Hello Scott,
I forgot to mention that I have less error if I use the existing device node
"spi" in the DTS file
# Start of error capture
Got device node from device tree
Got Virtual IRQ
PPC : interrupt hook failed (-22)
# End of capture
So it's able to access the device node and to map "vir
erface (is that true?).
Can you recommend any good hardware and software solution for that, if
possible running on linux (OSS?)? I don't need a "real" debugger
(maybe an interface to gdb), just something to write the flash, so
u-boot comes up.
Thanks for any help,
Albrecht.
Thanks guys for the info and pointers.

I have a Motorola (now Emerson) Prpmc800 board. I have a working
2.4.25 kernel that I can load from flash or TFTP, but I can't seem to
get a 2.6 kernel to load. I've tried 2.6.24 and an older ~2.6.16
kernel with no success.
I'm trying to use ELDK 4.2 with 2.6.24 kernel and building with the

If you don't have any code on the board then I can't think of how to write to
the flash unless you have a JTAG device. I use a BDI2000 to do precisely what
you're doing: write U-boot into virgin on-board flash on a design derived from
the lite 5200.
The significance of the debugger is that you

Hi Joachim,
We did not had a crash, but had some problem with assigning resources
for PCI bus on 8641D. Your issue may be related or not, I am not really
sure.
You might want to check out MSI patch. Currently this is already there
for few other FSL processors like 85xx, but not for 86xx.

Thanks Scott for the tip. I'll redouble my efforts to compare the code
in my older 1.1.2 U-boot source (that the board boots from) with my new
.dts and cuboot source.

Could you elaborate on exactly what you tried? Did you pass the GPIO device
tree node?

Hello folks,
we run a proprietary board with Freescale MPC8641D using U-boot 1.1.4 and
Linux kernel 2.6.23
First of all, we are no experts in PCIe-Bus handling and management.
We started with the problem that U-Boot was able to scan the devices
connected to PCIe-Bus where the kernel fails.
