2.5 MAC and Unique Key
MAC address :
Each ms14 has been assigned four world-wide unique, continuously MAC address in factory. They
are assigned to
wifi: MAC
eth0: MAC + 2
eth1: MAC +3
The [ MAC+1 ] is reserved for some applications which need two mac in wifi radio.
Unique Key :
A 32 bytes random number generated by TRNG is stored in art partition. Address range is 0x100~
0x11F.
A 2016 bytes random number generated by CSPRNG is stored in art partition, Address range is
0x0120 ~ 0x090F.
Those keys can be used for serial control purpose. To ready them, below is an example command
(assume mtd5 is art partition):
#read 16 bytes key from 0x100
hexdump -v -e '1/1 "%.2x"' -s $((0x100)) -n 16 /dev/mtd5
