...esptool.py erase_flash will completely wipe the broken filesystem, which is restored when you run the next deploy / write_flash.
I've corrupted a few filesystems by just using poor quality old usb cables. Easily fixed.

Re: Can Anyone Direct Me to I/O Serial Monitoring Example

* So essentailly, you want to replace the RPi by an ESP running micropython? Yes * The usb uart is not required as soon as your code is working right? User feedback could be disabled. :( The led on the relay is probably enough feedback. * It will be an autark system ... Automatic system I assume. * ...

Re: accessing uart0 on nodemcu board

If you write: uos.dupterm(None, 1) you disable the terminal output to UART so of course you dont see anything. Use the webrepl. Note known conflict between os.dupterm and WebREPL: https://forum.micropython.org/viewtopic.php?f=2&t=5446&hilit=WebREPL+Disconnected and maybe https://forum.micropython.o...
