Hi ,

I am using RDK2.8 and EVM8168.

I want to integrate my algorithm in c674x. So I intend to move the data from DDR to c674x's L2 by EDMA.

Could you tell me the steps about how to do it?

Thanks !

Best Regards!

you can choose a case for your reference like multich_progressive_vcap_venc_vdec_vdis.c

Hi Jack,
I choose the case multich_progressive_vcap_venc_vdec_vdis, and refer to SWOSD.
I want to know something about how to use DMA to move video data from DDR to DSP internal memory L2.

Thanks!
Best Regards!

pls refer to function Utils_dmaxxx() like Utils_dmaOpen()

the related function could be found under ./dvr_rdk/mcfw/src_bios6/utils/src/utils_dma_dsp.c

the related usage could be traced under ./dvr_rdk/mcfw/src_bios6/

sorry the above is for rdk 3.0

pls refer to function Utils_dmaxxx() like Utils_dmaInit()

the related function could be found under ./dvr_rdk/mcfw/src_bios6/utils/src/utils_dma.c

the related usage could be traced under ./dvr_rdk/mcfw/src_bios6/
