Freedom studio failing to run custom commands

Hello floks,

I am working with Hifive1 Board from freedom studio IDE. To run custom commands in IDE i have uncheck the Load symbol & Load executable in Startup tab and given “load <file.exe>” in Debugger tab there i was hitting an Error of MI commands failed to execute as shown below.

Can any one suggest me to Run Custom commads in freedom studio IDE.
