@johannesthoma l tested the kernel module using Ostro OS, Since Ostro is using kernel 4.4, there are several changes, the build failed fatal error: linux/iio/sw_trigger.h: No such file or directory,...

@johannesthoma Thanks for your update! I am using the linux-yocto-dev: git://git.yoctoproject.org/linux-yocto-dev. I have a Pi 3 board, let me test it using it too.

Thanks @johannesthoma. When you tested the linux-yocto-dev kernel, did you connected the hardware? Since the linux-yocto-dev is changing, let me re-test it using 248edfa0de0fce4f4e88a8d9a0ccc326ac532fa9

@johannesthoma Since it is not hardware related, let me test it using my Pi3 and Minnowmax boards. I am in Shanghai China, GMT+8
