reComputer J401 Carrier Board fails to load VEYE camera /dev/video0 device with Jetpack 6.2

A new problem with the J401 carrier board and the “Compatibility Issue between reComputer and VEYE Camera”

After flashing Jetpack 6.2 to the J401 Carrier Board with an Orin NX module (reComputer J4011), I applied the USB hub chip firmware fix for the Veye camera (this updates the carrier board USB firmware from FW Version 07F3 to FW Version 08C3):

The Veye camera driver then loads and the camera I2C address is detected:

$ lsmod|grep veye
veyecam 16384 0
tegra_camera 253952 3 nvhost_isp5,veyecam,nvhost_vi5

sudo dmesg|grep veye

but no device /dev/video* is generated. (It is generated at Jetpack V6.1).

Has anyone else seen this error?

Has anyone successfully enabled the VEYE IMX462 Camera on the J401 carrier board with Jetpack 6.2?

Could there be a solution (updated) for compatibility between reComputer and VEYE Camera at Jetpack 6.2 (it is compatible at Jetpack V6.1).

Thanks

Flashing the NVIDIA Jetpack 6.2 build to an Orin Nano Developer Kit, the Veye camera driver then loads, the camera I2C address is detected, and the device /dev/video0 is generated.

Hence the problem generating the video device with Jetpack 6.2 on the J401 is an incompatibility between the J401 carrier board and the Jetson Orin Nano reference carrier board, or an issue with the Seeed Jetpack 6.2 mass flash image:

mfi_recomputer-orin-nx-8g-j401-6.2-36.4.3-2025-07-14.tar.gz

I loaded from Flash the device step by step.

Next I will try flashing the J401 with the basic NVIDIA image. Even if that were to work for our production units, it would not be a full solution since the NVIDIA build does not include PPP support. But does this help point to where the Veye camera incompatibility is?

Hi there,

So , You do know the are NOT exact clones. Yes the Device tree and some other items are indeed different than the original. i.e. not 100% plug and play. I would give them some time to test it, now that you brought it to their attention don’t pile on other issues’ or you get no-ware fast. (stick with the compatibility) Once it’s patched correctly it should all work like the others.
