Hello everyone, I have installed JetPack 5.0.1 Preview on Jetson Xavier NX, and was not able to get the IMX477 cameras running. I saw in here that I need to modify the device tree. But I do not understand how I can do that without flashing it again since I am new to this? Is there a solution to fix…

hello king_kaleb , you’re able to disassembler the dtb file into text file for modification, $ dtc -I dtb -O dts -o temp.dts tegra194.dtb after that, please convert the DTS into a new DTB file, $ dtc -I dts -O dtb -o new-output.dtb temp.dts

Hi @JerryChang , Thank you for the quick response. However, I was not able to find the tegra194-p3509-0000-a00.dtsi file. The closest file I could find was /boot/tegra194-p3668-all-p3509-0000.dtb. Can you please tell me where I can find the dts file I need to edit? or can you perhaps provide me a li…

hello king_kaleb, you may check /boot/extlinux/extlinux.conf for FDT entry, it shows the device tree file you’re using. usually the binary file is located at /boot/, please modify the binary file for testing. thanks

HI @JerryChang , Thank you! The device tree file is /boot/dtb/kernel_tegra194-p3668-0000-p3509-0000.dtb. I have edited the file, converted it back to dtb and replaced it. However, it is still not working. I have uploaded the dts file here: kernel_tegra194-p3668-0000-p3509-0000.dts (297.4 KB) Thank…

Hi @JerryChang , Thank you! That was useful. I followed the instructions and also downloaded this file and replaced my dtb file. Now, running sudo /opt/nvidia/jetson-io/jetson-io.py does not work. It shows the gray screen and automatically closes. Thank you for the continuous support!!

[image] king_kaleb: It shows the gray screen and automatically closes. hello king_kaleb, please setup a terminal and gather the kernel logs for reference, thanks

Hi @JerryChang , Sorry, I was not able to follow. Can you please elaborate more on how I can do that? Sorry for my ignorance on this. Thank you!

[image] JerryChang: kernel logs I have viewed all the log files in /var/log/ but I couldn’t find anything relevant to jetson-io. Am I looking at a wrong location?

hello king_kaleb, please running command, $ dmesg to gather kernel logs, you may also apply options, $ dmesg --follow to view kernel messages immediately. Jetson-IO utility is under /opt/nvidia/jetson-io/, you may use the command $ sudo python jetson-io.py for running it.

Hi @JerryChang , Thank you! The only error I could see in the log that’s relevant is the following: [ 8.695570] rtl88x2ce 0004:01:00.0: enabling device (0000 -> 0003) [ 8.700229] imx219 9-0010: tegracam sensor driver:imx219_v2.0.6 [ 8.710928] imx219 9-0010: imx219_board_setup: error during…
