    Hi

    My name is Stephen and I work at Arm.

    The error message
    Error: L6915E: Library reports error: __use_no_semihosting was requested, but _sys_command_string was referenced.
    is saying you requested no semihosting functions may be linked-in from the C libraries, but _sys_command_string (which uses semihosting) was referenced.

    You will need to either add your own retargeted version of _sys_command_string into retarget.c, or remove the use of argv and argc to pass parameters to main().  See:

    developer.arm.com/.../-sys-command-string--

    Hope this helps
