When a semihosting request is encountered, ISSM traps the request directly and the instruction in the SVC entry in the vector table is not executed. See your debugger documentation for more information about semihosting with ISSM.
To turn the support for semihosting off in ISSM, configure the target in your debugger or change the appropriate entry in the default.smc file:
