I install the LibreELEC-Odroid_C2.aarch64-8.0.0 release on my Odroid C2, and the module gpioplug-ir-recv is not present. So impossible to use the IR on GPIO.
I test with the IR on the board and that work, but is it possible to set the repeat timing?
It is not just the module: gpioplug-ir-recv missing. It is also the dependent module: modprobe options missing:
I see this error message, because wrxtasy incorporated the gpioplug-ir-recv into a LibreELEC 7.1.3 community testbuild successfully, but still the GPIO IR didn't work. So I saw that assignment of gpio_nr=238 wasn't possible because of the missing modprobe options module.
The thing here is... This thread is in the wrong subforum here. You refer to the official LibreELEC-Odroid_C2.aarch64-8.0.0 release, but this subforum here is only for the community builds.
