Jetson Xavier NX Dev Kit Image Flashing w/o microSD Card

How do I go about flashing a new Jetpack 5.0.2 onto a Xavier NX Dev kit where it does NOT have a microSD card?

My version has a PCIe NVME M.2 SSD, but no where to insert a microSD card.

I’m locked out of the login, so need to flash in order to start from scratch & update to 5.0.2.

Thanks in advance.

Hi smcentee,

Your board might come up with eMMC (instead of microSD), and you can just flash into it.
Please use NVIDIA SDK Manager to flash your Dev kit
Install Jetson Software with SDK Manager :: NVIDIA SDK Manager Documentation

Thank you. That got me started but when I try and flash the dev kit, it is asking for the login and password on the kit. Since I don’t know this since I can’t login at all, how do I reset or create a new user on the kit? I tried the Ubuntu ‘hold down the shift key during boot’ but it doesn’t recognize it.


Flash is normally just to install the operating system. It is after flash completes and the system self-reboots that it asks for a name/pass for the purpose of installing other software, e.g., CUDA. The problem is that the first boot requires you to run the first boot account setup, otherwise there won’t be a login name or password. Does it give you an opportunity during boot to set this up if you run either from a local monitor/keyboard, or via serial console?

After much trial and error. I was able to flash (my dev kit only had a nvme drive, not a microSD). I was able to login after re-flashing…

Since I had never done it before, I found a good site that explains exactly how to do the install and flash. I am sharing it here for others:
