Hi Members of linuxppc,
I'm working on XUPV2P board with Virtex II Pro FPGA device.
I written a kernel module for LED device. I got that module run successfuly on
ML403 board having Virtex 4 FPGA.I have not make any change in my source code,
because I don't feel any change is required.

Hi,
my processor is MPC8247, on Linux 2.6.11
in MPC8247 manual reference, the interrupt of DMA unit belonged PCI bridge.
that is different from SDMA and IDMA. through i do not know what 's the
different. heard SDMA is used to transfer between CPM and 60x. DMA is used
to transfer between 60x bus
thank you dave for your reply

With regards to your Oops: we sometimes find that, although a switch may
report a port being active, whenever
we try to discover what lies behind it, transfer errors occur that are
non-recoverable.
As a solution, on Freescale MPC8641D, we use a DMA transfer to perform a

All,
First off, we turned SPE off completely in our build - so we
could debug a much deeper problem that seems to be occurring
in our application (before we try to find a potential test
case for corruption of GPR registers).
We have had this problem for 3 weeks, and just recently have
come do

I have ported Linux-2-6-29 to my MPC8272 based board, very similar to the
MPC8272ADS. I am using a cuImage.
Things seem to be working ok except that I am not getting any FEC interrupts
(on IRQ5).
I see that I am transmitting ok.
Any ideas where the problem could be?

Recently , I'm busy with a project based on the main board - MPC8349EA. We use
a pcf8574 connected I2C bus. Now my task is programming to test I2C bus. I find
that file system contains the chip(pcf8574) module .And I add this module into
the kernel. But I find that system only registers the driv

According to the manual, it comes with 8 but can be expanded to 32. I
