Hi everyone,

my jetson nano board is not booting. So I’ve connected UART pins to an arduino to see what’s going on. Below is the full dump of boot sequence, collected from serial console, until it stucks. Any idea how to solve this ?

Edit: I’m using freshly flashed SDCARD Using below image:

I’m facing the same issue with my Jetson nano and getting the same logs. The green light is on and there are no logs beyond this on the serial console.

I’m using Sandisk Extreme Pro microSD card (128GB) and raspberry pi power supply.

Hi,

Could you directly flash the whole board with sdkmanager instead of using sdcard image? I guess that should resolve your issue.

Hi @WayneWWW, to flash the whole board using sdkmanager, do I need to connect the board to my laptop using headless mode (https://developer.nvidia.com/embedded/learn/get-started-jetson-nano-devkit#setup-headless) or is there a way I can do this with microUSB power supply?
Thanks.

If you never use sdkmanager before, better reading the document here.

Headless mode has nothing to do with flashing. You have to use jumper to put device into recovery mode and then run the flash command.

Thanks for the info.
In Install Jetson Software with SDK Manager :: NVIDIA SDK Manager Documentation it says the device has to be connected to the host machine. How do I connect the jetson to my laptop?
Also, if you could link to any steps for using sdk manager with jetson nano that would be of great help.

Please download SDK Manager and follow these instructions

Thanks, this worked.
