ml310 kernel2.6 booting problems

ml310 kernel2.6 booting problems

[Joachim Meyer]

Hi

I made an Ace file with my Kernel and load it with the Flash Card.
I made the Initial release CF image on the card and copied my ace file in an folder, from which I boot with the DIP-Switch.
If I used 
"console=ttyUL0 ,9600 root=/dev/xsysace/disc0/part2 rw "
in the Kernel config booting aborts like this:

what is the Problem here?
What should I consider when I configure the kernel, what when building an rootfs?

try root=/dev/xsa2
Also, the ',9600' is unnecessary with the uartlite.

You're probably missing the /dev/console device file

I'm also having some problem with my systemace file system. I'm working with
secretlab git, and I try to mount the CF card with xsysace and with xsa, but
in both cases it can't mount the rootfs:

Linux/PPC load: console=ttyS0,9600 root=/dev/xsa3 rw

Does this mean that I have configured incorrectly the file system options in
the kernel??
I have read that the solution to this is to change the DOS/FAT/NT Filesystem
option to the below configuration:

      <*> Second extended fs support 
DOS/FAT/NT Filesystems
       < > MSDOS fs support

  [*] Advanced partition selection                                
         [*]   PC BIOS (MSDOS partition tables) support 
I've already tested this configuration:

      <*> Second extended fs support 
DOS/FAT/NT Filesystems
       <*> MSDOS fs support                                            
       <*> VFAT (Windows-95) fs support                                
       < > NTFS file system support 
  [] Advanced partition selection                                
     

My CF card has the following structure:

Disco /dev/sdc: 521 MB, 521773056 bytes
16 cabezas, 63 sectores/pistas, 1011 cilindros
Unidades = cilindros de 1008 * 512 = 516096 bytes
Disk identifier: 0x00000000

Disposit. Inicio    Comienzo      Fin      Bloques  Id  Sistema
/dev/sdc1               1         400      201568+   6  FAT16
/dev/sdc2             401         500       50400   82  Linux swap / Solaris
/dev/sdc3             501        1011      257544   83  Linux

I'm also wondering if I should use xsysace or xsa, because I have search in
the file xsysace.c for the name of the device and It is named as xsysace. Am
I right, and should I use xsysace? Or this name isn't related with the /dev
file??
$ grep xsysace xsysace.c

        .name = "xsysace",
        ace_major = register_blkdev(ace_major, "xsysace");
                printk(KERN_WARNING "xsysace: register_blkdev() failed\n");
        unregister_blkdev(ace_major, "xsysace");

I'm going to reformat my CF card and test it,maybe the partition table is
corrupted, but fdisk is not saying anything at all.

Thanks

You're definitely not having a filesystem problem; it's a partition
table problem.  Either the partition table is corrupt or the kernel
doesn't understand the type of partition table, or the system ace
isn't able to read the CF correctly (hardware problem).

Re: ml310 kernel2.6 booting problems

[Joachim Meyer]

Thx for the answer

It's right, there is no /dev/console, but the MontaVista-Linux-kernel can =
fully boot with this rootFS, how comes=3F
Doesn't matter, I was going to make my own RootFS anyway, so can you give =
me an hint how I would
do this best=3F
I tried the Klingauf-Script (www.klingauf.com) with busybox, but I still h=
ave no console in my /dev/ and it doesn't work.
I tried out buildroot, but I was a little overstrained with the configurat=
ion and when I did "make" it aborted with an error message
after a long time of working
Then I tried ELDK. I read that I could use the Directory "<install-dir>/pp=
c=5F4xx/" as rootfs but when I go there and look inside=20
/dev I find only one entry:
prw------- 1 jogi jogi 0 2007-01-20 04:58 initctl
So this won't work, would it=3F

Which way would be the best for me to get an good RootFS easily=3F
If the answer would be buildroot can you give me a short summary which set=
tings are importent=3F
I read I can use my crosstool-Xcompiler, but I couldn't figure out how.=20

Greetings & Thx
Joachim

hmmm, I don't know.  The montavista kernel might be running a
different binary as the init process.  Compare the kernel parameter
lines between the two.

Creating a console device is easy:

$ mknod /dev/console c 5 1

Looks like you haven't installed ELDK correctly.  I recommend
rereading the instructions and giving it another try.  ELDK is a great
starting point.

Personally, I use buildroot, but you should start with ELDK to get things going.

Re: ml310 kernel2.6 booting problems

[Joachim Meyer]

Hi

My Linux runs finally. Thx again for the help.
But 3 Questions remain:

1. After mounting the rootfs there came an message, 
"fatal error, couldn't find modprobe in /lib/modules/2.6.24-rc3/..." or something like that.
so I changed the folder /lib/modules/2.6.19.2 to /lib/modules/2.6.24-rc3.
Is this a solution or will I get Problems with this?
Can I say ELDK that I have Kernel 2.6.24.rc3 ?
I only installed and ran the 2 scripts, like they say in the docs.

2. There came also something, that the it couldn't read the time or clock. Is it an error
or has the Board no clock?

3. I still need a network connection. Because of some special reasons
I prefer the ml310, so changing to a XUP would be the last possible solution.
Because of the Problems I had when I tried to compile the 2.4-kernel
(where the pci bridge works, I think) and can't find the proper 2.4 kernel-Version
to compile it successfully, theres only one solution, beside the XUP, left.
I need to bring up the pci bridge for the ml310.
I read at the mailing list this:
-----------------------------------------------------------------------------
I ended up using Secret Lab's GIT tree as my source archive, so I'll
let you know if I need to fix some code.

Hmmm... I'm not really ready to invest that much time into the PCI for ML-310.
--------------------------------------------------------------------------------
http://ozlabs.org/pipermail/linuxppc-embedded/2007-December/029211.html

How much work would it be (approximated), and do you think I can success (I'm a novice, like you know)?
Would you help me (Tell me where to start & what to do)?


Anyway I ,once more, wanna thank you, I wouldn't come so far, in that time without your help.

Hi Joachim,

I was also interested in getting the PCI to run on the ML-310.  I did
spend an evening trying to integrate a patch sent over by Stephen
Neuendorffer from Xilinx.  I managed to get everything to compile
(basically I fixed a few missing macros and had to search a bit to
ensure that the memory mapping was correctly ported).  Unfortunately,
when I tried the new kernel, I think that I must have messed something
up with the interrupt mappings (I am a newbie to PCI) and I had to
remove some interrupt mapping from Stephen's patch.

In any case, my ML-310 was booting the Linux kernel, but something was
not right and I did not get anymore printouts from the UART Lite.
Since I don't have the JTAG cable, I was stuck at this point with
little means to debug the system.  One day I'll spoil myself with one
of those platform JTAG USB cables...

I used Z-modem to transfer files to/from my workstation to my CF card
on the ML-310 and this was an acceptable compromise.

I'd still be interested in having the PCI bus working on the ML-310,
but now that I got my BEE2 booting Linux 2.6, its not such a big
priority for me.  Let me know if you have some success in that
direction.

Re: ml310 kernel2.6 booting problems

[Ron Sass]

Hello All,

I have a sidewise question related to this thread.  We have
several ML-310 and ML-410 boards.  At some point, we may need
PCI but right now it is not urgent so I am not ready to invest
a lot of time yet either.  I imagine that 2.6 + PCI would be
relatively similiar for both ML-310 and ML-410...

My question is this:  Would it make sense to have a Kernel
configuration something like "VIRTEX_PCI" and a platforms
"XILINX_ML4xx" / "XILINX_ML3xx" ... or create four platforms:

  XILINX_ML300
  XILINX_ML310
  XILINX_ML40x
  XILINX_ML410

I ask now because we are working on some device drivers for
the ML410 that may work on 40x and I wondering if I should
introduce a new ML410 platform option...

RE: ml310 kernel2.6 booting problems

[Stephen Neuendorffer]

Ron,

It might be better to start with the kernel from git.xilinx.com, which
already has an ML41x option.  The current version of EDK will also
generate support for ML410 with the PCI driver, if you are still using a
2.6.10-era kernel. =20

I've refrained putting the PCI stuff on git.xilinx.com, because any
non-trivial usage of it that I've tried has generated warnings.  On top
of that, the code has some interrupt values hardcoded in the ALI
southbridge code.  Since there is no way to have this code pushed into
mainline, I'm not terribly interested in encouraging any work on it,
either.  Perhaps since there is so much interest in this code, someone
would like to get it working in ARCH=3Dpowerpc?  I'm happy to provide =
some
handholding to get someone started.

Steve

Re: ml310 kernel2.6 booting problems

[Ron Sass]

Oops.  I should have looked at git.xilinx.com.  I've been using
secretlab's for a while and I saw xilinx site come up but never
took the time to investigate.  Even if it not mainline suitable
code and 2.6.10-era, I would be interested.  I'll explore in my
free time over the next couple of weeks and see what I can figure
out.

Thanks for the speedy response!

The whole CONFIG_XILINX_ML*** stuff will be disappearing as part of
the migration from arch/ppc to arch/powerpc.  Instead, the board
configuration will be described using a device tree file (dts).  Feel
free to add stuff in your local tree, but be prepared to migrate your
drivers in the next 6 months or so.

Cheers,
g.
