Deactivate UART completely

Postby doglike » Tue Jun 30, 2020 10:08 pm

Hi,

I would like to have my esp32 pcb manufactured and make the first flash myself.
All other flashes only happen OTA.

So for security reasons I want to deactivate UART completely with die firmware, that will be flashed @ first flash.
Can you guys give me a hint, how I can do this?

Thanks in advance!

PS: During developing/testing a could reactivate UART again in my firmware and flash that firmware OTA, so I think that UART should be working again...
