Concepts
In this section you can find a more detailed explanation of the concepts used in the Jumpstarter project.
| Concept | Definition |
|---|---|
| Testing Harness | This is the physical device used to allow Jumpstarter interfacing into your hardware, one example of this is the dutlink-board which is an Open Hardware reference design for Jumpstarter. But other Testing Harnesses can exist. |
| DUT | Device Under Test: This is the device that you connect to your |
| Serial console | Embedded devices and most servers have one or multiple serial consoles. A serial console allows you to transmit and receive bytes via
a TX and RX line (plus Ground), sometimes in RS-232 physical voltage levels, sometimes in digital voltage levels (i.e. 3.3v, 1.8v, etc..),
most bootloaders, UEFI bios, and the kernel can communicate through a serial console. i.e. the kernel accepts the
console parameter
to let you direct the main kernel output and console, for example using the kernel parameter
console=ttyS0,115200. In jumpstarter
we use the console as a the main communication method to Edge devices, with the purpose of monitoring and automation |
