Nano B01 not recognizing Pi camera v2.1

I have two Jetson Nanos (B01) that won’t recognize a Raspberry Pi Camera (v2.1)(both items were from SparkFun). I’ve tried two different v2.1 cameras in both slots on both Nano units.
I’m facing the cable blue side out, silver side towards the inside. I’ve confirmed visually that the silver contacts are aligning. I’ve tried powering the unit via the USB port and the barrel jack.
Any help at all troubleshooting will definitely be appreciated. One of the other threads suggested a hardware issue that was fixed via RMA.

The dmesg output shows:
i2c-mux-gpio cam_i2cmux: 2 port mux on Tegra I2C adapter adapter

Other info:
i2cdetect doesn’t see it.
The nano is patched to the latest version. Nothing has been installed other than the standard software updates.

Thanks, Rick

Are you able to probe the i2c signal to confirm it?

Unfortunately, I don’t have any hardware tools that allow me to take measurements.
Are there any other steps I can take?

Thanks, Rick

There’s no other way to check from software if it’s HW issue.

I bought a Pi 4 and played around with the cameras. At first neither worked, but after I reseated the ribbons on the camera side, one of them began to work. I took the working ribbon and tried on the other camera, but it didn’t work there. So, I took the working camera over to the Jetson and it worked there also. I thought I was going crazy there for a while.
