Question.
The USB default device was recognized, but when I connected a mouse or keyboard to the USB port, it was not recognized, so I installed the IC (W25XCL) from the developer kit on a custom board.
I installed it on a custom board and some of the USB ports worked.
Where can I find data about the W25X20CL?
Hi keyma305,
Sorry that I am not clear about your issue.
W25X20CL is a NOR flash from Winbond.
Why it relate to your issue about USB?
Are you using the devkit or custom board for Orin Nano?
What’s your Jetpack version in use?
I’m using Jetpack version 5.0.
Since USB connection wasn’t working, I inserted the W25X20CL from the development kit into my custom board that I’m designing, and this enabled partial USB functionality.
Please share the cat /etc/nv_tegra_release on your board.
Do you mean that you don’t have the EEPROM on your custom board by default?
If so, please refer to Jetson Orin NX and Nano Series — NVIDIA Jetson Linux Developer Guide 1 documentation to modify the BCT device tree.
After purchasing the Jetson Orin Nano Development Kit, I inserted the SD card into the nano module, installed the program, and checked the peripherals (screen, USB port) for normal operation.
The differences between my custom board and the Orin Nano Development Kit are as follows.
- only Wi-Fi, ETHERNET, NVME peripheral circuits were removed.
- separated USB3.1 Type-A x2 into USB-C and USB3.1 Type-A x1 (using hub ports DSP1 ~ DSP2)
- The custom board is equipped with all the same parts as the development kit (except for item 1 above).
A working Orin Nano module is inserted into the custom board,
USB does not work (W25X02CL part is installed).
To use item 2 above, IC U28 (W25X02CL) in the development kit must be removed and installed on the custom board to make the USB port work.
Only ports made with USB-C work, ports made with USB3.1 TYPE-A do not work. (Power is supplied.)
Please share your custom design in USB different from the devkit.
It seems it should be reviewed from our hardware team.

Repost the modified schematic.
Maybe you should check with your vendor first. They may refer to our design guide and reference carrier schematic.
