This article describes how the [[ConfigID and UniqueID|ConfigID]] is implemented in the products supported by the [[DESK-XZ7-L]] Linux Kit.
===ORCAHardware implementation ===BORA family uses the first 32bytes OTP block on NOR SPI to store ConfigID (and its CRC32), UniqueID (and its CRC32). For [[BORA Lite SOM | BORA Lite]] module configured for booting from NAND, the ConfigID is stored on internal I2C EPROM: see [[ConfigID_and_UniqueID#DAVE_Embedded_Systems.27_hardware_implementation | here]] for more information.
As ORCA is a systemU-on-module (SOM), the typical mechanism described [[ConfigID_and_UniqueID#ConfigID|here]] is used. Moreover, a '''system''' is composed of Boot integrates the combination of a SOM software routines for reading and a carrier board. In this case, two ConfigIDs are used to identify displaying the actual board configuration like it was a SOM+carrier board systemConfigID. For the sake Hereunder an example of simplicity, the first ConfigID is denoted as ''SOM ConfigID'', while the second one is denoted as ''CB ConfigID'': ''TBDat startup: riportare il dump del ConfigID e dell'eventuale cb_config_id dal dump di u-boot''

 === Generally speaking:===
*''SOM ConfigID'' is used to identify the configuration of the basic features of the SOM
*''CB ConfigID'' is used to identify the peripherals and the I/O interfaces.
