I have been trying to digest the resources available for the EDMA controller for the OMAP-L137 included in the framework components (fastcopy and dmaXfer in the example folder). I am having problems even trying to build these examples much less try to follow the functions spread between a dozen different locations/tools/drivers.
The basic application I want is to create, without bios/os support, will utilize the EDMA to talk to both SPI ports (read/write to one and just write to another). The EDMA will utilize linking to loop the EDMA allowing for a self sustained continuous transfer on the SPI ports.
One thing that I can not find are references to actual register values or locations as seen in the DSP datasheets. Without register values the code is hard to follow. It would be nice to have an example like something found in the tests at:
http://support.spectrumdigital.com/boards/evmomapl137/revd/files/RevD_EVMOMAPL137_BSL.zip
and
C:\CCStudio_v3.3\boards\evmomapl137_v1\dsp\tests
Will the examples included in the framework so far help me at all? If not can I get some example coding which may? Has anyone actually successfully built the fastcopy example found in the framework using CCS 3.3 on windows? If so could tell me how?
