APPRO IPNC RDK 3.0 How to change the sensor readout resolution?

Ron Shpasser

Hi, I'm trying to set the sensor readout resolution to 1280x960. In order to do that I configured the following registers of the MT9J003 (APPRO IPNC DM8127 Board) as follows:

============================

Source file: issdrv_mt9j003_config.h

struct: SensorConfigScript

x_addr_start = 674

x_addr_end = 3235

y_addr_start = 418

y_addr_end = 2339

x_output_size = 1280

y_output_size = 960

==========================

Source file: issdrv_mt9j003Api.c:

function iss_mt9j003Create()

line_len_pck = 2300

frame_length_lines = 2322

coarse_integration_time = 1000

============================

Source file: multich_stream_CaptureDisplay.c:

pCameraInstPrm->sensorOutWidth = 1280;

pCameraInstPrm->sensorOutWidth = 960;

The rest of the registers were left as is.

While running a minimal usecase with camera and display links and a single stream for a moment at the very beginning I could see maybe a single or a couple of frames on the display and then the display went blank. It seems that the m3vpss gets stuck.

The same usecase worked perfectly with the 1920x1080 resolution before the changes.

Please Help,

Ron.

Ron Shpasser,

Reason for this behaviour might be wrong configuration done in capture driver.

In your use case, Capture driver & iss configurations seems to be missing. Configuring ISS registers properly should solve the issue.

Thanks,

but it seems that the problem is more interesting, while playing around with different values for:

x_output_size

y_output_size

I can see that "x_output_size = 1280" does not crash the m3 if I use for y_output_size value greater than 1050.

Any suggestions?

Thanks,

Ron.

Any suggestions for exploring the issue ?

Thanks in advance,

Hi Ron -

Did you ever figure this out?

I'd also be interested in any solutions to this problem.

I will need a resolution of 1600x1200.

Thanks,

Mechi

No, I haven't,

anyway I would recommend to setup your sensor resolution so it will be at least 1600x1200 and then set the OutWidth

and OutHeight parameters according to the final resolution(crop).

Best,

Ron.
