Multiple trouble on first setup

Support

Hi,

I wonder if somebody could help me.
The unit just arrived and it is assembled.

I connected to the computer (win and linux), opened the Brave browse, gone to https://xrpcode.wpi.edu/ I click connect selet the device.

It tells me that MicroPython needs to be updated.

UF2 Bootloader v3.0
Model: Raspberry Pi RP2
Board-ID: RPI-RP2

The version now is MicroPython v1.19.1-859-g41ed01f13 on 2023-02-09; Raspberry Pi Pico W with RP2040

I click OK.
There is a popup with some cryptic text about a disk drive and select “Edit files”…
I click OK.
Update in progress… Updating MicroPython … 3%
and I’m stuck forever. A disk drive pops up with two files, serial device is gone. Nothing happens further.

After some back and forth with windows with linux… one time I skipped the step. Now it wanted to update the libs. It succeeded.

After that I was able to run the verification code on the device and

  • led works
  • line seems to work
  • range works
  • servo just makes small clicking sound
  • drivetrain goes a bit forward and the it goes around endlessly.
    and
  • can’t update micropython.

Please help!

Only remaining problem is the stepper. It makes little to no movement and I just hear a faint clicking sound.

Okay. So based on this site: https://projects.raspberrypi.org/en/projects/get-started-pico-w/1
I was able to put new MicroPython on the controller… so upgrade is done. I would like to see some step by step guide for upgrades. It is for me really confusing.

Drivetrain need to be grounded. On the air the robot never turns 90 degree… After I placed it to the ground it did what is should.

Make sure the motors are on the correct ports on the boards – I accidentally connected one motor to the wrong port. Make sure you’re using fresh batteries – this is a common cause of weird problems.

Your micropython version should be MicroPython v1.24.1 on 2024-11-29; Raspberry Pi Pico W with RP2040
