Question about Serdes_pix_clk_hz configuration

Robotics & Edge Computing Jetson Systems Jetson Thor
1

The current hardware is Jetson Thor,
The software version is JetPack 7.0 and Jetson Linux 38.2.

Currently, we are using Thor and gmsl to connect 8 cameras. The resolution of each camera is 1920x1536@30.
The current output rate of the MIPI lane of dser is 1.5 Gbps.
When I set the resolution to 1920*1080@30,
The rate is 1920 x1080x30x16x1.2x1.14 = 1,361,608,704.
1.5 Gbps this rate is sufficient for the transmission, so it is normal to output 4 images simultaneously.

According to the official documentation, the serdes_pix_clk_hz is configured at
375000000（1.5 Gbps * 4 lanes / 16 bits）However, this configuration cannot support the simultaneous output of 4 images. It will result in abnormal image display.

The required output rate is 1920x1536x30x16x1.2x1.14 = 1,936,510,156

Therefore, we need to configure the output of dser to 2Gbps. Currently, according to the official documentation of Nvidia, the maximum rate of dphy can reach 2.5Gbps. However, after I configured both sides to 2Gbps, v4l2 currently cannot receive any data. Below is the vi debug log. Please help me figure out what might be the cause.

hello heyang66,

the error code 0x110 means data-lane FIFO overflow.
please see-also similar topics for digging into data-lane FIFO overflow failures. such as… Topic 209574, and Topic 242054.

thank you for response
Hi, I’m synchronizing the logs for the 1.5Gbps configuration here,
There is no error related to PHY_INTR0 here.

Hello, I would like to inquire whether there are any instructions on increasing the VI/NVCIS frequency on the Thor platform?

Because I suspect that the clock of Thor might not be sufficient at present. Currently, it only supports data processing up to 1.5 Gbps. I have increased the input rate to 2 Gbps. Could it be that the CSI/VI module is unable to handle it?

hello heyang66,

please refer to developer guide, Supported Modes and Power Efficiency.
the default mode for Jetson T5000 is 120W, which already running at high frequency, you may try toggling to MaxM for another testing.

if that’s possible, please moving to the latest JP-7 public release version, Jetson Linux r38.4 for verification.

I referred to the responses on this forum and after configuration, I found that no images could be generated either. Could you please offer some suggestions? Currently, the output rate of our DESR is set to 2 Gbps. Should my SERDES_PIX_CLK_HZ be configured at this value?

23172b8c-f915-41ce-9a70-a85e2f0c8f78
23172b8c-f915-41ce-9a70-a85e2f0c8f781290×907 80.6 KB

The output rate of one lane is 1.5 Gbps. Under the condition of meeting the bandwidth requirements,
setting serdes_pix_ckl_hz to 3750000000 enables normal image display.
Therefore, I also have doubts about the configuration of this 125000000 value.
Why can this smaller value be configured?

it seems like an old discussion thread, may I know the topic-id from your snapshot?

I have noticed this Node.
Currently, we are using Dphy with a speed of 2 Gbps.
Would you like to know how the deskew signals are sent?

Skew calibration is required if sensor or deserializer is using DPHY, and the output data rate is > 1.5Gbps.

An initiation deskew signal should be sent by sensor or deserializer to perform the skew calibration. If the deskew signals is not sent, the receiver will stall, and the capture will time out.

You can calculate the output data rate with the following equation:

Output data rate = (sensor or deserializer pixel clock in hertz) * (bits per pixel) / (number of CSI lanes)

hello heyang66,

oh.. you’ve brought-up the camera stream, right?

12 
This is when the dser device outputs 1.5 Gbps. If serdes_pix_clk_hz is set to 3750000000, it can simultaneously output 3 normal signals. 
However, simultaneously outputting 4 signals is not normal. The abnormal state is shown in the following figure. Currently, after verification, it is suspected that the bandwidth is insufficient. 
I adjusted the output rate of dser to 2.5 Gbps/lane and serdes_pix_clk_hz to 6250000000. Now, not even one bit of data can be received normally.

I assume you’ve VC support enabled? see-also.. Jetson Virtual Channel with GMSL Camera Framework.
please share your device tree for cross-check, you may upload it as an attachment.

hello heyang66,

may I know your flash commands, it’ll not enable CSI if you used board configure file, jetson-agx-thor-devkit.conf, as you can see.. jetson-agx-thor-devkit.conf -> p3834-0008-p4071-0000-nvme.conf
you must perform image flashing onto p3971 to enable CSI bricks.
for instance,
SKU5: $ sudo ./tools/kernel_flash/l4t_initrd_flash.sh p3834-0005-p3971-0000 external
SKU80 (NVMe): $ sudo ./tools/kernel_flash/l4t_initrd_flash.sh p3834-0008-p3971-0000-nvme internal

17

I did not perform the flashing operation in the flash method.

I will place the generated dtbo file in the /Boot/ directory of Thor.

Then, by executing the command “sudo /opt/nvidia/jetson-io/jetson-io.py”, the overlay operation is performed.

I can confirm that the functionality of my CSI is functioning properly. When I configure a 1.5Gbps speed and output three images simultaneously, I can observe the preview data.

hello heyang66,

please try moving forward to the latest JetPack 7.1/r38.4 public release version for verification.

19

ok，I will verify the upgraded version.
