Hi! I've been working on the Pico connection all day. First in Windows 10 in Thonny. Now in RaspberryOS also in Thonny. Let me error.
Code: Select all
Traceback (most recent call last):
File "/usr/lib/python3/dist-packages/thonny/workbench.py", line 1708, in event_generate
handler(event)
File "/usr/lib/python3/dist-packages/thonny/shell.py", line 433, in _handle_program_output
self._update_visible_io(None)
File "/usr/lib/python3/dist-packages/thonny/shell.py", line 512, in _update_visible_io
self._apply_io_event(data, stream_name)
File "/usr/lib/python3/dist-packages/thonny/shell.py", line 555, in _apply_io_event
self.active_extra_tags.pop()
IndexError: pop from empty list
I connected the Raspberry Pico to the computer as described. You must first hold down the BOOTSEL key and then download the uf2 file. However, an error still occurs.
Thank you for your help and response.

When you have downloaded the .uf2 file once, there is not need to do that again, unless you want to change tht firmware. What happens if you connect the device without pushing the bootsel button. Then it should be in normal operation mode.

This occurs during normal startup. Then I installed a new uf2 file.
I also uploaded a new file
rp2-pico-20210418-v1.15.uf2 but without success.
But I got on this page.
https://www.micropython.org/download/rp2-pico/.
I don't know what else to do.
Thank you for your help and response.

To be sure, that the Pico works fine, try using a simple terminal emulator like Putty (Windows) or picocom (Raspi).

Great! I connected to the picocom and noticed that it was running in the second core of the program in the background. I stopped him. Now it works great through Thonny. Thanks!
