Recently, I try to build stm32l4 mac under the development environment with eclipse + gcc_arm+JLink (MacOS 10.12)

I convert stlink to JLink wite the soft de SEGGER with my board STM32L476 Evaluation.

I got the console message:

Restoring target state and closing J-Link connection...


I am not very experienced in this build environment. I'm not sure it's the problem of the configuration debug or linked file ?

Any help would be appreciated.
