we have basically same commandline for two different controllers: psoc and MKV5x Commandline: $(flash_jlink_exe) -CommandFile $(flash_jlink_path_set) -Log $(flash_jlink_log) you can find commandfile and output in the attachments. The Problem is, that mkv5x is not flashed, instead it keeps hanging at the gui-server... even more problematic is, that no pop up or whatever shows up... same for jlink 7.64 and 7.90 But for 7.90 there is one difference, the command-sqeuence about gui-server is processe…
