The example programs bundled with Oki's ML674K CPU boards generally do not require ARM Semihosting to be enabled. In some cases, having Semihosting enabled will interfere with the performance of the sample software. As a rule, any sample program that uses the init.s module, does not require semihosting.

Although, the flash utility that is provided for ML674000 CPU board requires Semihosting to be enabled and it will not function properly without it.

To disable semihosting in ARM debuggers, select Debugger Internals and set the semihosting_enabled variable to 0x00.
