Hello,
I would like to use a the official raspberry camera for a personal
project.
This camera is using the CSI port of the Raspberry Pi (between the HDMI
and the Ethernet port).
I naturally looked at the openWRT Wiki to know how to enable a camera:
http://wiki.openwrt.org/doc/howto/usb.video
I selected the required packages in the kernel menu and also the module
"Broadcom BM2835 MMAL camera interface driver".
From my understanding, the GPU being closed sourced, a kind of api is
necessary for the kernel to access to the camera sensor. This API seems
called MMAL (Multi-Media Abstract Layer).
When the kernel tries to load this module, the module returns the error
"bcm2835-v4l2: error -1 while loading driver".
After some dig in the code, it seems that the function
"vchiq_mmal_component_init()" of the file bcm2835-camera.c is returning a
wrong answer.
With Chaos Calmer, this module is loaded smoothly.
Have you any ideas or suggestions about this issue?
Thank you in advance !
Le Savon Fou.
