Lastest esp32 library...some issues with Nodemcu boards

Postby dpcons » Sat Aug 20, 2022 6:47 pm

I'm using Arduino 1.8.19 with the latest ESP32 library 2.0.4. and Windows 11. I'm having trouble uploading to any of my esp32 nodemcu boards. Keep getting the error "Wrong Boot Mode" even though I manually prepare the board for loading. I've selected "ESP32 Dev Module". The compile and link go as expected, but I always get the error. I've tried various modules and different USB cables and the result is the same...Boot Error. Just as a test, I switched to the 1.0.6 ESP library and low and behold, the parts can be uploaded. I've still got "ESP32 Dev Module" selected an the same port and the upload goes OK. I've tried the latest library on another Windows 10 machine with the same bad results. I'll be trying it on my Linux machine when I get it configured. Am I doing something wrong? I'm dazed and confused.

Just an FYI. Version 2.0.1 works OK also. Linux machine works the same for both situations.
