The Toradex config block stored production data on the on-module
|
flash device (NAND, NOR or eMMC). The area is normally preserved by
|
software and contains the serial number (out of which the MAC
|
address is generated) and the exact module type.

For each serial number two Ethernet addresses are available for dual

Ethernet carrier boards. This options enables the code to set the
|
second Ethernet address as environment variable (eth1addr).
