Could someone please guide me through how to disable REPL on UART0.
My thoughts: this could be a security vulnerability on your system when deployed as someone can easily plug in a USB cable and see everything in your system
Kindly assist.

Write in boot.py:

Code: Select all

from uos import dupterm
dupterm(None, 1)  # Disable REPL on UART(0)

But not ideal, if a hacker breaks the boot.py before this code, he can catch the REPR.
