Hi There I'm about to write DSP/Bios drivers. My first driver is the DMA interrupt-driven low-level streaming device driver (example comes with spra802) My second driver should be similar, but communicate not over the ad535 codec. Instead of that only write and receive data to and from the MCBSP1. Both drivers should work with EDMA. is it possible easily to bind both drivers in a project and let them communicate? I simply commented out the things necessary for ad535 and changed the names for mcbsp0 to mcbsp1. I configured the mcbsp (hopefully right). but the EDMA interrupt never occurred. best regards andi

Andi, Since it sounds like you are just getting started, I'd recommend updating to the newer DSP/BIOS device driver model (LIO has been updated and improved to IOM model). Checkout the Device Driver Developer's kit or if you are just interested in writing a driver for DSK6711 then spra850.pdf. DDK is available at: http://dspvillage.ti.com/docs/catalog/software/details.jhtml?templateId=5154 &path=templatedata/cm/swdetail/data/perifdvr_ddk Thom -----Original Message----- From: feu_andi [mailto:] Sent: Monday, June 30, 2003 5:41 AM To: Subject: [c6x] driver mcbsp0(ad535) and mcbsp1 Hi There I'm about to write DSP/Bios drivers.
