Orin Nano support - Githubissues

masip85 commented 3 months ago

Hello

I've read Orin Nano is not supported. I've tried to use this project with 5.3 and 6.0 versions without success. Why is that? Can I modify something to achieve it?

Nir-Az commented 3 months ago

Jetson Nano is not "Officially" supported because it is not tested on our side. As I see, many users from the community use it. I recommend going over https://github.com/IntelRealSense/librealsense/issues

masip85 commented 3 months ago

But what I am seeing at the issues of librealsense is people who is using GSML with embedded (normally Connect Tech solutions). But I am using 9296 deserializer board.

I've found that at step:

With Jetson-IO tool: sudo /opt/nvidia/jetson-io/jetson-io.py

    Configure Jetson AGX CSI Connector
    Configure for compatible hardware
    Jetson RealSense Camera D457

With command line

sudo /opt/nvidia/jetson-io/config-by-hardware.py -n 2="Jetson RealSense Camera D457"

the output is: NameError: No configuration found for Jetson RealSense Camera D457 on Jetson 24pin CSI Connector!

What should I modify to test it?

masip85 commented 1 month ago

Ok. I've tried modifying this:

build_all.sh

-    cp $SRCS/nvidia-oot/device-tree/platform/generic-dts/dtbs/tegra234-p3737-0000+p3701-0000-nv.dtb $TEGRA_KERNEL_OUT/rootfs/boot/dtb/
+    cp $SRCS/nvidia-oot/device-tree/platform/generic-dts/dtbs/tegra234-p3768-0000+p3767-0005-nv.dtb $TEGRA_KERNEL_OUT/rootfs/boot/dtb/

Also I've avoided the headers with the pin configuration of the Orin, and I've changed them for the headers I believe are usable for :

I've been able to compile everything, install (copy). Even shows up in jetson-io.py and let me change it to the new configuration. BUT, after reboot, which boot properly by the way, nothing else happens. dmseg output shows nothing when I grep by d4xx. grep by tegra-capture-vi only showing three lines.

I've double checked dtb and Image has been properly copied.

I am using a Leopard Max9296 deserializer (https://github.com/IntelRealSense/librealsense/issues/11010#issuecomment-1429319228)

What could I try? It looks like is not very far from the goal.

@masip85, could you please check if I2C mux is detected or not? https://github.com/IntelRealSense/realsense_mipi_platform_driver/blob/dev/README_JP6.md#known-issues

masip85 commented 1 month ago

The Orin Nano I mentioned in previous post (I've been able to compile everything, install (copy). Even shows up in jetson-io.py and let me change it to the new configuration.) it's like nothing happened:

And yes, it's connected to csi slot 0 of orin nano dev kit.

Just in case, I paste you other Orin Nano (I've got it with JP5) normal message when you grep i2c is:

@masip85, looks like some i2c misconfiguration in device tree only. Could you please go over the forums and see if any of the conversations helps debugging the issue? https://forums.developer.nvidia.com/t/mipi-csi2-cam-i2cmux-i2c-2-duplicates-my-i2c-0-entry/182583 https://forums.developer.nvidia.com/t/imx219-board-setup-error-during-i2c-read-probe-121/160230

masip85 commented 1 month ago

First of all: I guess error during i2c read probe is not an issue. Imx219 sensor is not related to realsense driver. Moreover, this error appears too with default JP&kernel. Am I right? So what's the point of second link:

Just in case, I've made a check and: many relate "error during i2c read probe" to hardware connection problems too (not only, obviously). So, I've moved from one physical csi port to another. Changing ribbon csi cable too. The only thing I see changing is that now I see something connected from bus 10 to bus 9:

vmasip@nano:~$ sudo i2cdetect -r -y 9
     0  1  2  3  4  5  6  7  8  9  a  b  c  d  e  f
00:                         -- -- -- -- -- -- -- -- 
10: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- 
20: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- 
30: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- 
40: -- -- -- -- -- -- -- -- 48 -- -- -- -- -- -- -- 
50: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- 
60: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- 
70: -- -- -- -- -- -- -- --

By the way, no "UU" here in both buses. All logs are shown equal as before.

Regards the first link, I don't know what's the point you are looking for. Do you talk about this: https://forums.developer.nvidia.com/t/mipi-csi2-cam-i2cmux-i2c-2-duplicates-my-i2c-0-entry/182583/4?u=masip85 and changing this line?

Arun-Prasad-V commented 1 month ago

@masip85, I understand these forums are not directly related to this issue. They talk about few debugging steps. I meant to look at those and check if they can help narrowing down the issue.

I guess error during i2c read probe is not an issue. Imx219 sensor is not related to realsense driver. 
Moreover, this error appears too with default JP&kernel. Am I right?

-- Not sure. We have never tried with Orin Nano.

-- Yes, if that's applicable & possible based on your device tree.

What do you observe from below commands? sudo i2cdetect -l v4l2-ctl --list-devices

v4l2-ctl --list-devices

Cannot open device /dev/video0, exiting.

By the way, maybe the driver is not loaded? You've got more lines when you execute this.

vmasip@nano11:~$ sudo dmesg | grep tegra-capture-vi

I am checking the device tree and it's dependencies, and I really don't know if that line must be changed. I've got a lack of understanding of device trees.

I've been trying to obtain help from nvidia, but didn't work out. Do you have any clue I can try?
