Jetson Nano B01 does not boot and LED Green

Hi. I have a Jetson Nano B01. It always works.One day he couldn’t boot,but LED light green。The system is on the TF card, and it can be used by replacing it with another one. It is sure that it is not a problem with the TF card system.

The serial output is this:

Hi tankliuhao,

Are yoy using the devkit or custom board?

There are some similar issue as yours.
Please refer to the following thread to check if they could help
The nano does not turn on today
Jetson nano 4g b01 not boot PT: Partition RBL NOT found!
Upgraded to Jetpack 4.6 on 5 Jetson Nanos 2 GB, now 4 won't boot

It looks something in QSPI has been modified.
You might need to re-flash with SDKM on standalone Ubuntu 18.04 host PC.

I use the official Nvidia jetson nano.I have exchanged two B01 motherboards, is it related to this situation?
Resulting startup error?

Does this issue occur after you change the carrier board?

There are some data written in QSPI, it might need to match the module which you use.

I haven’t flashed the problem board yet.

I have two Nvidia jetson nano devkit.Both can be turned on.But one day one does not boot and LED Green.Another can work.So I replaced the mainboard of both B01 kits.Ha ha. Both can’t boot.

I think there may be a problem with one and it spreads to the other.

Could you exchange them to original board and use SDKM to re-flash both board?
It should recover to normal working state.

OH,Yeah. I fixed them all.
I’ll tell you how to do it.

  1. Install 18.04 ubuntu to the U disk and start it with the computer.(The 18.04 version is very important, 20.4 cannot be used and do not install)
  2. Download from (sdkmanager_1.9.1-10844_amd64.deb)and install Jetson SDK Manager.Use this command to install(sudo apt install ./sdkmanager_1.9.1-10844_amd64.deb )
  3. Find the FRC and GND interfaces on the motherboard and connect them with wires.Connect the motherboard to the computer with a USB cable.
  4. Open Sdkmanager on the computer and log in to the NVIDIA developer account.The first step interface, select all, pay attention to the motherboard model.In the second step interface, select all. Downloading programs takes a long time.
  5. After the download is complete, click the install button, and the program will automatically install the system and refresh the QSPI information for the motherboard. Note that a TF card should be installed on the motherboard when installing the program, and I use a 128GB capacity.(Pay attention to unplug the connecting wire of FRC and GND when installing the software)It takes a long time to install the software, but you can’t leave it. You need to click some confirmation buttons and create a system account when installing.
  6. After the installation is complete, click the software exit button, and now the motherboard is updated. You can connect the monitor, connect the motherboard power supply, boot the motherboard again, and everything is back.
  7. Haha,good luck.
