Segger J-Link Tools

In order to use this library, you will need to have installed the SEGGER tools. The tools can be installed from the SEGGER website here. This package is compatible with versions of the SEGGER tool >= 6.0b. Download the software under J-Link Software and Documentation Pack for your specific hardware. PyLink will automatically find the library if you have installed it this way, but for best results, you should use one of the two methods listed below depending on your operating system:

On Windows

Windows searches for DLLs in the following order:

1. The current directory of execution.
2. The Windows system directory.
3. The Windows directory.

You can copy the JLinkARM.dll to any of the directories listed above. Alternatively, add the SEGGER J-Link directory to your %PATH%.

On Linux

# Option A: Copy the library to your libraries directory.
cp libjlinkarm.so /usr/local/lib/

# Option B: Add SEGGER's J-Link library path to your libraries path.
export LD_LIBRARY_PATH=/path/to/SEGGER/JLink:$LD_LIBRARY_PATH

On Mac

# Option A: Copy the library to your libraries directory.
cp libjlinkarm.dylib /usr/local/lib/

# Option B: Add SEGGER's J-Link directory to your dynamic libraries path.
export DYLD_LIBRARY_PATH=/Applications/SEGGER/JLink:$DYLD_LIBRARY_PATH
