Infineon ModusToolbox

In order to use J-Link with ModusToolbox, make sure that the latest version of the J-Link software and documentation package is installed. ModusToolbox uses Eclipse/CDT-based debug configurations, so J-Link can be selected as the debug probe in the project’s launch configuration.

ModusToolbox provides example projects for various Infineon/Cypress evaluation kits and devices. These examples can be imported and configured to debug via J-Link / J-Trace.

ModusToolbox also provides various tools for flashing, configuring, provisioning and developing applications for Infineon devices.

Using a ModusToolbox project with J-Link

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

• Open Eclipse for ModusToolbox
• Import or create the project to configure
• Build the project once to make sure that the application ELF file is generated
• Click the Run dropdown in the toolbar and select Debug Configurations...

• In the left-hand tree, select the debug configuration for the project

 ** Depending on the ModusToolbox version and installed debug support, this may be listed below GDB SEGGER J-Link Debugging or another GDB debug configuration type

• Make sure that the correct project and application ELF file are selected
• Make sure that the appropriate target device name is selected
• Make sure that the appropriate target interface is selected, for example SWD or JTAG
• Make sure that a proper target interface speed is selected

 ** 4000 kHz works for almost all Cortex-M based targets and leads to good performance

• Make sure that the paths to the J-Link GDB Server and the GDB client are correct

• Click Apply
• Click Debug to start the debug session

• ModusToolbox now downloads the application to the target and starts the debug session
• The project is now ready to be debugged with J-Link / J-Trace

Creating a J-Link debug configuration manually

If no suitable J-Link debug configuration exists yet, create one manually.

• Click Run | Debug Configurations... from the main menu
• Select GDB SEGGER J-Link Debugging
• Click New launch configuration
• Select the project to debug
• Select the generated application ELF file
• Configure the target device, target interface and interface speed
• Make sure that the paths to the J-Link GDB Server and the GDB client are correct
• Click Apply
• Click Debug

Notes

• Make sure that the device selected in the debug configuration matches the actual target device.
• When using SWD, make sure that the target board exposes the SWDIO, SWCLK, GND and VTref signals to the J-Link.
• If the target does not connect reliably, reduce the target interface speed.
• If the debug session does not start, verify that the latest J-Link software package is installed and that J-Link can connect to the target using J-Link Commander.
