Of course, SBC Axel is not composed of the combination of a SOM and a carrier board. Nevertheless, '''starting from XELK 2.1.2.0''', two ConfigIDs are used to identify the actual board configuration like it was a SOM+carrier board system.
For the sake of simplicity, the first ConfigID is denoted as ''SOM ConfigID'', while the second one is denoted as ''CB ConfigID'':
*''SOM ConfigID'' is used to identify the configuration of the basic features of the board
*''CB ConfigID'' is used to identify the peripherals and the I/O interfaces.
