Compiling Grub for DOC2000

Compiling Grub for DOC2000

[Frank Oltmanns]

Hi all,

I'm trying to run Linux (to be exact: RT-Linux) from a DiskOnChip. It's
already booting from NFS. I've got a Kernel (2.4.18) with build-in MTD-
support. I can mount/access the DOC when booting NFS. So far everything
is allright.
Here's my problem:
I want the whole thing to boot without NFS from DOC. I want to use grub
to get it work, but I can't even compile grub. This is what I did:
  1) I patched grub-0.92 with the mtd-patch
  2) I ran aclocal (everythings fine so far)
  3) I ran automake (Version 1.6.2)
Now I'm getting some strange Error-Messages (see below), and I don't
know what to do. I also tried to run autoconf and make afterwards.
Autoconf (Version 2.5.3) works fine, but make aborts.
Does anyone know what to do?

Thanks in advance
  Frank Oltmanns

Hi Frank,

I've seen these errors with the newest GRUB patch -- I think the latest patch 
may be against the CVS version of GRUB, rather than 0.92.

I've had good luck patching GRUB 0.92 with the 2002-05-30 patch at:
http://savannah.gnu.org/bugs/?func=detailbug&bug_id=505&group_id=68

Regards,

Mark

The copyright assignment got sent, and I've had a reply from the FSF. 
Hopefully it'll get merged soon.

It's the autoconf/automake change.  These now require CCAS and CCASFLAGS
variables instead of AS and ASFLAGS.  The June 2002 MTD patch at the
savannah link you've mentioned will change those in Makefile.am's as
needed.  I advise to apply the patch against the post July 2, 2002 version
of GRUB if you need serial port console at boot time.

Thank you all... It's working fine now. But I got some new problems.
1) With grub on my DoC, I can't boot from diskette anymore (I want to use
Etherboot)
2) My root-filesystem on DoC is not being mounted. I did the following:
      doc_loadbios grub_firmware
      nftl_format /dev/mtd0 90112  (since my firmware is 89792 bytes)
      fdisk /dev/nftla  (created 1 partition)
      mke2fs /dev/nftla1
   copied the files from my root-diskette to nftla1
   When I reboot, grub starts so I can enter:
      kernel (dc0,0)/boot/bzImage root=/dev/nftla1
      boot
   The kernel is being loaded and uncompressed. My DiskOnChip (and its
partition)
   is found, but when it should say: "INIT: version x.xx booting" there is
nothing.
   If I enter:
      kernel (dc0,0)/boot/bzImage root=/dev/fd0
      boot
   everything works fine...

I browsed through the Mailing-list, but I can't find anyone, who had the
same
problem. I hope someone can help!?

TIA
  Frank

This can probably be solved by changing this line in stage2/stage2.c

                    is_opened = find_config(0x80);

to

                    is_opened = find_config(0);

You may need to specify a multiple of 16 KiB as a start of NFTL layer in
case your erase block size is 16 KiB.  Make sure the /dev/nftl* drivers
weren't activated or were unloaded when running nftl_format.

>       fdisk /dev/nftla  (created 1 partition)

I believe it is required to reload the MTD NFTL driver between nftl_format
and any subsequent actions against /dev/nftl*.  Since my kernel has MTD
NFTL driver compiled in, I need to reboot.

Check out 

    http://lists.infradead.org/pipermail/linux-mtd/2002-June/005240.html

for detailed instructions.

My erase block size is 8KB (I'm using a 8MB DiskOnChip 2000), so this
should be no problem. I also tried an offset of 98304 anyway, but this
didn't change anything.

Sorry, I forgot to write, that I did reboot my system.

This is a nice Howto! I wish I had found this earlier. It could have saved
several hours. I did everything as described in this howto, but I still
can't
boot from DoC.
As I already wrote, the kernel is loaded from DoC (using GRub) but I
can't use the root-filesystem, which I have copied there. I CAN use
root-FS on NFS or FDD. I also do have acces to my DoC when I boot
with root-NFS.
I absolutely don't know what to do. Here is what is "dmesg" said after I
booted from NFS. Perhaps someone can tell me, what went wrong.

Remove the bogus invalidate_device() from the mtdblock_release() function

I did, but nothing happened.

Here is what I get, when using DoC as root-fs (debug-level 3) after the

Bah. Do what I mean, not what I say. 

Which, in this instance, means:

	Remove the bogus invalidate_device() from the nftl_release() 
	function in drivers/mtd/nftlcore.c

Sorry.

Yeah! That worked! Thanks a lot! I don't what I really did, but it
worked!
