MAC Address in eFuses BLK3

[thomas.schalch]

Hi everyone,

We want to use the ESP32 for mass production and store the MAC address in BLK3 of the eFuses. I've already read these instructions: http://esp-idf.readthedocs.io/en/latest ... ht=mac#id1
But I did not found an example for that. Has anyone already done this? How is the exact format of the key to be stored in BLK3? How exactly the CRC is calculated?

Thanks for your help!
