Hi, Think I've found what the problem is. RPi.GPIO edge detection relies on sysfs GPIO, which is deprecated since kernel 4.8 (i believe) : https://www.kernel.org/doc/html/latest/admin-guide/gpio/sysfs.html I've read that it'll be removed in 20 20 ; i.e. about tomorrow. And it turns out that alpine linux 3.11.2 dropped support of sysfs gpio in their kernel. Any plan to move RPi.GPIO on to the new character-device-gpio approach ? David

edge detection no longer working on Alpine linux 3.11.2 (kernel 5.4)
