hi，Nino and Randy I am also trying to use J-Link in a command prompt that is controlled by automatic SW. I am using the CommanderScript method, and am able to control the J-Link, but am unable to get any useful returned data. do you have ways to print the log in the GUI tool (SEGGER J-Flash V6.12a) to command prompt window when error happens ? I can not find in the manual guide. you may understand what I'm saying from my attachment.
