Sir, I'm stuck on the "stub running" prompt and it's not moving ahead. Can you please suggest a resolution?

Can you help me with this. I have esp32 s2 pico, when plugged to the power supply led on the board was working. After installing arduino ide and trying to make it work, led was off and pc wouldnt recognize it. So I did hold boot, press reset and release boot. After that pc reacted and I could only do arduino ide example get chip id. There is still no light from the board and I couldnt even do basic blink with a led. Tried some methods and again it doesnt give signs of life when plugged to pc or to external power supply.

Didn't work at all. Clicking on connect immediately pops up "Connected to device: null".

[yashodabhavani]

Erasing flash (this may take a while)...

When I try loading it on esp tool it says error failed to execute open on serial port. Failed to open serial port. Please help!!

If u have this error: upload on board on Arduino IDE but on terminal it appears rebooting E (3XX) core flash corrupted.
Solution for Arduino IDE users: turn the version of the esp32 board library from to 3.0.2 and it will solve the issue of constantly rebooting in the terminal. 21 jul 2024
