Its seems that using SPI Bus 1 and EDMA is not possible.
Spi 1 wont work unless the following Section in the dm355,c file is commented out. which ALSO causes video encoding to Fail. This make EVEN having a SPI1 useless if you are going to use the processor to capture / encode video. what sense does that make?
Encode demo started.
