Got excited about this project and ordered two. Tried the first couple of examples but got following error. any ideas? both are doing same thing on all two of my devices. Thanks

Changed the Flash mode to DIO from QIO, and now I get different error.

Not sure what is up with this. Have you gone through the Troubleshooting steps?

dkim777 commented 8 months ago

Thanks for the troubleshooting step. You might want to add following.

You may need to put the device into download mode by press and hold "BOOT" and click "RESET" to change mode to download and then press and hold when you see "Connecting ........" after the compile to properly upload the code.

not sure why but above method works, it won't just flash like other esp32 devices.
