booting 2.6 kernel on ML403

booting 2.6 kernel on ML403

Hello Ameet/Ming!
   
  I am running linux kernel 2.6 on a ML403. Your posts on the list was extremely helpful and saved a lot of time. But i have ran into a number of issues and need your help. I have described both the scenarios.
   
  Problem 1:
  I followed the steps described in http://www.linux.get2knowmore.com/2006/06/30/quick-guide-linux-26-on-xilinx-virtex-ii-pro-boards-part-i/
  After the kernel boots towards the end i get a failure - unknown-block(0,0)

  [    3.012128] VFS: Cannot open root device "sda2" or unknown-block(0,0)
[    3.088465] Please append a correct "root=" boot option
[    3.150933] Kernel panic - not syncing: VFS: Unable to mount root fs on unkno
wn-block(0,0)
[    3.249891]  <0>Rebooting in 180 seconds..
   
  On the linux partition of my CF card i created the following block device files
  # mknod -m 660 console c 5 1
# mknod -m 660 sda b 254 0
# mknod -m 660 sda1 b 254 1
# mknod -m 660 sda2 b 254 2
# mknod -m 660 sda3 b 254 3
  mkdir tts
# mknod -m 660 0 b 4 64


  But the result was same as above. 
  What should be my default bootloader kernel arguments?
  console=ttyS0,9600 root=/dev/sda2
  or 
  console=ttyS0,9600 root=/dev/xsa2
  or
  console=ttyS0,9600 root=/dev/xsysace/disc0/part2 rw
   
  I am confused. How do we determine the device name of the CF card?
   
  I have 2 partitions on my CF card - Partition1 is DOS FAT16 partition, Partition2 is Linux with ext3 filesystem.

  
 
  Here is the full log of the serial terminal:
Linux/PPC load: console=ttyS0,9600 root=/dev/sda2

  - After including the network driver and sysace driver in "make menuconfig" and generating the zImage and booting the board the kernel hangs.

  I suspect the xparameter addresses are incorrect. Which parameter should i modify in the xparameters_ml403.h?

Note: my driver creates device xsa and not sda. so create xsa, xsa1, 
xsa2, etc. in /dev of your CF card instead of sda.

please check: this should be a character device. Hence use:

yes! root=/dev/xsa2. This is the right root parameter.

which patch did you apply? For TEMAC... apply the following patch: 
http://www.cs.york.ac.uk/rtslab/demos/amos/xupv2pro/patches/linuxppc-2.6.17.1-sysace-1.2-after-TEMAC.patch

Hi Ameet,
  Thanks for the instant reply. I changed root parameter to xsa as you suggested root=/dev/xsa2. But i still get the same failure.

  Yes, i have applied *only* after-TEMAC.patch. But looks like it blows away the configuration and results in kernel hang.
   
  Any further suggestions on where i should look at.
   
  regards.

Please could send me all the boot messages until the point where it 
stops. This will help me better identify the problem.

Pradeep,
   What you have pasted is only part of the messages displayed. I can't 
tell anything from this apart from you 'root=' option. It would be nice 
if you could paste the entire log of the boot messages right from 
'loaded at: xxxxxxx  xxxxxxxx' to 'Kernel Rebooting in 150 seconds'.

Hi Ameet,
   
  As soon as i apply the sysace driver and temac drivers and copy the xparameters_ml300.h (from EDK) to xparameters_ml403.h all i get is this... meaning kernel hangs after displaying "Now booting the kernel".
   
  When i disable sysace and TEMAC drivers, the system goes further till "root=" option and then tries to "Kernel Rebooting in 180 seconds". Yesterday i tried root=/dev/xsysace2 rw and creating block device files in /dev of the CF card. But it ran into the same problem.Is there a sysace driver patch that i can apply without applying the TEMAC driver patch? 
   
  So far i was using the EDK 8.1 SP2 (latest) which has the IP core TEMAC version 3.00. Now i downgraded to EDK 8.1 to get the version 2.00 (please see John Bonesio's post). 
   
  I thought the first step is to get the sysace driver running before applying the TEMAC drivers.

  thanks very much!
  Pradeep

Hi Pradeep,

I have experienced this before. But in my condition, I applied both ACE and 
Temac patches. Ameet said it's a problem of the kernel and the kernel just 
lost the configuration information. So just "make proper" and reconfigure 
your kernel and recompile it. In my condition, it helps. I don't know if it 
is useful to solve your problem. Just try it.

Yesterday i tried root=/dev/xsysace2 rw and creating block device files in 
/dev of the CF card. But it ran into the same problem.Is there a sysace 
driver patch that i can apply without applying the TEMAC driver patch?

Don't try root=/dev/xsysace2. In Ameet's driver, he defined as xsa2. So 
just keep consistent with the source code. 

Also, in his website, there are patches which are used without Temac. They 
are not labeled with -after-temac. 

>   So far i was using the EDK 8.1 SP2 (latest) which has the IP core TEMAC 
version 3.00. Now i downgraded to EDK 8.1 to get the version 2.00 (please

I am using TEMAC 1.00. The 3.00 version is totally different with 1.00. So 
I don't know if it is one reason about your problem.

Re: booting 2.6 kernel on ML403

[Pradeep Sampath]

[-- Attachment #1: Type: text/plain, Size: 4922 bytes --]

Ameet,
  I was able to get the system to work today with your Sysace driver patch and was able to boot the ML403 with the correct 'root=' option. But the kernel crashes with a "Oops: machine check, sig: 7 [#1]". (I have 'nt applied the TEMAC patches yet)
  It appears that the xparamater definition file genearted using EDK 8.1 does not map correctly with the driver and it looks like i need to further downgrade the EDK to 7.1 and re-generate the BSP. I am attaching the console logs and xparamater file. please ignore my earlier reply.
   
  thanks
  Pradeep

It looks that some errors still exist in the parameters you passed to 
"root=". Please double check it, or post it in the maillist for deep

Hi Ming,
IIRC, you are or were using the TEMAC driver along with my System Ace
driver, isn't it? Does my driver patch ***-after-TEMAC.patch work for
you? I ask this because Pradeep is having some problems using it (see
Problem 2 in his email). Could you please update on this?

Thanks,
-Ameet

Re: booting 2.6 kernel on ML403

[Ming Liu]

Hello Ameet,
I am using that driver very well now. There is only one problem. It seems 
that the driver for TEMAC only support Gigabit Enet, not 10/100/1000M 
adapted. But because I want to use the Gigabit enet, I don't care that. So 
it's OK, at lease for 1Gbit/s.

So I don't think Pradeep's problem is caused by Temac. I still suspect that 
he didn't pass a right parameter to "root=", just like what I posted 
before.

Ming

[-- Attachment #1: Type: text/plain, Size: 3338 bytes --]

Hello Ameet/Ming,
   
  First of all really appreciate your inputs on this... 
  Problem 1 :
  I was using the factory shipped compact flash as is which comes with a DOS FAT16 partition and a linux 83 partition with ext3 filesystem. I tried it on 2 factory shipped CFs and its the same behavior - . When i plug-in the CF card reader to the linux box it always reads it as "sda" and in the linux2.6.17.1/Documentation/devices.txt - sda is the device file for SCSI disk devices. Wonerding how you guys configured the root option as "/dev/xsa".
   
  Now i re-formatted my CF, created a ext2 filesystem using busybox-1.1.0 like the BYU instructions. Created 2 partitions on CF card 1. FAT16 partition & 2. linux partition and then created 1. dos file system using mkdosfs and 2. linux ext2 filesystem using mke2fs.
   
  But the problem still persists and i get "Please append a correct "root=" boot option :"
  :(
   
  Problem 2: After i included the TEMAC driver and sysace drivers, the kernel just hangs. I thought i'll fix problem 1 before i get to problem 2... 
   
  With your help i am getting the confidence that i can make this all work!
  thanks once again.

xsa and sda are nothing but the device name registered by the driver. It 
is not related to whether the device is a SCSI or not. Since I wrote the 
SysAce driver, I decided to name it as xsa (as opposed to the original 
Monta Vista xsysace). Thus, all the partitions on this device will be 
named xsa1 for the first partition, xsa2 for the second and so on.

When you access your CF card in your Linux PC, the driver names the 
device as sda. Thats all... theres no much difference. Hope you got the 
point.

cheers,

It is fairly easy to mangle the TEMAC driver for any fixed rate you
want. I added a spd value to the device data, set it to whatever I want
in the initcode, and
changed the SetSpeed () call to use the device data value instead of a
constant.
That was a 2 min kludge. At some point it needs real autonegotiation -
which should not be too hard.

RE: booting 2.6 kernel on ML403

[John Bonesio]

[-- Attachment #1: Type: text/plain, Size: 5110 bytes --]

Hi Pradeep,

 

If you are using the MontaVista/Xilinx driver for sysace for linux 2.6, the CONFIG_CMDLINE item in .config should have

    root=/dev/xsysace2 rw

in it. From the text below it's not clear what driver you are using. If you are using a different driver, you may be able to search for

    #define MAJOR_NAME

in the source code of the sysace driver. I believe that will indicate which device name you should use in the CONFIG_CMDLINE.

 

As you probably already know, the '2' in '/dev/xsysace2' refers to the partition number it should use - partition 2 in this case.

 

For Problem 2: Do you see any error leds light up on the board? It's possible that the drivers you are using for one or both of those cores is not meant for the version of the cores you are using. The core most likely to be suspect is the TEMAC soft core, as that has changed recently. Even though you are using the hard TEMAC core, there is a soft wrapper around it to connect it up to the bus and what not. This soft wrapper has changed from version 2 to version 3 not too long ago. While the TEMAC driver that MontaVista has (and I believe posted to this mailing list) is for version 2 of the soft TEMAC core.

 

Hope this helps,

 

- John

When i plug-in the CF card reader to the linux box it always reads it as "sda" and in the linux2.6.17.1/Documentation/devices.txt - sda is the device file for SCSI disk devices. Wonerding how you guys configured the root option as "/dev/xsa".

 

Now i re-formatted my CF, created a ext2 filesystem using busybox-1.1.0 like the BYU instructions. Created 2 partitions on CF card 1. FAT16 partition & 2. linux partition and then created 1. dos file system using mkdosfs and 2. linux ext2 filesystem using mke2fs.

 

But the problem still persists and i get "Please append a correct "root=" boot option :"

:(

 

Problem 2: After i included the TEMAC driver and sysace drivers, the kernel just hangs. I thought i'll fix problem 1 before i get to problem 2... 

 

With your help i am getting the confidence that i can make this all work!

thanks once again.

RE: booting 2.6 kernel on ML403

[John Bonesio]

[-- Attachment #1: Type: text/plain, Size: 4496 bytes --]

A quick amendment to my previous email:

The device name you should use in the CONFIG_CMDLINE  "root=..." can be found in the routine call to register_blkdev() in the driver source code. The first parameter to register_blkdev() is the major number of the device. The second parameter is the name of the device, as in /dev/xsda2, or /dev/xsysace2. This second parameter will contain just the 'xsda' or 'xsysace' in it, and it may be a preprocessor constant defined earlier in the file, such as #define MAJOR_NAME "xsda", but it might not be a constant either. It depends on the code.

 

Hopefully this clears things up a bit.

 

- John

Hello Ameet/Ming,

 

First of all really appreciate your inputs on this... 

Problem 1 :

I was using the factory shipped compact flash as is which comes with a DOS FAT16 partition and a linux 83 partition with ext3 filesystem. I tried it on 2 factory shipped CFs and its the same behavior - . When i plug-in the CF card reader to the linux box it always reads it as "sda" and in the linux2.6.17.1/Documentation/devices.txt - sda is the device file for SCSI disk devices. Wonerding how you guys configured the root option as "/dev/xsa".

 

Now i re-formatted my CF, created a ext2 filesystem using busybox-1.1.0 like the BYU instructions. Created 2 partitions on CF card 1. FAT16 partition & 2. linux partition and then created 1. dos file system using mkdosfs and 2. linux ext2 filesystem using mke2fs.

 

But the problem still persists and i get "Please append a correct "root=" boot option :"

:(

 

Problem 2: After i included the TEMAC driver and sysace drivers, the kernel just hangs. I thought i'll fix problem 1 before i get to problem 2... 

 

With your help i am getting the confidence that i can make this all work!

thanks once again.
