We attempted to connect a 4GB Jetson Nano to a 2GB carrier board which should work according to this post . The 4GB Jetson Nano is using the latest version of the firmware “jetson-nano-jp45-sd-card-image.zip” which I downloaded from .
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.
Any help or advice would be appreciated.
