Hi, I have a Jetson Nano 4gb developer kit rev B01 which is stuck on when powering on. The power led is on but nothing is displayed on my monitor. It seems that there is no power to the keyboard and mouse as well. This is the message I received when I connect it to a serial console when turning on the Jetson Nano:

I tried to flash the device with Jetpack 4.5.1 using the SDK Manager as well. but it remains stuck at 99.0% when flashing the device.

Is there any other method that can help resolve this issue?

2

Has this device been successfully flashed before?
Adequate power supply? Maybe remove all USB devices before flashing?
Try different USB cable to host?
When you flashed using flash.sh, did you use jetson-nano-qspi-sd as the board id?

Some users also have such error reported before. The only solution to fix this issue is through the sdkmanager.

As for your sdkmanager stuck issue, please check this page and see if this is really due to flash, or just sdk installation failure.

Yes this device has been successfully flashed before. Initially it was flashed using balenaEtcher. Everything was ok for a while. The device was powered off for around a week before using it again and it was at this time where I encountered this issue.

Alright, I will try to flash the device without any USB device connected to it.

Regarding using flash.sh, that is correct. I used jetson-nano-qspi-sd as the board id.

Alright. Noted on this. I will check out the link to find out more.

An update on the situation, I managed to flash the device successfully using the flash.sh method. After going through the general debug link provided by @WayneWWW, I saw that ssh was required and it was disabled on my linux host. After enabling ssh, the flashing procedure went smoothly and after that I am able to access the device again. Thank you for the help! I really appreciate it.
