DaVinci



Texas Instruments Davinci line are a range of processors with tightly optimised DSP and peripheral hardware

Despite the marketing hype there are a number of issues users are falling into, a number related to the MontaVista Linux installed with the EVM. This wiki is intended to help reduce the duplication of effort that is currently occuring and suggest some common fixes (or at least highlite the most common mistakes!)

Anything you find here should be considered highly dubious and it is entirely your own responsibility for breaking your stuff.

(Most of these are stubs waiting for some nice user to help pad out)
