TCF is a lightweight, extensible network protocol for driving embedded systems (targets).

On top of the protocol, TCF provides a complete modern debugger for C/C++ and Ada, as well as the "Target Explorer" for system management. TCF works out of the box for Intel, PPC, ARM and RISC-V Linux targets. It supports Proxying and Tunneling for IoT devices, and is particularly strong for multi-process debugging even with slow communication links.

The TCF Framework makes it very easy to build your own tools using the components provided:

• The lightweight agent under EDL / BSD license is written in C, and very easy to port or embed in custom OS's or "bare metal"" hardware debuggers and simulators.
• DWARF reader and Symbol Services are written in C and can be used independent of the debugger.
• TCF Language Bindings for C, Java, Python and Lua allow driving your tools from scripts.

See the TCF Wiki for details.
