Changes in kernel configuration.

Hi
I have successfully run DVSDK_4_00 on my Leopardboard 365. My question is how to change the kernel configuration in order to disable tvp7002? I have disabled it in make menuconfig:
Device Drivers->Multimedia support->Video capture adapters->Encoders/decoders and other helper chips. Next I have run make. But still during the boot, kernel tries to write to the tvp7002 registers.

This is the boot output which I get:

Were you able to get this resolved? I took the same steps here, but still same error. I cannot decode or encode any video. I am getting an error saying unable to initialize display. I just want to play out my composite port.

Thanks

I switched to RidgeRun SDK. It works very well.

Is it free? Or do you HAVE to purchase the Professional SDK?

It's free only for evaluation purpose. If you want to use it in commercial product then you have to buy licence.

Marian,

Just disabling the tvp7002 in kconfig and building wont work. TVP7002 is a subdevice decoder used for vpfe, why do you want to disable it?

If you are sure you don't want the tvp7002 decoder, than you have to remove the code related to tvp7002 from platform and board file of dm365 entirely to remove this device support.

the files are,

1: arch/arm/mac-davinci/dm365.c

2: arch/arm/mach-davinci/board-dm365-evm.c

Hopefully this should solve your problem.

Regards,
