Ooh, I had forgotten to pull pin 8 up, and now it looks like it connects and recognizes the chip correctly, but it fails to upload with the following error:
----

Serial port /dev/ttyUSB1:

I'll keep poking at it...

@bipolaron@scholar.social I was able to find a log from within the chip during programming that showed that it was resetting whenever I tried to program it. Found this person had a similar constant reboot problem and he removed the capacitor between the crystal and XTAL_P and it worked for them. https://esp32.com/viewtopic.php?t=30627 I tried popping off this capacitor on mine, and it programmed correctly and even got the right hash check after programming. Now, I'm trying to get it to reboot into normal mode...
