#4 K8055 card access not reliable with Kernel 4.4.26-v7+ - Raspberry Pi 3

[Erwan]

Hello
I have successfully compiled and installed k8055d on Raspberry running 4.4.26-v7+ kernel.

When accessing to /proc/k80555/0/outputs, result is displayed (0 or other curent value) and sometime nothing is returned. (se attached screenshot)
Also, when writing in inputs, despite the value is stored, sometime, the K8055 card does not receive it.

Conclusion: the access to the k8055 card is not reliable, it works ~80% of the time. Will it be possible to fix that (Linux kernel update ??)

Thanks
Erwan

I think I solved it.
Just uploaded version 0.2.2
It also contains a mini howto to build for the Raspberry Pi 2/3
