I try to get an infrared led via gpio and lircd working. I used the armbian image with the 4.18 Kernel. With an rasberry pi it works perfektes…
please reference here :
There’s more information than getevent. I only find information related to Android and not Armbian.
According to this https://linux-sunxi.org/Linux_mainlining_effort#Status_Matrix onboard IR is not yet supported in a modern kernel.
