Memory Cache Usage on DM6437

Could you be a bit more specific on what you want to do with the cache on the DM6437? For the most part on the DM6437 and other C64x+ based devices you would use the BCACHE API from within DSP/BIOS to handle cache configuration and coherency, this API is discussed in section 2.2 of SPRU403 available below. Some of the examples included with the DM6437 software package utilize the BCACHE API, if you could specify what operation you want to do perhaps we could point one out for you, or at least explain how the API would be used.

I´m following the User Guide SPRU862a but it still not working correctly....

What specifically isn't working?  Do you think that the cache isn't turned on, or are you having coherence issues?  Please clarify your question so we can help.

how you make sure they didn't work?see the cache contrler,or other way?
