3 years ago It looks like the repeating error message still allowed for a login command prompt and the system accepted user input. I was able to login and issue the following commands to stop the i2c error:
sudo systemctl stop jetbot_stats sudo systemctl disable jetbot_stats
sudo systemctl stop jetcard_display sudo systemctl disable jetcard_display
Still having an issue with X server, but I will close this issue for now.
I installed both jetcard and jetbot from scratch and ran into the following boot error (i2c complaining about cable not connected I think):
"tegra-i2c 7000c400.i2c: no acknowledge from address 0x3c error"
I believe the boot error is related to the display services.
Is there any way to work-around the error and get to a command line so the display services can be disabled?
Is a serial cable and console required at this point? A fallback option could be to rebuild the jetcard image from the jetpack image (again).
jetbot - create-sdcard-image-from-scratch.sh
jetcard - install.sh
install jetcard display service
python3 -m jetcard.create_display_service echo $password | sudo -S mv jetcard_display.service /etc/systemd/system/jetcard_display.service echo $password | sudo -S systemctl enable jetcard_display echo $password | sudo -S systemctl start jetcard_display
Install jetbot services
cd jetbot/utils python3 create_stats_service.py sudo mv jetbot_stats.service /etc/systemd/system/jetbot_stats.service sudo systemctl enable jetbot_stats sudo systemctl start jetbot_stats
