We are using an AGX orin for our Autonomous car project and we have a PCA9685 connected to jetson via GND, 5V, SCL and SDA via I2C ports on jetson, we use this mainly for steering servo.

But we tried to power the PCA board via V+ rather then VCC and and we had a short circuit situation the GND and Power jumpers on both boards were melted and now we are not able to start our jetson completely as we did before

Now the jetson is just Flashing the LED for 1-2 secs but not powering up

We had our electronic Speed controller connected to the servo and the servo was further connected to PCA board so is there any possibility of reverse current flow from the ESC to jetson

Hi,
Here are some suggestions for the common issues:

1. Performance

Please run the below command before benchmarking deep learning use case:

$ sudo nvpmodel -m 0
$ sudo jetson_clocks

2. Installation

Installation guide of deep learning frameworks on Jetson:

3. Tutorial

Startup deep learning tutorial:

4. Report issue

If these suggestions don’t help and you want to report an issue to us, please attach the model, command/step, and the customized app (if any) with us to reproduce locally.

Thanks!

We are not able to run ubuntu as the Jetson is not powering on so unfortunately we won’t be able to run any code

Is there any safety mode that it goes to after sensing some problems because i am getting a long flash from LED for 2 sec and then no response

Are there any button combinations we could use to restart it

Hi koushalpokale1179,

What’s the Jetpack version in use?

Do you mean the AGX Orin can not boot up after your connect them(may be caused from short circuit)?

Is there any serial console log output?
Have you tried entering into force recovery state and check if it can be recognized by host through lsusb?

What’s the Jetpack version in use?
5.1.3

Do you mean the AGX Orin can not boot up after your connect them(may be caused from short circuit)?
Yes

Have you tried entering into force recovery state and check if it can be recognized by host through lsusb?
I followed these steps for Force Recovery 'Press and hold the Recovery button on the AGX Orin.
While holding the Recovery button, press the Power button to turn the board on.
After a few seconds, you can release the Recovery button.

but i am getting ‘no signal’ within the monitor so i dont know how i can use ‘lsusb’

lsusb
Bus 001 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub
Bus 001 Device 002: ID 80ee:0021 VirtualBox USB Tablet
Bus 002 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub

I tried to Reflash the device via SDK manager but it show ‘could not detect a board’ under target hardware.

Should i try getting outputs via UART-USB cable or it will give me same results?

You should connect USB-C cable between the devkit and the host.
lsusb should be run from your host to check if the devkit is recognized.

Please connect USB cable and run lsusb from your host to confirm if it can be recognized.

This was the output, i don’t see anything from Nvidia

It seems the AGX Orin is not recognized from your host.

Which USB-C port are you connected? Is it the one under power port or the one at another side?

Is there any serial console log output?
Please refer to NVIDIA Jetson Orin AGX - In Board - Getting in Board - Serial Console to setup serial console.
