TDA4VM: Does SDK7.3 support 3840*2160 Camera

user5892527

Part Number: TDA4VM

We are bring up 8MP Camera(3840*2160), Deserializer output mipi, and we can see mipi signal by oscilloscope, but no udmaCQEvent event, no udmaCQEvent, and no csi error interrupt.

How to debug the issue?

Hi,

Couple of questions,

Is the lane speed configured matching with the sensor/deserializer output lane speed?
is the data type and virtual channel id matching?
is the number of lanes and lane polarity correct?

Regards,

Brijesh

We have get picture by mipi analyzer.

But Still can't dump picture by app_single_cam.

In "DRA829TDA4VMAM752x Technical Reference Manual", 12.7.1 Camera Streaming Interface Receiver

Support of:
– One 4MP camera -or-
– Eight 2MP camera streams

So, does TDA4 support 8MP Camera

And the same board, we bring up 1MP camera success, so hardware is OK.

Hi,

Can you please check if lane band speed (laneBandSpeed) is getting configured correctly in the file ti-processor-sdk-rtos-j721e-evm-07_03_00_07\vision_apps\apps\basic_demos\app_single_cam\app_single_cam_main.c? I think it was fixed in SDK7.3 release. If this is the case, can you please try changing it in this file?

Also could you please make sure to enable/start sensor/deserialzier streaming in the streamon callback only?

Regards,

Brijesh
