M5Stack Fire - Error when selecting the way to program it

Carles B.

I just received my M5Stack Fire and I have mistakenly clicked on UIFlow Setup and have not found a way to override it. I want to program it with Arduino and every time I connect it, it asks me to finish the UIFlow configuration. How can I fix it?

Thank you in advance

It comes with uiFlow firmware from the factory. If you want to use Arduino, just flash any relevant Arduino sketch to it (like from the Examples) and it will erase the uiFlow (MicroPython) firmware. Just make sure your Arduino libs are up to date with the latest M5Stack libs. To get back to uiFlow in the future, use M5Burner.

Hi @world101,

When compiling Hello World I get an error:
Pyserial is not installed for /usr/bin/python. Check the README for installation instructions.
Traceback (most recent call last):
File "/Users/carles/Library/Arduino15/packages/m5stack/tools/esptool_py/3.0.0/esptool.py", line 39, in <module>
import serial
ImportError: No module named serial
.......
exit status 1
Error compilando para la tarjeta M5Stack-FIRE.

According to the terminal it is installed in phyton3:
MacBookPro:~ carles$ python -m pip --version
/usr/bin/python: No module named pip
MacBookPro:~ carles$ python3 -m pip --version
pip 20.2.3 from /Library/Frameworks/Python.framework/Versions/3.9/lib/python3.9/site-packages/pip (python 3.9)

There is an easy solution.

Thank you in advance

Have you followed the quick start guide for programming with Arduino?

@world101

Yes. I am going to mount a newer version of MacOs on an external drive. I think the problem comes because there are two versions of python, I'll discuss it later

I’m not on Mac OS BigSur yet, but if you are, then the following thread might help you.

Thank you for your interest. I have placed the version before BigSur, Catalina, which gives me the same error. I will try the solution from your link. If I can't solve it I will put the post in the software section.

Hello @world101,

Solved. In the post https://community.m5stack.com/topic/2521/v1-0-6-of-board-manager-not-working-solved the solution given by @lidericc works properly

Great. Glad you got it sorted out and can begin enjoying M5Stack 😀
