DM36X EVM: How to capture / encode video from composite?

Hi,

It looks like the TVP514x (video decoder) driver is unable to communicate with the chip over the I2C bus.  Would you post the complete kernel boot log?

Thanks,

Chris Richardson

Hi Chris,

Please see the startup log (tell me if you mean to another log):

Hi,

Well it looks like the board info for the decoders is correct.  I haven't used the EVM for a long time and our board file is now a lot different than the EVM board file, so it's hard to come up with any suggestions.  I can say that we are using SD composite input just fine here and were also using it on the EVM, so it does work.

A search revealed the following thread: http://e2e.ti.com/support/embedded/linux/f/354/t/94157.aspx, which suggests that disabling the "TI DaVinci Key Scan" driver in the kernel config may help.  The probe seems to be failing anyways, from your boot log (the line is "dm365evm_keys: probe of 1-0025 failed with error -16").

Sorry I couldn't be of more help and good luck!
