<h2>Implementing your own UART / debug channel</h2> |
The first thing you need to do is to choose a debug channel for your |
hardware. This could be a UART, but it doesn't have to be. |
<p> |
Secondly you should write a small HDL module that interface between |
the ZPU memory map of debug channel to the UART. This should |
be relatively simple as all you need to do is to let the ZPU |
query the FIFO in/out for busy flag and allow the ZPU to read/write |
data to the UART via the memory map. |
