Legacy mode gives a direct SDMA -> McPDM -> > twl6040 audio path so would be a good starting point for DMA testing. Sorry, what's ABE? Association of Business Executives? Association of Building Engineers? I had noticed that there's sound/soc/omap/snd-soc-omap-abe-twl6040.ko which needs a bunch of other modules, but even this doesn't cause any cards to show up. So, I'm guessing that the real answer to my problem is that there is no functional audio support on any OMAP board I have, and, therefore, I am unable to continue with the work which TI would like me to do. That's great. That's really bloody well great. I'm going to leave this in Santosh's hands to deal with, and arrange to get more complete and functional board support for any board that TI send me into mainline - for example, I _still_ don't have any working video output on the 4430SDP board. Utter crap. In fact, the only things that do work on the 4430SDP are serial and network. At least the 3430LDP has video output on its LCD. When will support for OMAP based platforms become a reasonable reality? When will people stop pissing around with utterly shit incomplete board support? I'm shelving further OMAP work until board support for these targets improves to a state where a reasonable amount of the platform is supported. Until that time I'm not wasting any more of my time trying to work out what I can do to assist OMAP along. -- To unsubscribe from this list: send the line "unsubscribe linux-omap" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
