Real Time Object Detection Utilizing Nvidia Hardware

[jb7095]

Hello,

I’m currently working on a drone project involving real-time object detection and am using a Jetson Nano 2GB Developer Kit as the onboard processing unit. However, I’ve run into a major roadblock: I’ve forgotten the Ubuntu 20.04 password for the device, which has effectively locked me out.

Here’s what I’ve attempted so far:

1. I tried the standard GRUB recovery key combinations (Shift, Shift+Esc) during reboot. Unfortunately, they just return me to the login screen — no GRUB menu appears.

2. I attempted to reflash the microSD card using Balena Etcher. I used the sd-blob.img file referenced in NVIDIA’s setup guide (link), but that file appears to be a component, not a full bootable image. The issue persists.

3. I reached out to local electronics repair shops (Best Buy, Micro Center, etc.), but they don’t service Linux-based hardware.

At this point, I’m open to any recommendations — either to fully reset the Jetson Nano or move to a different platform. If password recovery isn’t feasible, I’m considering alternative hardware like another NVIDIA board or a Raspberry Pi 4/5.

If you’ve had hands-on experience running AI workloads (e.g., real-time inference with YOLO or TensorRT) on local edge devices, I’d appreciate any insights on what platform you’d recommend for any application.

Thank you for your time.

Hi,

Have you tried to reflash the device?
So you can set up a new password again.

Thanks.
