Forum Post: RE: RidgeRun SDK Hangs booting custom dm8168 board

Hi Inigo, 

     Part of the problem that you are seeing is that your SDK has V4L2 support enabled so the initialization script that loads the firmware and insert the kernel modules needed is trying to insert the V4L2 capture module. This module will look for the TVP7002s that are normally in the EVM, I suppose that those are not in your custom board.

First, you can verify that you are having this problem in:

tvp7002 2-005d: tvp7002 found @ 0x5d (OMAP I2C adapter)
omap_i2c omap_i2c.2: controller timed out
omap_i2c omap_i2c.2: controller timed out
omap_i2c omap_i2c.2: controller timed out
omap_i2c omap_i2c.2: controller timed out
omap_i2c omap_i2c.2: controller timed out
tvp7002 2-005d: TVP7002 read error -110
tvp7002: probe of 2-005d failed with error -110
ti81xxvin ti81xxvin: Error registering v4l2 subdevice
Error while running '/etc/rc.d/S00coprocessors'.

If you don't need the V4L2 capture driver then go to $DEVDIR/fs/fs/etc/init.d/coprocessors and comment the line that inserts the module:

#modprobe ti81xxvin

Or just open the make config menu

make config 

and go to 

Proprietary software  --->

and disable:

[ ] Enable V4L2 capture capability

then close and save, and finally:

make 
make install

this will load the OMX firmware instead of the V4L2 firmware and it won't try to mount the V4L2 capture module.

If you need V4L2 then you will have to create the drivers for your video decoders or if it is FPGA you need to configure the capture driver to don't call the TVP7002 and just configure the video that you are going to expect in your inputs.
