Help required for TVP5151 on Overo

Help required for TVP5151 on Overo

[Francesco Marletta]

Hello to everyone,
I'd like to know who have used the TVP5151 video decoder with the OMAP3
Overo module.

I'm trying to have the processor to capture the video from a TVP5151
boarda, but without success (both gstreamer and yavta wait forever the
data from the V4L2 subsystem).

Thanks in advance!

Hi Francesco,

Yesterday I sent a mail asking about similar behaviour in another
OMAP3 board [1], I'm starting to think that OMAP3 ISP is broken in
latest kernel versions.

I hope someone give us a solution.

Regards,

Carlos

Hi Carlos,
thanks for your response.

I've read your message on permalink.

I'm not sure the ISP is broken, or at least it may be broken but it can
be fixed.

I'm trying to work the tvp5151 board described in [1], the author
states (and told me) that it was successfull in using that board, using
a patch that he also publish, but my board is not working (using the
same patch set). Maybe there is something different in my kernel, even
if the version is the same? 

I'm going to try applying the patch by hand, to check if there is
something different respect the source that the patch is made from.

It will be useful to me to have a kernel (with modules) that works with
that board, this way I could check if the problem is in the hw or in
the sw.

I'll continue to try.

Regards
Francesco

For what it's worth, I've successfully used that tvp5151 board with a Gumstix 
Overo using the mainline kernel. Changes required to the OAMP3 ISP driver have 
been pushed to mainline. Some changes were required to the tvp5151 driver too, 
some have made it upstream, but I haven't had time to clean up and submit the 
rest of the tvp5151 modifications.

I've pushed the patches to

	git://linuxtv.org/pinchartl/media.git omap3isp/tvp5151

Hi Laurent,
I'll check the patches you indicated on 
	git://linuxtv.org/pinchartl/media.git omap3isp/tvp5151

Which version of the kernel are these patches for? 

Regards
Francesco

Do you know that, if you clone the above tree and checkout the 
omap3isp/tvp5151 branch, you will get a Linux kernel source tree with complete 
history and a Makefile that contains the version number ? :-)

Yes, I know that... I was just asking to have a "memo" on the email.

Hi Laurent,
I'm finally started working on this problem... but the code from the git 
repository you specified don't compile:

make: *** [drivers] Errore 2

I cloned the repos with:

git clone git://linuxtv.org/pinchartl/media.git linux_omap3isp_tvp5151
cd linux_omap3isp_tvp5151

Choosed the branch for tvp5151 with:

git branch tvp5151_for_overo  remotes/origin/omap3isp/tvp5151
git checkout tvp5151_for_overo

Then configured the kernel with:
         make mrproper
         make ARCH=arm omap2plus_defconfig
         make ARCH=arm menuconfig

And finally compiled as stated before.

Maybe there is a special branch that I should use?

Regards,
Francesco

Hi Laurent,
I'm trying to use the kernel of the linuxtv repository, omap3isp/tvp5151 
branch,but the kernel don't starts... can you, please, send me the 
kernel command line that you have used?

Also, have you used device tree ?

Francesco

I'm afraid I haven't kept the .config file around. I might also have rebased 
the working branch without testing the result, so it might just not work on 
3.18-rc4. I'm sorry not to be able to help you for now.

No, I was using legacy boot. The OMAP3 ISP driver doesn't support DT yet.

Hi Laurent,
thanks for your reply... I'll disable device tree usage.

Also, I'll try to use a previous kernel (3.17) hoping it works.

Francesco

Help required for TVP5151 on Overo

[Francesco Marletta]

Hello to everyone,
I'd like to know who have used the TVP5151 video decoder with the OMAP3
Overo module.

I'm trying to have the processor to capture the video from a TVP5151
boarda, but without success (both gstreamer and yavta wait forever the
data from the V4L2 subsystem).

Thanks in advance!
