Dear Gecko Experts,


I just updated to Simplicity Studio v3 on OSX and upgraded the firmware on my EFM32ZG-STK3200. Now when I use CrossStudio to connect to the Segger J-Link target, I get the following error:


Connecting ‘SEGGER J-Link’ using ‘USB 0’
Can not connect to J-Link via USB.

Has the support for Segger J-Link on STK3200 been discontinued and another debug interface is being implemented? Or what is the reason that after the firmware upgrade I cannot connect to my board in CrossStudio?
