I’ve used well Jetson Nano for several months. After I just setup the initial Ubuntu first boot setup and rebooted. And then the SD card works well in that Jetson Nano board which was used to for the first boot.
But the problem is that the SD card does not work at all on other Jetson Nano boards: If power is turned on, the green LED is lit continuously but any screen is not displayed. Monitor does not get any video signal. But that board works well if I use the SD card image which is provided by Nvidia site. And I cross-checked all the combinations of trials.
Is there some solution or some comment for this problem?
The image file used for the first boot is: jetson-nano-jp451-sd-card-image.zip
