ESP32 Forum

I had some custom PCBs made with ESP-WROOM-32E. I first had trouble with boot mode, because IO0 didn't seem to be held high, so I added an external pull up to fix that.

Anyone else run into this?

Well the external pullup shouldn't hurt. I put it by default on my design and I can flash fine, but I'm having problems because the flashed program won't run for very long. I've posted that in another thread. Waiting for it ot be approved.
