Here is the way to exit Qemu with a debug exit instruction

Run qemu with

-device isa-debug-exit,iobase=0xf4,iosize=0x04

qemu-system-x86_64 -nographic -serial mon:stdio -kernel build_qemu/zephyr/zephyr.elf -device isa-debug-exit,iobase=0xf4,iosize=0x04

Use this function to write to the exit iobase:

void dbg_io_write_8(uint16_t port, uint8_t val)
{
	__asm__ volatile("outb %0, %1" :: "a" (val), "Nd" (port));
}


dbg_io_write_8(0xF4, 0x4);

The problem is the Unity and Cmock system uses the native_posix build which is not compatible with my system.

west build -b native_posix -t run

Hi,

I am not sure if this is the right forum to ask but it seems like the qemu are run indefinitely until you exit them from the command prompt manually.

Unity and CMock are widely use to test zephyr based funtionality. Most likely you already knew about these?
