Technical discussions about the TI C6000 DSPs (including the c62x, c64x and c67x DSPs).
Hi, I use a C6713 DSPor and CCS 2.21. When using DSP/BIOS config, I found I can't set up DMA channel. If I right click "DMA_channel0" in "DMA Resource Manager", and choose "Properties", the "Open DMA Channel" checkbox is gray. If I insert a new dmaCfg in "DMA Configuration Manager", all options (except the "add comments" option) of the newly added dmaCfg are gray. Could somebody tell me why? Thank you. Xuchen
Got the answer, C6713 has no DMA. What a mistake;-) Xuchen _____ From: c...@yahoogroups.com [mailto:c...@yahoogroups.com] On Behalf Of yaoxuchen Sent: Sunday, July 01, 2007 8:54 AM To: c...@yahoogroups.com Subject: [c6x] Can't check the "Open DMA Channel" option in DSP/BIOS config Hi, I use a C6713 DSPor and CCS 2.21.

open the settings of CCS 2.0, and check if you really selected the C6713. You must have set another processor, that has no DMA. Check also that you use the XDS560 driver. Regards

Oh, Sorry. I mean C6713 has no DMA devices but EDMA devices. So I can check the "Open EDMA Channel" option but can't check the "Open DMA Channel" option. Thank you for your link!
