Introduction[edit | edit source]
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[edit | edit source]
As AXEL ULite is a system-on-module (SOM), the typical mechanism described here is used.
SBC Lynx[edit | edit source]
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 ...
- 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.
The complete list of supported SOM ConfigID/CB ConfigID combinations is detailed here.
