wipy 3 - boot.py is not executed at starstup

karlito

Hello, the boot.py is not run at boot, only when i click on Run button in pimakr.

Can you help me ?

Artiom

It is 0.
It suddenly starts to work. So this one is solved for me.
Still thank you for code sniplets.

@artiom if you run the following commands:

from machine import Pin
p=Pin("P12", Pin.IN)
p.value()

What is returned? It should be 0.

Artiom

uos.listdir("/flash")
['main.py', 'sys', 'lib', 'cert', 'boot.py', 'test.py', 'project.pymakr']

It was downloaded then uploaded by Pymakr. So I expect it to be in the right place.

Firmware was updated today.

Its also important to make sure you have updated your WiPy 3.0 to the latest firmware. I faced similar issues that were fixed after updating.

@artiom Are you sure that boot.py is in the the directory /flash.
In the REPL prompt, issue the commans:

import uos
uos.listdir("/flash")

boot.py must be in the list returned by listdir()

Artiom

I have the same issue. My P12 is not connected to anything.

@karlito is by chance P12, also called G28 or GPIO21, connected to 3.3V? In that case the execution of boot.py and main.py is skipped.

karlito

And main.py is not run too at boot
