ConfigID[edit | edit source]
This article describes how the ConfigID is implemented in the products supported by the DESK-MP1-L Linux Kit.
ETRA[edit | edit source]
As ETRA is a system-on-module (SOM), the typical mechanism described here is used.
Moreover, a system is composed of the combination of a SOM and a carrier board. In this case, 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#: 00000001 SOM UniqueID#: 39303435:33385105:001e0024 CB ConfigID#: 00000001 CB UniqueID#: 0d000035:c4a4762d Board: ETRA on SBC ...
Generally speaking:
- SOM ConfigID is used to identify the configuration of the basic features of the SOM, it is stored in the OTPs on the SOC.
- CB ConfigID is used to identify the peripherals and the I/O interfaces, it is stored in an external one-wire eeprom memory present in the carrier board.
