Not sure about JSON, but CUSTOMER_KEY_HASH is all zero (I haven't flashed it yet, and currently want to test everything before making irreversible changes)To verify whether the public key has been programmed you could enable the recovery_metadata option
Uncomment recovery_metadata=1 in config.txt
https://github.com/raspberrypi/usbboot/ ... g.txt#L10You should then get a JSON file showing OTP settings including the public key hashCode:
recovery -v -d . -j metadata
