GDB 

server 

Preliminaries 

SigGdbServer is an implementation ofthe GDB Server for the Signum JTAGjet 
emulator. It is used to debug ARM processors with GDB based debuggers on 
Windows systems.  

 

License 

The SigGdbServer server is designed for the use with the Signum JTAGjet emulator. This 

server-emulator tandem requires a license. If your emulator does not have it, an external license 
file must be obtained from Signum Systems. Once received, the Jxxxxx-Gdb.lic file needs to be 
placed in the directory where SigGdbServer.exe resides. (The xxxxx part of the actual file name 

is the serial number of your JTAGjet emulator.) Alternately, the license file can be placed in the 
C:\Signum\Licenses folder where it becomes available to other applications, such as Chameleon 

Debugger or Flasher.
