I heard through the grape vine that you are considering using NuttX. I don't want to influence your decision, but if the decision is final, I would like to offer any support to the project that I can give.
thanks a lot for your feedback and assistance, it is very much appreciated.
I have a c5 DSP bridge driver somewhere around on my backup disks as well. I never released it into NuttX because there was never any need. Perhaps that could be useful now.
These DSP bridge drivers present interfaces to load programs into the DSP and to support an integrated, seamless messaging system between the ARM7 and the DSP.
The DSP interfaces differ from chip to chip and the drivers that I was referring were targeted for uClinux. However, if that is something you are interested in, I would be happy to do the port a driver and integrate DSP messaging with the NuttX messaging.
The DSP/ARM interface on the Ti Calyspo is very much defined by the mask rom code in the DSP. I think it is extremely GSM specific, and we already have full support for it in our existing osmocom-bb code... so I don't think we would be able to base this on anything existing.
