Hi Brijesh,

My software version is:
PDK-RTOS :processor-sdk-rtos-j721e-evm-08_06_00_12
PDK-LINUX:processor-sdk-linux-08_06_00

data_flow:

1920x1536 YUV422_8 * 2 ---> max96792A - - -> CSI1

We now have 2 60fps cameras connected，The data_land of 60FPS is 864Mbps/lane.

max96792A deserializer rate set to: 1800 MHz

When the image is set to
CSIRX_LANE_BAND_SPEED_1350_TO_1500_MBPS, the graph is working, but the camera is working at 30FPS.

When CSIRX_LANE_BAND_SPEED_1750_TO_2000_MBPS,

./run_app_multi_cam.sh gets stuck after running:

app_run_graph_for_one_pipeline: frame 1 beginning, pipeline:-2,line:1264

app_run_graph_for_one_pipeline: frame 2 beginning, pipeline:-1,line:1264

In order for two 60FPS cameras to work properly, what should our CSI rate be set to?

Looking forward to the expert's reply, thank you.

Regards,

Barry

Hi Brijesh,

This is when configuring CSIRX_LANE_BAND_SPEED_1350_TO_1500_MBPS, the camera only works at 30FPS, and the performance prints:

At this time, 2 cameras are connected, each with a frame rate of 60FPS.

Hi Berry,

But in this case, there are a lot of frame drops, Maybe, this is why graph is not running at correct speed.

[MCU2_0] 180.911628 s: Channel Num | Frame Queue Count | Frame De-queue Count | Frame Drop Count | Erro|
[MCU2_0] 180.911707 s: 0 | 1639 | 1637 | 1992 | |
[MCU2_0] 180.911841 s: 1 | 1639 | 1637 | 179 | |

There is no other error reported by the capture, so most likely, CSIRX is able to receive data at 60fps.

But in the graph performance, capture is only one running slower.

NODE: CAPTURE1: capture_node: avg = 32851 usecs, min/max = 73 / 86440 usecs, #exec5

Are you using enough number of buffers in the capture node? This could be one reason why capture is dropping a lot of frames and so running slower.

Hi Brijesh,

thank you for your reply.

1). We found that only more than 30 FPS after running is related to enable 2 displays to send superframe code in the multicam demo.

So we rolled back the code and only enabled 2camera in the multi demo. After running, the frame rate could reach 60, but the Frame Drop Count kept increasing. I tried increasing the value of CAPTURE_BUFFER_Q_DEPTH. The Frame Drop Count improved but still increased.

The following is 'P' when the buffer has not been changed:

#define CAPTURE_BUFFER_Q_DEPTH (4) #define APP_BUFFER_Q_DEPTH (4) #define APP_PIPELINE_DEPTH (7)

2).

According to the camera bandwidth requirements, the deserializer rate is set to 1800 MHz. When trying to set the CSI to any value greater than CSIRX_LANE_BAND_SPEED_1350_TO_1500_MBPS, it will get stuck after running: (CSIRX cannot get the data)

log:

app_run_graph_for_one_pipeline: frame 1 beginning, pipeline:-2,line:1264

app_run_graph_for_one_pipeline: frame 2 beginning, pipeline:-1,line:1264

When set to CSIRX_LANE_BAND_SPEED_1350_TO_1500_MBPS, the graph runs, and the frame rate is 60 accompanied by Frame Drop.

We would like to ask the experts:

1.What should be set to csi_laneBandSpeed?

2. What is the cause of the Frame Drop problem? What needs to be done?

Looking forward to your reply.

Barry

1). We found that only more than 30 FPS after running is related to enable 2 displays to send superframe code in the multicam demo.

Sorry, did not get this statement. Do you mean two displays are causing the issue? What are these two displays?

Yes, if there are two independent displays/outputs, running asynchronously, there could be issue, but increasing the number of buffers should have helped in this case, because it gives enough margin in case of the error. Are you seeing any other node running slower? Like any other node taking more than 16ms? then graph will eventually slow down and capture will start dropping frames.

Are you enabling deskew calibration sequence in the deserializer output? It is required for the lane band speed higher than 1.5Gbps.

Hi Brijesh,

thank you for your reply.

The DESKE description of each TX in the deserializer is: DESKEW_INIT[7:0] and DESKEW_PER[7:0]

Whether we enable one of them or both, capture can only run when CSIRX_LANE_BAND_SPEED_1350_TO_1500_MBPS.

1. Should we enable one of DESKEW_INIT and DESKEW_PER or both?

2.What should be the value of csi_laneBandSpeed in image?

Looking forward to experts’ help, thank you

Barry

Hi Barry,

Sorry i am not familiar with this deserializer, so can't help much in the deserializer configuration.

From the CSIRX perspective, CSIRX does not support periodic de-skew calibration, so it needs to be available at init time and it is mandatory for the lane speed more than 1.5Gbps.

Regards,

Brijesh
