Minimum CSS Version Requirements

In order to use J-Link with TI CCS, min. V6.1.3 of TI CCS is required. Earlier versions might work but are not guaranteed to do so. Please understand that SEGGER does not provide any support for CCS versions earlier than V6.1.3.

Adding J-Link support at installation time

Since TI CCS v7, J-Link is supported out-of-the-box if J-Link support is selected to be added at installation time of CCS. For more information regarding older versions of CCS: Adding J-Link support to older CCS versions.

Connecting to a J-Link via Ethernet

Problem

In current versions of the TI Code Composer Studio (CCS), the host interface to the J-Link (USB / Ethernet) can not be specified in the project settings.

Work-around

The J-Link DLL allows to override the used host interface using the J-Link Commander String SetHostIF. This command string can be passed to the J-Link DLL using the J-Link Script File function InitEMU(). Please find below an example J-Link Script File, which forces the J-Link DLL to open a connection to the J-Link via IP (192.168.104.174). How to use J-Link script files in CCS is described in the article below.

File:JLinkOverrideHostIF.jlinkscript

Notes

  • The work-around can be used with any J-Link with Ethernet interface.
  • Native host interface selection, using the GUI in CCS, is planned for future versions.

Using J-Link Script Files

  • Make sure that J-Link CCS uses at least J-Link software version V6.20g
  • Open the project
  • Switch to the Project Explorer, browse to %PROJECT_NAME% --> targetConfigs and open the active target config with *.ccxml extension (e.g. CC2650F128.ccxml)

  • Select the Cpu properties (see screenshot below)
  • Switch to the Advanced tab (see screenshot below)
