Introduction

This article describes how the ConfigID is implemented in the products supported by the Axel Embedded Linux Kit (XELK).

AXEL

As AXEL is a system-on-module (SOM), the typical mechanism described here is used.

SBC Axel

Of course, SBC Axel is not composed of the combination of a SOM and a carrier board. Nevertheless, starting from XELK 2.1.0, 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#: 00000003
SOM UniqueID#: df646299:0b0579d4
CB ConfigID#: 00000012
CB UniqueID#: da000011:0dd2e72d
Board: MX6Q-AxelLite on SBCX
...

Generally speaking

  • 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.
