Microchip Studio

In order to use J-Link with Microchip Studio, usually it is not necessary to separately install the J-Link software and documentation package. Anyhow, we recommend to make sure that the latest version of the J-Link software is installed and the DLL in Microchip Studio is updated to the latest version. Microchip Studio comes with a lot sample projects for various eval boards.

Using an Microchip Studio project with J-Link

The following steps explain how to configure a project to be used with J-Link.

• Open the project to configure
• Click Project | Properties from the main menu
• Click the Tool tab and select J-Link
• Make sure that the appropriate target interface (JTAG / SWD / ...) is selected
• Make sure that a proper target interface speed is selected (4 MHz works for almost all Cortex-M based targets and leads to good performance)

• Click Build | Build Solution from the main menu
• In order to start a debug session, click Start Debugging and Break.

• Now the project is ready to be debugged with J-Link / J-Trace.

Deactivating Compiler optimization

Microchip studio contains a compiler optimization for an optimized debugging experience.

You might need to deactivate that when debugging with J-Link / J-Trace.

• Click Project | Properties from the main menu
• Click the Toolchain tab and select <...> Compiler | Optimization
• Set Optimization Level to None (-O0)
