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
