3.3.2.2 GDB Server user interface
The J-Link GDB Server's user interface shows information about the debugging pro-
cess and the target and allows some in progress configurations.
It shows following information:
• IP address of host running debugger.
• Connection status of J-Link.
• Information about the target core.
• Measured target voltage.
• Bytes that have been downloaded
• Status of target.
• Log output of the GDB Server (optional, if Show log window is checked).
• Initial and current target interface speed.
• Target endianess.
These configurations can be made from inside GDB Server:
• Localhost only: If checked only connections from 127.0.0.1 are accepted.
• Stay on top
• Show log window
• Generate logfile: If checked, a log file with the GDB <-> GDB Server <-> J-Link
communication will be created.
• Verify download: If checked, the memory on the target will be verified after
download.
• Init regs on start: If checked, the register values of the target will be set to a
reasonable value before on start of GDB Server.
3.3.2.3 Running GDB from different programs
We assume that you already have a solid knowledge of the software
tools used for building your application (assembler, linker, C compiler) and
especially the debugger and the debugger frontend of your choice. We
do not answer questions about how to install and use the chosen toolchain.
GDB is included in many IDEs and most commonly used in connection with the GCC
compiler toolchain. This chapter shows how to configure some programs to use GDB
and connect to GDB Server. For more information about any program using GDB,
please refer to its user manual.
emIDE
emIDE is a full-featured, free and open source IDE for embedded development
including support for debugging with J-Link.
To connect to GDB Server with emIDE, the GDB Server configurations need to be set
in the project options at Project -> Properties... -> Debugger.
Select the target device you are using, the target connection, endianess and speed
and enter the additional GDB start commands.
The typically required GDB commands are:
J-Link / J-Trace (UM08001)
