk and with tty I expect:
"root=/dev/ram rw console=ttyS0,115200 "
check your environment variable bootargs in u-boot

Subject: dts file for MPC8343EA
Hi
We have an MPC8343EA based custom board.
I am not able to get Linux up and running in this. No serial output to debug further.
U-boot shows correct 'bdinfo' & 'clocks' output.
inux hangs at machine_probe.
I doubt the DTS file in Linux. anyone has DTS file for MPC8343??
u-boot version - 1.3.2
linux-2.6.27
The board base files are drived from MPC8349Imtx-GP since we have the reference board in which we tested the linux image.

Eric,
1. I did try building with MDS configuration.
2. Removed BCSR section
3. Set u-boot environment variable.
The code boots up in the MPC8349 reference platform and not in the custom
board.
Also I am wondering why the cuImage would not give out any serial output
even, whereas I do see serial out with DTB file passed from u-boot?!!
