As AXEL is a system-on-module (SOM), the typical mechanism described here is used.
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 ...
- 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.
|NXP (former FSL) guarantees that processors UIDs (a.k.a. SOM UniqueID# on XELK BSP) to be unique over the whole iMX6 family, olders i.MX and future i.MX products. This system was developed by FSL in early 2000 years.|
