there is a mini_demo example in the dvsdk of dm648. and in the readme file,
The video and audio device drivers for the DM648 EVM require that the external
muxing on the EVMs be set to correctly router the audio and video signals prior
to loading and execution. The GEL file supplied with the DVSDK software and/or
EVM packaging should provide the functionality to do this. If the external
muxing is not correctly setup on the EVM, the application will hang during the
DSP/BIOS initialization.
I've compiled and loaded the demo, but I cannot see any output printed when running.
could anyone explain what the muxing is, and can I bypass this. I only want a pure I2c control.
