Again -- MMM-Navigate can't get installed.

@rkorell finally I got it solved :)

The issue is really the GPIO numbering, I found this SO thread:
https://stackoverflow.com/questions/78173749/use-raspberry-pi-4-gpio-with-node-js
It is also valid for Pi3 and Pi2

cat /sys/kernel/debug/gpio

gpiochip0: GPIOs 512-565, parent: platform/3f200000.gpio, pinctrl-bcm2835:
 gpio-512 (ID_SDA              )
 gpio-513 (ID_SCL              )
 gpio-514 (GPIO2               )
 gpio-515 (GPIO3               )
 gpio-516 (GPIO4               )
 gpio-517 (GPIO5               )
 gpio-518 (GPIO6               )
 gpio-519 (GPIO7               |spi0 CS1            ) out hi ACTIVE LOW
 gpio-520 (GPIO8               |spi0 CS0            ) out hi ACTIVE LOW
 gpio-521 (GPIO9               )
 gpio-522 (GPIO10              )
 gpio-523 (GPIO11              )
 gpio-524 (GPIO12              )
 gpio-525 (GPIO13              )
 gpio-526 (GPIO14              )
 gpio-527 (GPIO15              )
 gpio-528 (GPIO16              )
 gpio-529 (GPIO17              |sysfs               ) in  hi IRQ
 gpio-530 (GPIO18              )
 gpio-531 (GPIO19              )
 gpio-532 (GPIO20              )
 gpio-533 (GPIO21              )
 gpio-534 (GPIO22              |sysfs               ) in  hi IRQ
 gpio-535 (GPIO23              )
 gpio-536 (GPIO24              )
 gpio-537 (GPIO25              )
 gpio-538 (GPIO26              )
 gpio-539 (GPIO27              |sysfs               ) in  hi IRQ

I needed to set up the numbers according to the output
e.g. Pin27 is 539 in the MMM-Navigate config.
Now everything works so far as expected, thank you all for your help!

@crowimu COOL!
congratulations!

For me the “confusing” part was the fact that INSTALL doesn’t work…
Installing should NOT check GPIO pinouts …

Really great that you worked this out!

Warmest regards,
Ralf

A Pi4 or a Pi5 had solved this as well :-)

@rkorell because MagicMirror is started with the electron binary, the compiled module code must match the engine version

electron rebuild does that.

tricky problem if not running under electron
then npm rebuild works for nodejs engine match

OK, sounds plausible.
Thanks.

Learned a lot, today :-)
