Warranty Help needed for Jetson Nano

My I2C bus appears to have failed

ValueError: No I2C device at address: 3c

I’ve been working with the Jetbot project, and the display is the same called for in the bill of materials (SSD1306. Adafruit Part # 3527)
The device has been working fine up until yesterday, when it simply stopped giving a display. Also the motor controller, which is connected to the same pins as the display, also stopped working at the same time

I tested the SSD1306 as being functional by installing it in a Raspberry Pi3 and running the same stats.py program that was in the Jetbot, and the display works on the Pi

Hi, did you check the output log info? Is the system dead and can’t power on or just the I2C failed? If latter, is it possible to try another I2C of Jetson? If system is dead, maybe you need to run RMA for the board

Yes, I have the log info. It just repeats over and over, so I’ll just post one section…

It does still power on, but, even if it did still work on a different I2C, that would still mean that the thing isn’t functioning up to par, and I’d much rather RMA it. I only bought it on June 1 2019, so still well within the warranty period

Nvidia responded, and agreed that the unit should be RMA’d

They emailed me a prepaid label to send the thing back, and they promise that it will be handled in 5 days or less

Thank you Nvidia
