I am writing a software on a CPU without usable I/O (like physical serial port). for the debugging stage I would like to have some I/O (like printf to virtual console). Is there a way to do that, like the simulated serial port when using the simulator?
Thanks,
Izhar
"a CPU without usable I/O"
What CPU? Why the big secret?!
Does this CPU have on-board debug with JTAG or similar?
If there is no usable I/O then, by definition you have no way to get anything In to or Out of it, do you? That's what "I/O" means!
