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.

Check that the platform file you're intending to use matches the compatible
field in the root node of the device tree -- and that said platform file is
actually being built.

I would probably remove the bcsr region. this was some cpld I believe on a=
reference board. with this dts it'll try to write to some hardware regist=
ers that do not exist or are not mapped to the same area.

[-- Attachment #1: Type: text/plain, Size: 7804 bytes --]
Hi Scott:
I am still stuck at Linux kernel booting in MPC8343EA based board.
I have disabled "Ethernet, PCI, USB, dma engines " in the *.dts file and
also in the kernel config.
I am using MPC8349emitxgp.dts ; enabled MPC8349ITX support in kernel config
also. In fact, I tried building MPC8349emITX; MPC8349MDS also. Same
behaviour!
With this, the kernel boots up (explicitly passing the DTB file and cuImage
NEVER worked) and hangs after
I am using Linux-V-2.6.27.18 and using powerpc-e300c3-gnu toolchain -
gcc-4.1.69-eglibc-2.5.69-1 to build u-boot-1.3.2 & linux.
With this, the kernel boots up (explicitly passing the DTB file and cuImage
NEVER worked) and hangs after printing
"Calibrating delay loop... 133.12 BogoMIPS (lpj=266240)"
With a few debug printks looks like the kernel hangs in
"cpu_idle" in --main/init.c
Any clues..?? HELP!!!
Please find the dts file and screen-dump below:
Thanks,
Junita

Try to find out what threads are blocked where.
There may also have been a problem transitioning to the normal serial
driver. Do you have an external debugger than can extract the log buffer?

Hi Scott:
After enabling debugging option from kernel (2.6.29) , here is the log.
We do have an external debugger(BDI). But soon after the crash happens,
looks like the core freezes and hence reading from any location in memeory
gives "SAP: Read access failed" error.
I have disabled PCI.
--Thanks,
Junita
