I have integrated a BAYER - 720P sensor to Dm365(dvsdk4). Now I am using my custom app to capture some raw data from ccdc.
[wrote my application by refering tvp514x_ccdc_llopbac_mmap.c & mt9p031_ccdc_file.c or rather I would say this application is exactly same as mt9p031 capture application except resolution !!]
If run this application, it HANGS at "streaming started successfully" please refer below logs.
Capture Buffer 2 mapped at address 0x407a0000.
Q capture BUF 0---402b1000---1c2000
Q capture BUF 1---4052a000---1c2000
Q capture BUF 2---407a0000---1c2000
streaming started successfully
I have set the data path/pads as below.
CAPTURE/SENSOR ---->CCDC--->VideoNODe[fileDump].
Checked(probed) the clock, data, I2C lines of sensor. everything looks proper.
What all the possible issues whcih I may have to look/debug further?
After debugging for awhile I found that, videobuf_waiton() function in /drivers//media/video/videobuf-core.c return a error -EGAIN [-11]. What could be the possible issue? Where I am missing?
Thanks.
