Why factory MAC address is not write protected in efuse?

Postby kokonuts » Thu Mar 02, 2023 6:12 am

By running this command: espefuse.py summary
I can see:
MAC (BLOCK1) Factory MAC Address = f4:12:fa:50:31:b0 (OK) R/W

If the efuse is "burnt" at the time of production, how come it shows R/W ? According to docs, it should be R/-
Or am I missing something ?
