The SEGGER Cortex-M Trace Reference Board is a simple hardware with
   an ARM Cortex-M4F based microcontroller, that supports the Embedded
   Trace Macrocell (ETM). Its prime purpose is to quickly set up a
   reference project for instruction tracing and live code coverage and
   profiling.

SEGGER emPower Cortex-M4 Evaluation Board comes complete with evaluation versions of the following software components accelerating the start of any embedded project.

• embOS (Real Time Operating System)
• emFile (File System)
• emWin (Graphic Software & GUI)
• emUSB Device (USB Device Stack)
• emUSB Host (USB Host Stack)
• embOS/IP (TCP/IP Stack)

SEGGER embOS/IP Switch Board comes complete with an evaluation version of embOS/IP with the Tail Tagging feature. The Tail Tagging enhancement establishes a virtual Multiport when only one physical Ethernet port is available on the CPU.
