We have a jeston agx orin platform, the software version is jack5.1, we customized a switching board, and accessed the camera through FPD-Link-III (DS90UB954/DS90UB953). We want to complete the integration of fpd-link based on the driver of imx185 in SDK. How do I need to configure it in the device tree?
hello 1508723374,
please refer to developer guide, Jetson Virtual Channel with GMSL Camera Framework.
you may see-also reference camera driver which using SerDes chip.
for instance,
$public_sources/kernel_src/hardware/nvidia/platform/t23x/common/kernel-dts/t234-common-modules/tegra234-camera-imx390-a00.dtsi
I have seen many posts on the forum that ds90ub954/ds90ub953 needs a driver, is it necessary to port this driver to the orin platform?
InES-HPMM/FPD-LinkIII_ds90ub95x: FDP Link III driver for ds90ub954/ds90ub953 (github.com)
hello 1508723374,
yes, please port the driver, it’s not supported by default.
you may see-also Jetson Linux 36.3 | NVIDIA Developer for [Driver Package (BSP) Sources].
I couldn’t catch the video stream through v4l2, and the cmos register configuration was all right. My suspicion may be that csi is not properly connected, please help me to see where the problem is. The following is the configuration of my device tree and the design schematic diagram of the custom adapter board.
tegra234-camera-imx185-a00.zip (3.9 KB)
hello 1508723374,
is it possible to probe the MIPI signaling via oscilloscope to confirm there’re packets on the CSI channel?
No mipi signal was measured. I don’t know why. There is another point I did not think about, there are four seats on the board, but I actually only used one, but generated video0~3, and then I set any device node can be enough to execute.ko files, and can read the register data, is it the characteristics of I2C_Mux? I don’t even know if the cmos register configuration Settings are in effect.
hello 1508723374,
there’s nothing software can be done without MIPI signaling on the CSI channel.
please review your hardware schematic and also power supply to ensure you’ve output the frame packets correctly.
Ok, let’s not worry about the mipi signal, let’s assume that the cmos register is not configured so that no data comes out. Then, as I mentioned above, the device tree is configured with four nodes, generating video0~3, but I directly a cmos, why can each device stage access this cmos, should not be able to access only one of them?
hello 1508723374,
I didn’t get you, are you talking from hardware point-of-view?
I am speaking from the software level, I use v4l2 to grab four data streams will execute drivers to configure registers, can read and write.
v4l2-ctl --set-fmt-video=width=3840,height=2160,pixelformat=BG10 --set-ctrl bypass_mode=0 --stream-skip=30 --stream-mmap --stream-count=1 --stream-to=ov1081.raw -d /dev/video0~3
hello 1508723374,
it was these two comments confused me.
it’s V4L2 IOCTL to verify basic camera functionality.
anyways, if you’re able to fetch the stream via v4l2, what’s the failure approach?
also, may I know which Jetpack release version you’re working with.
I can now grab the data stream, but it’s random.
Like that sometimes you catch it and sometimes you don’t.
hello 1508723374,
please review your pixel clock settings with SerDes Pixel Clock section.
may I also confirm the data-rate, is it larger than 1.5Gbps which related to skew calibration?
yes,My deserializer output is 1.6Gbps,I am still confused about how to configure this parameter serdes_pix_clk_hz.
serdes_pix_clk_hz=1.6Gbps*4/10=640000000

hello 1508723374,
there’re fixes added to support deskew calibration for high data rate sensors (> 1.5 Gbps).
please moving to the latest Jetpack-5 release version (i.e. Jetpack-5.1.3) if that’s possible.
I solved this problem by making 1.6Gbps->800Mbps, v4l2-ctl was able to grab video streams normally, but gst-launch-1.0 had no way to grab data.

hello 1508723374,
it’s v4l2 to verify the camera stream,
regarding to below…
this may be something incorrect in the sensor specific settings.
you may examine the device tree settings, especially the Property-Value Pairs.
I’ve been looking for a lot of posts on forums with similar questions, mostly via tegra-camera-platform {… } and tegra_sinterface solve this problem.
The following is my device tree configuration, please help me to see if there is any special problem.

hello 1508723374,
it looks all of your camera nodes using incorrect tegra_sinterface settings,
for example,
it should be serial_a for your camera node imx185_a.
since you’re developing your camera drivers based-on IMX185,
in order to avoid loading IMX185’s ISP override file, please update badge property to another unique string.
