I recently tried updating jetpack from 4.5 to 4.6 but when I put in the SD card and boot up Jetson nano. It simply blinks the green light once and that’s it. Nothing comes on again, I’m confused at what happened since I’m currently using the barrel jack.
I need urgent assistance please
we have Nano flashed with JetPack-4.6 and it works normally.
could you please setup serial console and gather the complete bootloader messages for reference,
Here is what I get

What might be the issue
if by chance this is the issue …2x Jetson Nanos turn on with Green Light but no HDMI output - with Log Files
Can I use ubuntu 20.4 to run the sdk manager and if not how I can I dual boot 20.04 and 18.04 on my laptop, a link will be helpful here. Thanks
is this SD card format before? please refer to Getting Started With Jetson Nano Developer Kit | NVIDIA Developer and use the tools to format the card.
I’ve resolved the issue. Thanks
Hi, i’m facing the same issue with new image of jetpack 4.6, How did you solve the problem?
Flash the jetson using the SDK manager, but make sure you use ubuntu 18
