We attempted to connect a 4GB Jetson Nano to a 2GB carrier board which should work according to this post [1]. The 4GB Jetson Nano is using the latest version of the firmware “jetson-nano-jp45-sd-card-image.zip” which I downloaded from [2].
The problem we found that once the OS boots, none of the USB ports seem to work. This means we cannot use any USB devices such as a mouse or keyboard. Observationally the laser beneath the optical mouse does not turn on so it appears like there is no power going to the USB.
I can confirm that the 2GB carrier board itself is working properly because if we use a 2GB Nano on the same carrier board, everything works just fine.
Similarly the 4GB nano is also fine if tested with a 4GB carrier board.
The issue only arises if the 4GB nano is connected to the 2GB carrier board.
If you are using below combination:
Nano-4GB devkit + Nano-2GB module + JP-4.5 nano sd image.
Please use Nano-2GB JP-4.5 SD image and try usb function again.
Thanks!
It looks like the SD Image that I should use should match the carrier board instead of the Nano Module. This seems counter-intuitive to me. What image should I use if I used a third-party carrier board?
The image is what module you used.
The Nano-2GB module, please use Nano-2GB image.
The same, Nano-4GB module, please use Nano-4GB image.
If you used the third-party carrier board, please connect vender. Thanks!
It looks like similar to my case.
I tried Jetson Nano module(emmc) to 2gb dev kit’s carrier board. But after flashing os by SDK manager, I found USB does not work.
I tried 3 OSs(Nano module, Dev kit, 2Gb dev kit) and still can’t use USB.
