What is minimal requirement to have REPL running?

[xidameng]

Hi! I am currently working on porting micropython to a new board. I came to the stage where my firmware compilation was ok, safely uploaded and having logs printed, but just couldn't see REPL (three ">") running.

I am new to project of this magnitude and complexity, so any information or direction is truly appreciated!

I think that the minimal requirements are to have the heap initialized, and have the mp_hal functions related to the uart implemented.

This is essentially what the minimal port does: https://github.com/micropython/micropyt ... ts/minimal

Thanks ! !
Just as I suspected, I got heap and uart implemented, but haven't touched mp_hal... speaking of which, can you be a little more specific about the mp_hal function? I checked the "mphalport.h" file in the minimal folder, there is basically nothing there...

Thanks!!

Just as I suspected, I got heap and uart done, but not mp_hal function.. speaking of which, can you be a little more specific about the mp_hal functions? I looked into the minimal port folder and the "mphalport.h" contains barely anything..

Look at uart_core.c in the minimal port.
