LI-5M03CS mt9p031 Beagleboard-XM camera module in Ubuntu

Hi all,

I have two LI-5M03CS camera modules and I need to make them work in Ubuntu 12.04 with BeagleBoard-XM.
I downloaded Ubuntu kernel following the instructions in: http://elinux.org/BeagleBoardUbuntu#Building_Kernel

  • I ran build_dev.sh
  • Then I activated Device Drivers->Multimedia support->V4L2 sub-device userspace API (EXPERIMENTAL) menuconfig kernel option.
  • After this I activated Device Drivers->Multimedia support->Video Capture adapters->Encoders, decoders, sensors and other helper chips->Aptina MT9P031 support
    And then I continued compiling the kernel.

After the kernel compilation I installed the .deb packages, and then I runned:
sudo modprobe mt9p031
sudo modprobe v4l2_common

mt9p031 module is loaded, but no /dev/video0 device is created.

dmesg doesn’t show anything regarding this matter. This is an lsmod dump:
sudo lsmod

Please, could anybody give me a tip?

Hi,
I too followed the instructions mentioned on the elinux website but the kernel configuration menu does not contain Device Drivers->Multimedia support->Video Capture adapters
Instead, I could find
Device Drivers->Multimedia support->Sensors used on soc_camera driver
But still I cannot find mt9p031 driver option. I am not sure if I did something wrong or does the support not exist now.

Any help would be welcome.

It's still enabled by default in the v3.7.x branch of that repo.
Anything later is still broken for the omap3-isp driver..

Hi Robert,
Thank you for your response.
I am a little confused though. Do you mean that for v3.7.x, the driver is really baked into the kernel and that is why I cannot see it in the menuconfig option list?

I am relatively new to embedded linux and still trying to learn the ways so please be patient.

Thanks in advance,
-Kartik
