ARM, RISC-V контроллеры

1-ый вариант меня страшит из-за информации в мануале: 

5.11.2.2 IAR Embedded Workbench The J-Link command strings can be supplied using the C-SPY debugger of the IAR Embedded Workbench. Open the Project options dialog box and select Debugger. On the Extra Options page, select Use command line options. Enter --jlink_exec_command "<CommandLineOption>" in the textfield, as shown in the screenshot below. If more than one command should be used separate the commands with semicolon.

Тогда как я эту "CommandLineOption" как раз и не умею заполнять. 2-ый вариант меня вполне устраивает. Подскажите (желательно подробнее), какие шаги здесь следует предпринять. До коннекта я успешно дохожу, но не понимаю, что делать дальше:
