<p class=MsoNormal style='margin-bottom:12.0pt'>Hi Eric,<br>
<br>
I am building the linux kernel V-2.6.27 based on MPC8349miTXGP dts file.<br>
I am still not able to boot the cuImage.<br>
<br>
But, I see serial outuput from kernel when I try to boot with <kernel>
<ramdisk> <dtb file><br>
<br>
Still the kernel hangs after "Dentry cache hash table entries: 32768
(order: 5, 131072 bytes)".<br>
<br>
Any clues ..?? We have DDR2 in this board and we are initializing it in U-Boot.

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