[PATCH] ARM: OMAP: Make OMAP1 work again

[PATCH] ARM: OMAP: Make OMAP1 work again

[Dirk Behme]

[-- Attachment #1: Type: text/plain, Size: 353 bytes --]


In mach-omap1/mailbox.c the mailbox name is .name = "DSP"
while in plat-omap/dsp/dsp_core.c function  dsp_mbox_init()
asks for "dsp". This results in a strcmp() mismatch and then
OMAP1 system crashes due to NULL pointer. OMAP2 is correct,
there .name is "dsp". Correct OMAP1 name to "dsp" as well.

Bug? - OSK Frame Buffer Support in Kernel 2.6.18-omap1

[Sideleau, Scott R]

Hello,

When trying to build the 2.6.18-omap1 kernel with the frame buffer support
option for the OSK selected, the build fails while trying to compile
".../drivers/video/omap/omapfb_main.c" with numerous errors.

I selected frame buffer support as shown at the "OSK for Dummies" web site
(albeit without the "OMAP internal LCD controller support" option checked as
it apparently no longer exists)...

http://oskfordummies.hp.infoseek.co.jp/howto/lcd.html

Has anyone successfully built the 2.6.18-omap1 kernel with frame buffer
support?  Is my problem a known bug?  Any help is appreciated.

I am going to try to revert to a 2.6.14-omap1 kernel, but there are no
guarantees that the old build will resolve my problem.

Thanks, in advance.

With patch I sent some minutes ago most recent git works for 
me on OSK with frame buffer and Mistral LCD.

Do you use recent git? What are your errors?

I use

CONFIG_OMAP_OSK_MISTRAL=y
CONFIG_VIDEO_V4L2=y
CONFIG_FB=y
CONFIG_FB_MODE_HELPERS=y
CONFIG_FB_OMAP=y
CONFIG_FB_OMAP_CONSISTENT_DMA_SIZE=2
CONFIG_FB_OMAP_DMA_TUNE=y

Cheers

Hello,

Thanks for the reply, Dirk.

I was quite certain I was not using the latest Git, so I've spent most of the
day updating everything.  I grabbed the latest 2.6.18-omap1 kernel from the
repository (and put it in a completely new place) via:

git-clone git://source.mvista.com/git/linux-omap-2.6.git

I'm quite certain I have the absolute latest git right now.  I then chose the
proper frame buffer support via 'make menuconfig' that I then compared
against your list.  From your list, the following lines match in my .config
file:

CONFIG_VIDEO_V4L2=y
CONFIG_FB=y
CONFIG_FB_MODE_HELPERS=y
CONFIG_FB_OMAP=y
CONFIG_FB_OMAP_CONSISTENT_DMA_SIZE=2

The following lines simply do not exist in my .config file (even commented
out, as they should appear if I didn't select them):

CONFIG_OMAP_OSK_MISTRAL=y
CONFIG_FB_OMAP_DMA_TUNE=y

I just attempted another compile and it failed at the same point in
'omapfb_main.c'.  Here's an excerpt of the errors dumped to my terminal:

RE: Can't Boot - OSK Frame Buffer Support in Kernel 2.6.18-omap1

[Sideleau, Scott R]

Hello,

I was finally able to get a successful compile of the 2.6.18-omap1 kernel
with the help of Dirk Behme's config file (thanks again, Dirk).  Now, though,
the OSK is unable to boot the new kernel, but instead just hangs.  From my
console (as it has been running for the last half-hour)...

I wonder about the adresses used here. Do you followed

http://oskfordummies.hp.infoseek.co.jp/howto/flash_kernel.html

?

I would assume kernel at 0x40000 and start address/entry
point at 0x10008000. E.g.:

## Checking image at 00040000 ...
      Image Name:   Linux-2.6.11-omap1
      Image Type:   ARM Linux Kernel Image (umcompressed)
      Data Size:    1159328 Bytes = 1.1 MB
      Load Address: 10008000
      Entry Point:  10008000
      Veryfying Checksum ... OK

> Any ideas?  Any and all help/direction is appreciated.

For debugging, enable

Kernel hacking -> Kernel debugging -> Kernel low-level
debugging functions

(and temporarily apply patch in attachment, seems to be
necessary to work low level debugging properly).

[Sideleau, Scott R]

Hello,

Thanks again for working with me, Dirk.  :)

I wiped everything and started again, using the memory addresses from that
guide (I had been following a different one)... it still hangs.  Output is as
follows...

=====
## Booting image at 00040000 ...
   Image Name:   OE
   Image Type:   ARM Linux Kernel Image (gzip compressed)

   Entry Point:  10c08000
   Verifying Checksum ... OK
   Uncompressing Kernel Image ... OK

Starting kernel ...
=====

The Load Address and Entry Point have remained the same, though.  The rest of
the flash is empty as I manually erased it all.

Any ideas?

OOI do you have CONFIG_DEBUG_MUTEXES set? I've found on the E3 having
this set means that the kernel hangs on boot with no output whereas
disabling it results in an ok boot. I've been meaning to go back and try
and work out exactly what's going wrong but haven't got round to it yet.

I don't see that option in my .config at all, so it is not enabled.

Dirk Behme [dirk.behme@googlemail.com] wrote...

I re-built an uncompressed binary, at your recommendation.  After copying
this to the OSK, I was able to successfully boot to a point.  It was pointed
out to me that I would need to mount the rootfs to get it to boot any
further.

My uncompressed kernel image was 2.2-MB (2278208 bytes).  It was written to
flash at memory location 0x00040000 on the OSK.  That means the kernel ends
(after some hex arithmetic) at 0x0022c340.  It seems to make sense to me,
then, that I could drop the rootfs at 0x0022c341 since it is supposed to
start at 0x00240000 anyway.

I wrapped up a JFFS2 rootfs weighing in at 5.2-MB (5242880 bytes) and dropped
it in memory location 0x0022c341 on the OSK.  The OSK boots a little bit
further this time, but is giving some more errors I don't really understand.
Output is as follows:

I'm sorry, I meant 0x0026c341.  Please note the 6.

0x0022c341 was the size of the kernel, plus 0x00040000 yields 0x0026c341 -- a
memory location already beyond 0x00240000, the listed start location for the
rootfs.

RE: Can't Boot - OSK Frame Buffer Support in Kernel 2.6.18-omap1

[Sideleau, Scott R]

I re-compiled the kernel again with low-level debugging enabled and patched,
as Dirk Behme previously requested of me.

I game up trying to put the rootfs near the kernel in flash, so I moved it
back to 0x1000000, far away from everything.

The board will boot and appears to successfully mount the rootfs, but still
hangs awkwardly.  The output is quite large, so I put it in a pastebin...

Any ideas?

RE: Can't Boot - OSK Frame Buffer Support in Kernel 2.6.18-omap1

[Sideleau, Scott R]

Hello,

I noticed that after each attempt of running the kernel, the kernel would
turn up with a "Bad CRC Checksum" error.  I decided, on a whim, to try
starting over with flash protection enabled.  It appeared to get a bit
further (tried to start the Dropbear SSH server), but still fails in the end.

Output from my console is, again, quite large.  I do not know if it is of any
help in this troubleshooting, but I made it available for viewing at the
following pastebin...

http://rafb.net/paste/results/Dst2qf91.html

Any ideas?  Thanks, in advance, for any help/advice you can offer.
