When I tried to add a new Arduino Nano 33 IoT over the web interface of IoT Cloud I get an error saying writing to ECCX08 failed. I tried to upload the Proviosining.ino sketch from the examples section of Arduino IDE and I can confirm I get the same error:
Your ECCX08 is unlocked, would you like to lock it (y/N): y
Writing ECCX08 configuration failed!
Could someone help? As far as I can tell ECCX08 is supposed to be written on once. Does that mean my Arduino is faulty?
@recai, your topic has been moved to a section on the forum where it probably gets the exposure it deserves.
If you have anything connected to pins A4 and A5 on your board, try removing those connections. A4 and A5 are the I2C bus pins and are used for communication with the ECC508 crypto chip on the Nano 33 IoT.
Thanks. I do not have anything connected to board. I soldered the headers, but nothing else. I also checked there are no shorts between the legs and especially between A4 and A5.
