Calling that function (before setting real linux mac address) returns MAC address 00:00:20:07:03:09. Changing NVS data at position 0x1c-0x21 changes also what above function returns. So really at position 0x1c-0x21 in NVS data is stored MAC address (in reverse order). Just default is some unknown 00:00:20:07:03:09. So MAC address is really part of NVS data. -- Pali Rohár pali.rohar@xxxxxxxxx
