Micrium's µC/Probe

µC/Probe is an application to view and access the symbols of programs running on embedded systems.It visualizes variables and their values in meters, graphs and numeric indicators and gives the options to change or toggle the value of any variable.


µc/Probe can interface with the embedded system using a J-Link without the need of a kernel on the embedded system. It supports many cores and comes with the corresponding target codes to interface with them. Since version 3.0 Probe can interface with Cortex cores via J-Link out of the box, without any target code.
