Sorry, I am having the same problem. I still am unable to control the
MUX to select the imager interface over the default tvp5146. The only
thing I do know is that, if you're using the EVM, you need to write to
the MSP430 (address is 0x25 according to the docs on
spectrumdigital.com) on the EVM through the i2c bus to control the MUX.
I just don't know how to do this.

Hello Anthony,
I was reading through the Davinci DM355 mailing list. I found your posts
on adapting video driver for an external decoder or an CCDC module.
I am trying to realtime streaming using DM355 and I would like to modify
the existing board to use either a standard definition decoder chip
which is cheaper and smaller - like TVP5150 or
high definition decoder such as TVP7002.
I am struggling to understand the VPFE driver architecture and things i
need to do to switch the mux to use imager data lines instead of onboard
decoder. Any suggestion from your side would be of great help.
