Hi Chris, I think because your running your DMA output in a circular loop, the SPI peripheral sees it as one transmission, and therefore holds CS low during the entire transmission (i.e. forever). One trick you could do is use the MCPWM peripheral and run a PWM signal in parallel to your SPI output....
