This is a glossary of terms used in embedded Linux, and links to existing glossary pages:

Here are pages that have list of terms for specific technology areas:


A

Abatron 
Abatron is a Swiss company that makes a popular Jtag debugger often used to debug embedded Linux. Their primary products are the 'BDIx000' line of Jtag debuggers.

B

BSP 
Board Support Package. This is the code that is used to support a particular hardware board. The term is used generically to refer to code, and not a specific "package", as the name implies. It generally refers to all special-case software relevant to a particular board, whether it is kernel code, user code, etc.

E

Embedded 
An "Embedded" device usually means one with fixed functionality, independent of other additional hardware or software attributes. The terms is somewhat vague. This is as opposed to general-purpose functionality. Note that mobile phones are considered embedded, although they now support general-purpose programs and functionality. Classic embedded Linux products include things like digital cameras, routers, television sets, and settop boxes, as well as non-consumer embedded devices like sensors, industrial control devices, and pretty much anything running Linux outside of the desktop and server markets.
