We designed an Orin NX carrier board according to the specification, but an error message “I2C_DEV error” was displayed during startup. May I ask how this situation is caused and how to solve it?

Hi vanceyqs,
What’s your Jetpack version in use?
It seems the error from MB2.
Do you have EEPROM on your custom carrier board?
Is there any design about I2C different from the devkit?
Thank you for your reply. The version of Jetpack is 35.3. I think I have found the problem. I2C2 does not design EEPROM circuit on my carrier board. I think this is the cause of the failure to boot normally.
Please refer to the following instruction if you are not using EEPROM.

OK，thank you!
