Hi,
I am running dvsdk4 on DM368 EVM board. My general use case works fine here. I found few test apps, in linux driver examples folder of dvsdk. Now I am using those test apps and trying to derive a new case out of it.
- tvp514x_ccdc_file.c provides below data path for Image/video. TVP-->ccdc-->ccdcOut-->DDR, in continuous mode.
- tvp514x_ccdc_prv_rsz_file.c provides below data path for Image/video. TVP-->ccdc-->prv-->rsz-->rszOut-->DDR,in continuous mode.
- prv_rsz_ss.c provides DDR-->prvIn-->Prv--->rsz-->rszOut-->DDR, in single shot mode.
All the above use cased works well, if you run individually. However, I am looking for an app, with path customized as below.
TVP-->ccdc-->ccdcOut-->DDR ----->(do some processing here)-->DDR-->prvIn-->prv-->rsz-->rszOut-->DDR.
I have few questions on that.
- Is it feasible?
- I observed individual/independent buses available for ISIF to DDR , RSZ to DDR and DDR to IPIPEIF. But When I try to run My above app, complete system hangs. I need to reboot the system. Why?
Appriciate your help.
