Hi everyone,
I'm currently calibrating an OAK-D camera and I'm encountering some issues. The error I'm facing is as follows:
RuntimeError: No PROTECTED permissions to override protected EEPROM field
Could anyone help me with this?
Calibration RuntimeError ERROR

You are trying to overwrite protected fields in the calibration file, (board_name, config,..). Create calibration handler in a way that none of those are present.
Basically only flash the calibration with the intrinsics/extrinsics, not the whole calibration.
Similar to: https://docs.luxonis.com/projects/api/en/latest/samples/calibration/calibration_flash/ which doesn't alter any of the protected fields.
Thanks,

Similar to: https://docs.luxonis.com/projects/api/en/latest/samples/calibration/calibration_flash/ which doesn't alter any of the protected fields. why i use this method ,not success.Failed flashing calibration: No PROTEcTED permissions to override protected EEPRoM fields

Hi Bob,
Even with that method, if your calibration file includes protected fields like board_name or camera_config, it will still fail. Make sure you're only flashing intrinsics/extrinsics using CalibrationHandler, not a full calibration dump.
Hope that helps!
thank you, abned, Here is my JSON file and calibration_flash.py. I have removed some protected fields, but this error still occurs.
