DMA init done by SIMCOP LIB && M3 VIDEO crash

Iris Zhou

We used to work with DVRRDK3.0 on DM816x,now we are working with IPNC_3.5 on DM814x.

So we transplat iss of IPNC to DVRRDK3.0,on DVRRDK3.0,we meet a problem,CPIS_init will init EDMA handle,it means VPSS doesn't need to init edma itself,it just use the handle inited by simcop lib,and M3 VPSS work well,but we found M3 VIDEO crashes.

Is there any confliction in using edma between M3 VIDEO and simcop lib???

Or what changes do we need??

Intergrating ISS capture in DVRRDK is not simple. It is better to use IPNC RDK where this is supported.

If you want to continue debugging sOme things to check:

Check SYSTEM_VCOP_ENABLE

Check /dvr_rdk/mcfw/src_bios6/utils/src/utils_dma_common_cfg.c

has correct DMA channel assignment for M3 video and there is no conflict with c674 EDMA allocation,
