Can't find esp32 under /dev/
Can't find esp32 under /dev/
I have the ESP32 dev board from Adafruit, and I'm having trouble finding the serial port to the ESP32 under the /dev folder. I've tried pulling the EN pin high and low and tried following the directions in the getting started guide, but haven't had any luck. I have FTDI drivers installed too; never had a problem with this before. On Mac OS

That board doesn't use an FTDI. It uses a CP2102 chip. You can get the driver for macOS from silabs.com (look for VCP drivers).

I was in this same position and installed the Silicon Labs driver. I was then able to identify the port (/dev/tty.SLAB_USBtoUART). I hit an issue trying to flash the chip. A few weeks later a colleague suggested how to resolve the flashing issue, but when I go to try this, I find that the port is no longer visible. Restarting, reinstalling the driver etc. have not resolved this. What to do?

...are you using macOS High Sierra?- If yes: Have you looked in the "System Preferences" -> "Security & Privacy" settings under the "General" tab if the system has prevented the driver from loading?- If yes: You should find an "Allow" button there that you can use to allow the loading if you want (you have to have admin rights).
