Hi Pedro, No, I don't think there's an easy way to run m5_write_file on the guest from the host. That is an instruction that is executed on the guest, and the host can't easily control what is executing on the guest (especially when you consider that it has to execute in the right context, etc.). Similarly, the host doesn't have any (easy) way of knowing what address or location on the disk to read/write.
I'm sure you could devise a way to do this, but it's not going to be straightforward :). I would do what you suggest and just use stdout via the serial tty.
