No upload happening.. #8

Really appreciate this detailed description of possible routes to go. I was able to upload once to this board over usb-c, not doing anything special. The second time I tried, I ran into the issue you describe.

My board came with a jst-connector, and I'm connecting pin 0 to gnd to get a boot switch. This makes my board show up on com23 instead of 22 when it's running the sketch. The problem is that nothing will upload. esptool just hangs after Serial port COM23, no errors, nothing.

I've tried pressing reset while boot is low, then releasing reset and lastly releasing boot. I've also tried holding boot the whole time while trying to upload.

CURRENT: upload_protocol = esptool Looking for upload port... Auto-detected: COM23 Forcing reset using 1200bps open/close on port COM23 Waiting for the new upload port... Uploading .pio\build\WT32-SC01-PLUS\firmware.bin esptool.py v4.5 Serial port COM23

Usually, releasing RESET then releasing BOOT works for me.

I'm on MacOS/Linux so I can't help with Windows -- be even on Linux the ESP 32 will show up as two serial devices and only one works. Can you switch back to COM22?
