now it was connected into WebIDE but got info that WebIDE can't find a stm32 bootloader, but pico is in bootloader mode, it is pulsing LED's,

after while It was possible to flash the firmware, pico can connect into WebIDE but I can't write anything in console, I have also Esprino board (green one) and it is working in all of that terminals,

dont' know what was wrong, but after plenty of times and few flash firmware operations It came back to live ;)

Glad it's sorted!

On Linux, you can get what you describe if some application is already connected to the com port - it happens if I accidentally leave minicom open in the background for instance.

Could it have been something like that?

Yes it could, I used some terminals as minicom and picocom, but I was worried I burned it as connected also NRF module and swap by mistake Vcc with GND, but fortunately pico is a live ;)

Formatting Help

Don't worry about formatting, just type in the text and we'll take care of making sense of it. We will auto-convert links, and if you put asterisks around words we will make them bold.

Tips:

Create headers by underlining text with ==== or ----

To *italicise* text put one asterisk each side of the word

To **bold** text put two asterisks each side of the word

Embed images by entering:

That's the hard one: exclamation, square brackets and then the URL to the image in brackets.

* Create lists by starting lines with asterisks

1. Create numbered lists by starting lines with a number and a dot

Just like Github, a blank line must precede a code block.
