Guideline for a Design of a Custom Baseboard for Kontron SOM

This design guide is intended to minimize the development risk of an own baseboard and also the software adaptation effort.

We therefore recommend that you copy the functions you need 1:1 from the reference schema. 


PREVIEW

For a reference schematic contact our sales group. 


The following guidelines must be observed for the support of our Standard SOM CODESYS Images.

Used features in standard images:

Default Bootloader: 

  • microSD Card Slot

  • Debug Port

  • USB

  • ENET1


Image Update over USB is only supported if a valid rescue system (bootloader, rescue partition) is installed on the internal flash.

Creating Custom Device Tree File

The device description can be created and tested directly in the webconfig.
For this you can simply install the package systemwebconfig-dtceditor via the package manager.
