Hi, my issue is similar to his, but I have a separate power supply chip for the SD card. It can be confirmed that there is no problem with the circuit, but I can’t find the relevant files that need to be modified. Without changing any files, the device cannot detect the SD card. Continuing the disc…

Hi, I downloaded the L4T kernel archive, but I can’t find the following directories and configuration files. 1.hardware/nvidia/platform/t23x//bct/ 2.Controller Product Configuration’s configuration file. [屏幕截图 2025-11-11 222950] [屏幕截图 2025-11-11 223149]

Is this issue for Orin or Xavier? You are posting this question in Xavier NX forum in case you don’t know where you are now…

Hi, this issue is about Xavier NX. I know that t23x in the file directory should be replaced with t19x, but I still can’t find the corresponding directory and configuration files. Moreover, I also discovered a problem during this process: the Xavier NX module cannot use the graphical interface with …

I think the problem here is you totally don’t know what you are doing now. Let me check first. Do you have some background knowledge about how a device tree works? For example, the syntax and the rule. This has nothing to do with NVIDIA driver. It is a pure knowledge from Linux kernel which I …

Hi, I don’t really understand how device trees work.

Do you have anyone who is working on Linux software on your side? Some background knowledge here. Linux and the Devicetree — The Linux Kernel documentation

I have been learning from the Jetson Linux Developer Guide.
