MIPS support for flash_can.py?

[pellcorp]

So I am using a cartographer on a K1, and so far we have never managed to figure out how to flash the cartographer on the K1. I suspect something needs to change in serialposix.py but I am unsure where to start looking.

So I know that Creality actually patched serialposix.py for the K1 build root already, and I am wondering if what they changed might provide some guidance?

I would appreciate any suggestions you might have, because this is what I am getting at the moment and its now locked up:

When I finally cancelled the flash, I got this stack trace:

Oh and cancelling corrupted katapult boot loader and I had to use DFU to reflash.
