pico isnt connecting to thonny

[UmutDemirel06]

Hi ı am very new in this community ı am trying to code my pico using thonny but it gives a weird error






as you can see ı tried to follow the most common way

After uploading micropython, you need to disconnect the pico to take it out of bootloader mode, then connect it again.

pico does that on its own but it still same

Recently I put a new micropython on my picoW and, after disconnecting it and reconnecting it and trying to connect to it to Thonny (which was running on an rpi4) I got a similar situation. Also I have found that instead of selecting 'Try to detect port automatically' I get a more reliable connection if I use the dropdown to select the port. However, In my case, selecting the port shown in the drop down still did not work. I tried closing Thonny and executing it again, but still not luck, so I then tried the more brutal tactic of rebooting the rpi4. When it was back up the Thonny drop down then showed a choice of 3 ports and by selecting the newly showing port I was back in business with my pico. - So a long spiel to suggest you try a reboot !

ı would appreciate it if you could recommend a source for rebooting pico

@Hopesforgypsy - I was referring to rebooting the computer on which Thonny was running, in my case an rpi4. As regards the pico, disconnecting it from a power source will do the trick.

oh well i tried that but it didnt change anything

I think, from looking at your original post, you were downloading mp to the pico via Thonny. I suggest you download the latest mp directly from their web site, and copy it onto you pico. (get your pico ready by holding the bootsel button down whilst applying the power) When you've copied the latest to the pico, disconnect pico from power, reconnect it to your computer that runs Thonny, fire up Thonny and hopefully you should be in business.

i think the problem might be related to the computer i am using because pico doesn't appear as a com device

This is a wild guess, but... I think it is worth trying it.

Disconnect your Pico from the USB port and any USB-Serial device you have.

Have Device Manager show hidden devices

Delete all shaded devices that appear (COM5, COM6 etc.).

Do not check "Exclude driver for this device" for the time being. Connect your Pico. It should be recognized as COM5. If it does not, then try excluding the driver this time. If it does not work, then I have no idea what is happening. My next troubleshooting step would be booting this PC with a USB flash drive with a live Ubuntu distribution and try to see if your pico is recognized (as ttyUSB0 or, maybe ttyACM0).

lemme try this too

well it seems like i need to do that ubuntu thing can you explain a little more

If you are not familiar with Linux, then it is not a good approach. My next one would be trying your Pico on a friend's PC and see with Device Manager if it is recognized.

yeah ı will try that tomorrow if its because of my computer i will inform you guys

Yes, the bit you show on your screen dump is what is on your Thonny computer, you need to scroll down to see what, if anything, in on the pico. It will be below the thick bar on the bottom of your dump

[UmutDemirel06]

there seems to be nothing

[beetlegigg]

And just to check that you have hit Thonny's big red stop button a few times. When you first connect your pico make sure you are seeing the REPL and its showing the version of micropython you are using, and on program failures the stop/restart button may need to be hit.

[UmutDemirel06]

that ı wanted ask as well repl menu isnt there

[UmutDemirel06]

ı was able to run blink in Arduino ide but that's about it ı couldn't get output in any way so ı tried to use thonny but that didn't upload anything to pico

[beetlegigg]

I think that if you run Arduino C++ on your pico you zap the micropython which will probably mean you need to reload mp. This was certainly the case when using the Arduino IDE on an adafruit feather board with mp installed. Arduino and micropython do not mix well.
Just in case something on you pico is upsetting things you could put the flash_nuke.uf2 onto the pico before yet again reloading the mp.uf2 file. The nuke will mean any files you may have put on the pico will be zapped as well as the mp.
Other that that you could try to see what happens if you load a previous version of Thonny to you PC, but Thonny 4.1 works well for me (though I dont use a PC, only mac and rpi4) I cant think of anything else to suggest. I've been putting mp on my pico's (some 15 of the blighters) and updating them without many issues apart for some initial connecting issues I mentioned in my first post. Maybe its time to pause, have a cuppa, carefully read the rpi micropython installation instructions from the rpi micropython software developers kit documentation, and trying again from scratch. Sorry not to have better suggestions for you.

no worries man ıve been fighting with this problem for about a week ı even bought a new pico but it didn't work as well
