Notice. New forum software under development. It's going to miss a few functions and look a bit ugly for a while, but I'm working on it full time now as the old forum was too unstable. Couple days, all good. If you notice any issues, please contact me.

This is a clone RP2040. Been working perfectly for months.

I am programming it daily, never a hiccup.

Now wanting to load new firmware using the usual routine but the folder doesn't show up for me to deposit the uf2 file.

Tried powering everything down and also switching from the USB port on my hub to a USB port on the W11 mini PC. Nothing.

Anyone seen this before?

Hm.., maybe because of the clone?

I know a lot of people like those clones since they often have more flash or other benefits. Personally I would never use them because you can't be sure if (apart from the RP2040) the parts are genuine... (+ built quality isn't that good).

Compare the original pico board(s) with the clones... massive (!) difference. And this _could_ apply to the parts, too.

Did you checked the BOOT button? Maybe it is broken...? Bad contact? Easy to check..

Edit: But to mention a good company with high quality and all original parts: Adafruit.

The device appears to be in the BOOT mode because it becomes unavailable to the terminal. It's like the PC isn't getting the instruction to have the virtual drive pop-up.

Ah-ha...It IS the PC. Just tried the device with my old XP machine and that works fine.

Not too long ago, I messed with Zadig drivers so I could use Picotool. I wonder if the problem is related(?)
