Hi Daniel,

I just tested it and worked without problems. It might be due to an old J-link firmware. Please download the latest J-link software from Segger’s website and try again. You should not have any problems at all.

Hello Daniel,

Please verify the Jlink is connected with the red cable towards the pin 1 and 2 (see picture below). Also, if Jlink is properly connected and still not working, I would recommend you to use IAR IDE to flash the USB-KW24D512 board and make sure it is not locked or something similar.

If IAR IDE works, then I would recommend you to uninstall and install TestTool/BeeKit from scratch making sure you install it with administrator privileges (right click-> run as administration). If the device happens to be secured/locked, please use Jlink commander utility to unlock it as described in community post: https://community.freescale.com/thread/335458.

Hello Daniel,

If JLink connections have been verified to be ok, and board is listed as a COM port indeed, then it should be detected by the Jlink. Have you tried in another computer? Normally you could flash the board using IAR too, but if Jlink commander is not finding the board, the IAR will not either.

Please create a service request through our website so we could help you further and troubleshoot any problem your board may have. We will contact you shortly.

As mentioned, this seems to be an isolated issue with your current board setting. The service request will allow us to contact you and troubleshoot the problem directly.
