Board was working fine until it started to give me this error:

Other times the error is:

How can I reset it? I have trying different cables, sketches, settings, everything but no success.

I have tried it so many times without success (hold the Boot button, connect the USB cable, press RESET, release Boot, release Reset). I have noticed that the board time changes from ESP32S3 Dev module to u-blox NORA-W10.

lewisxhe commented 1 year ago

No, insert USB, press and hold BOOT, do not release the boot button, then press RST. Finally, release the boot

I am probably doing something wrong:

I open Arduino IDE with my sketch
I select board ESP32S3 Dev Module
No serial port is select yet because the board is not connected
I connect the board via the USB cable
I press and hold the BOOT button
While still pressing the BOOT button, I press RST
I release the BOOT button
I release the RST - when should I do that?
Board shows in Arduino IDE as u-blox NORA-W10 and auto-captures a serial port (cu.usbmodem223401)
I run the code and get the same error message again :(

connect the board via the USB - cable
press and hold the BOOT button While still pressing the BOOT button, press RST 3.release the RST 4.release the BOOT button

You are the best! Thank you!

For you that arrived here via search engines: are you stuck in this loop?

The quoted message is the solution! This finally worked for me, thanks

Thank you, thank you! The Boot - reset - release worked for me too!

Awesome! It worked for me too.
Its strange that this problem just presented itself and has occurred with multiple esp32-s3 xiao units, Even sending the basic 'blink' program had the issue. Smells like a windows update problem. The problem started after an update, Hmmm.

Update....After some more testing I discovered the error occurred with both esp32s3 and esp32c3 boards. I checked for windows updates and there was one available. The update included a BIOS update too, but that is probably just a Dell thing. Either way....after installing the update the problem has completely disappeared.
