STK5200 pci_enable_device problem

STK5200 pci_enable_device problem

[Mustafa Cayır]

Hi all,

I am working on TQ STK52000 development board with TQM5200-AB cpu =
module. I am trying to use PCI bus and Local Plus Bus together. SM501, =
video chip is located on local plus bus and PLX9030 based pci device is =
on pci bus.

My pci driver is able to scan pci bus and find succesfully the pci =
device. After this point, pci_enable_device function returns following =
error:

PCI:  Device 00:18.0 not available because of resource collisions

Any help is appreciated.

Which ELDK and kernel do you use? I had the same problem on this board 
with a PLX9054 based PCI card on a 2.4.25 kernel. I switched to the 2.6 
kernel and the 4.1 ELDK and the card was scanned correctly.
But keep in mind that the linux PLX drivers do not work out of the box 
with a big endian platform like the MPC5200. Although there is a 
BIG_ENDIAN flag in the makefiles there are still some places left in the 
driver code which have to be patched (the parts with int64 adresses).
It's not so easy to compile the PLX drivers on the 4.1 ELDK because of 
missing headers in the ppc architecture. I managed to build the drivers 
for the 2.6.19 kernel and I was able to work with the card except the 
DMA routines (still working on this issue).

Hope this helps. Bye,

WHy don't you use the arch/powerpc configuration, then? Note that the
STK5200 has never been supported in a  2.6  kernel  with  a  arch/ppc
configuration.

Because I found at least a lite5200 configuration in the 4.1 ELDK 
(2.6.19.2 kernel) in the ARCH/ppc architecure. With ARCH/powerpc I only 
had a few configurations for other modules and I wasn't able to build a 
running kernel for the TQM5200 (maybe my fault).
Is there support for the TQM5200 and the STK5200 with ARCH/powerpc in 
newer kernels? I'm still using the 3.1.1 ELDK for the TQM5200 as it have 
everything I need and I don't need to use the PLX card in this board 
(although it would have been nice if I got it working...).

You will find many completely unsupported board configurations in the
kernel.org tree, too. The fact that somethign  is  present  does  not
mean anything.

The TQM5200 / STK5200 are supported in our linux-2.6-denx  tree  with
an  arch/powerpc  configuration; also lite5200b. Note that - like all
MPC5200 support in the 2.6 kernel - this is all work in progress.

Hi ,
i use 2.4.25 kernel and eldk 3.1.1 on TQM5200 board. i tried denx 2.6.19 kernel to port on TQM5200 but i couldn't.
Did you port 2.6 kernel on TQM5200? Did pci device start working succesfully after porting 2.6 kernel to TQM5200 board.

Current top-of-tree in our git repo has been tested with a Intel
EEPRO100 network card in the ST5200's PCI slot. It's working.

Hi,

i build Linux-2.6.22-gbcfc8d37 kernel lastest kernel from denx git for the board (STK5200 with TQM5200-AB).
ELDK 4.1 version is used.

make mrproper

make uImage

It hangs on after  following line
  Uncompressing Kernel Image ... OK

Any idea will be appreciated.

I encountered exactly the same problem. Using U-Boot 1.2 with Kernel 
Linux-2.6.22-gef92f1d7 and a TQM5200S-BD module on the STK52000. I tried 
to modify some kernel settings but it always stopped booting at the 
"Uncompressing Kernel Image ... OK" line.

Probably it does not hang, but you just don't see any console output.
Eventually  you  just  forgot  to  set  the  correct  console  device
(/dev/ttyPSC0) or console speed.

Also, you need a recent version of U-Boot (for  example  99c2fdab  or
later).

Try something like this:

=> tftp 200000 /tftpboot/tqm5200/uImage
=> tftp 400000 /tftpboot/tqm5200/tqm5200.dtb

Please note that the device tree we have at the  moment  is  for  the
TQM5200 only and does not include support for the TQM5200S.

But probably you just had the same problem - missing or  bad  console
device specification.

I checked this. I think the TQM5200 is really hanging after the ...OK 
because I have activated the telnet server and normally I'm able to 
connect to the device after booting via ethernet. No ping, no telnet. 
With an older 2.6.19.2 kernel this was O.K.

I'm using U-Boot 1.2.0-gbc2b9c33-dirty (Feb 22 2007 - 09:53:14). Is that 
recent enough? (I don't know exactly what you mean with "99c2fdab", is 
this the second number after "1.2.0-"?)

Maybe the problem is the missing tqm5200.dtb file. I have booted the 
kernel without it (just bootm 200000). Does the kernel need this file? I 
found a tqm5200.dts file the the kernel sources, but the device tree 
compiler (dtc) seems not to be in the 4.1 ELDK. Do I have to install 
this compiler and build the appropriate dtb file?

In older kernels it was O.K. just to uncheck the SM501 drivers in the 
kernel configuration. Has this changed?

No, that is *way* too old.

The number after the "-g" is the (initial 8 digits of the) git commit
ID. You can use this to identify  a  spoecific  version  in  the  git
repository.

Yes. An arch/powerpc kernel will not run without a proper device tree.

Yes, this is correct. dtc will be included with ELDK 4.2.

As mentioned above, with arch/powerpc you always need a  device  tree
blob.

Hello Oliver,

My problems continue, could you summarize your steps to bring up the board?
which u-boot version is used?
how build tqm5200.dts file?
did you test pci bus?

Thanks.

Did you try the linux-2.6-denx repo on our server? Note  that  you'll
need a somewhat recent version of U-Boot for device tree support.

RE: STK5200 pci_enable_device problem

[Mustafa Cayır]

Hi,

i get the latest kernel sources and u-boot sources directly=20
from the git archives from www.denx.de.

My kernel version is Linux-2.6.23-rc5-gaa8ddd08
u-boot version is U-Boot 1.2.0-ge251e00d-dirty

i use dtc compiler with following command:
dtc -O dtb -o tqm5200.dtb -b 0 tqm5200.dts

TQM5200 doesn't boot and gives following error. Any help would be =
approciated.

Thanks a lot.

You should get the latest kernel sources and u-boot sources directly=20
from the git archives from www.denx.de.
Only use the native git protocol, not the HTTP git protocol.
E.g. "git-clone git://www.denx.de/git/linux-2.6-denx linux-2.6-denx"
Build u-boot with the configuration for your board. If your card is NOT=20
a 66 MHz PCI-card, then undefine CFG_PCICLK_EQUALS_IPBCLK_DIV2 in the=20
u-boot configuration to get a 33 MHz PCI bus.
Build u-boot and flash it to the module. Then install the dtc compiler=20
from the git archive (git://www.jdl.com/software/dtc.git). Do NOT use=20
the tar archive on the web, it is out of date. Compile a dtb file out of =

the tqm5200.dts file you find in the kernel sources.
Build the kernel with tqm5200_defconfig.
Boot your module and load the kernel and the dtb file in u-boot. E.g.=20
"tftp 200000 mykernel" and "tftp 400000 mydevicetree.dtb".
Don't forget to change the serial console output. On the 2.4 kernel the=20
internal mpc5200 uarts had the name ttyS0/ttyS1/ttyS2. On the 2.6 they=20
are called ttyPSC0 up to ttyPSC2. So type in u-boot
"set addcons 'setenv bootargs ${bootargs} =
console=3DttyPSC0,${baudrate}'"
"save" (don't forget the single quotes in line above!).
Boot now with "bootm 200000 - 400000".
Now it should boot fine.
I've tested a Korenix Jetcard 1404 (Oxford 16mPCI954 chip) with this=20
kernel and it runs fine. I had no luck with the 2.4 kernel as it failed=20
to give the card an interrupt.

Mustafa,

It would have been nice, if you would *NOT* repost my private mails I'd 
send to you on the mailing list. At least you could have cut off my 
footer from your mail!
As I thought that it is not of general interest I wrote directly to you 
- but not too see my mails back again on the list. That's really bad style.

Bye,
