I have big problem with my app. I'm using dm642 evm (Texas Instruments), and I need to use both video and audio input (in rf5 environment) , but I can't make them work together. I've added dio codec driver for aic23 audio codec and gio video(fvid interface) driver in dsp/bios module (i've used .cdb file from rf5 audio example and modyfied it to match my needs) but when i'm trying to run my app it fails on fvid_alloc command, or if i comment it on one of scom_open's coommands . When i'm using .cdb from rf5 motion detection example then sio_create from audio codec faileds to run. Could you give me some advice what should i do ,or better send some example code with both audio and video codec drivers

There's a lot of pin muxing on the DM642. The McBSP is muxed with one of the video ports so make sure you're not trying to use both simultaneously.
