AM5726: DMA collateral or sample applications

Christian Alford

Part Number: AM5726

Hi,

Quick Question:

Is there some documentation or sample app that can be used to help implement the DMA process on the AM5726? I have a customer working to get this up and running and would like somewhere to start if possible.

Hi Daniel,

In linux kernel sources, there is a dmatest.c driver, which can be enabled through menuconfig or tisdk_am57xx-evm_defconfig.
Documentation about dma in linux kerne is available in the Documentation/dmaengine/ folder. The dts settings are described here:
processors.wiki.ti.com/.../Processor_SDK_Linux_DMA
See the TI EDMA serial binding information link.

Best Regards,
Yordan
