when i reboot my esp32, in the REPL it shows the error mentioned in the title. when i was following the tutorial to "getting started" with uPython on the esp32, i didnt notice anything that mentioned a "menu config". how would i go about accessing this menu, and changing the configured chip revision?
if it is important, this is the name of the firmware that i flashed to the esp32:
esp32-idf3-20191122-v1.11-586-g1530fda9c.bin

This is just an informative warning, safe to ignore.

Menuconfig is part of the SDK that you use when writing ESP32 firmware in C. If you want to provide a custom board config for MicroPython, you can override this setting (Tinypico does this for example)

OH! ok, i think i remember seeing somewhere now. like when compiling a custom Linux kernel, you (eventually) use `make menuconfig`.
thanks!
