Hi All,
This is yogesh,we have a custom made board with
1)MPC5200B(with host bridge support)
2)PCI2PCI Bridge device from texas instruments TI2250 (PCI2250PCM)
3)DM642 dsp based processor
and other I/O devices like serial port,HDD interface,ethernet etc
we have successfully ported U-BOOT 1.1.3 and linux-2.4.25 where all
resources are working fine we where able to commnuciate form HOST to TARGET
and from TARGET to HOST using PCI2PCI Bridge where MPC5200B is acting as
HOST and DM642 is TARGET
Now we have migrate from 2.4.25 to 2.6.11.7 where booting is happining but
we have problem in PCI where we are not able to do host to target or target
to host commnuciation we have added some fixup code for PCI but found
nothing useful
can you please tell what could be wrong and what is the major difference
2.4.25 to 2.6.11.7 pertaning to PCI
find the attachment to the log files of both 2.4.25 and 2.6.11.7
please help out since we are struck with this problem for a long time.
when we tried 2.6.17.3 kernel source from kernel.org
we got the following log the kernel hangs after uncompressing
(LINUX-2.6.17.3)
