Linux Drivers for DaVinci

V.Faul

We are starting a new project and will be using the 6467.  We are thinking of using the SPI interface.  Does the Linux OS, which is included in the DVSDK, have drivers that allow developers to access the DaVinci specific hardware (in my case the SPI)?  If not, is there a repository of open source Linux drivers for DaVinci chips?  Or am I destined to repeat the development that someone else has surely done.

    Yes, the DVSDK does come with a variety of drivers, primarily that exercise the hardware on the DM6467 EVM board, this includes a SPI driver for accessing the SPI memory on the EVM which could be adapted to your particular SPI application.

    Now that I'm actually ready to start writing SPI code I need some more direction.  I searched in the DVSDK folders for a header file (and library file) that would allow me to call the SPI routines in order to setup and use the SPI, but couldn't find anything.  Where do I start?  Thanks in advance for your help.
