ConfigID (XUELK)

Info Box Applies to AXEL ULite Applies to SBC Lynx

Introduction

This article describes how the ConfigID is implemented in the products supported by the AXEL ULite and SBC Lynx Embedded Linux Kit (XUELK).

AXEL ULite

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

SBC Lynx

Of course, SBC Lynx is not composed of the combination of a SOM and a carrier board. Nevertheless, starting from XUELK 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:

U-Boot 2016.03-xuelk-2.0.0 (Sep 13 2017 - 23:42:07 +0200), Build: jenkins-XUELK_U4

CPU:   Freescale i.MX6UL rev1.2 528 MHz (running at 396 MHz)
...
SOM ConfigID#: 00000013
SOM UniqueID#: e6b3f362:042961d4
...
CB ConfigID#: 0000002f
CB UniqueID#: 00000000:00000000
Board: MX6UL SBC Lynx
...

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.
