M5Burner is made for 32 bit or 64bit X86 based system. Raspberry pi's use an arm based system and so M5Burner is not compatible.
What you are seeing is the "Factory demo" that comes preinstalled.
I set up My RPI4B to look into it and got distracted and so haven't got very far.
I need to update the firmware for one of the Stick C Plus apps I made., and I cannot login to the M5Burner from Windows or Linux. Linux tells me it's receiving a 504 error which is usually a CDN or reverse proxy timing out.
I was looking for this for 2 hours and after posting I found a solution by chance after 5 min.
I will leave this with my solution if someone have the same problem later.
this page show how it is done in python:
now I started trying to find any function in UIflow that could replicate this and...
"bytearray in list xxx get sub-list from # to #" actually writes this code!
Hmm, so that means I can not use any of Grove connectors for this? I tried with the other hint provided about alternatives, but don't get it to work... Sounds like I need to sent back the Fire and get another M5Stack Core version?
