PC Engines APU1: LEDs, buttons, temp sensor

Installing and Using OpenWrt
1

Hi
I just installed the openwrt-19.07.3-x86-64-combined-ext4.img on my PC Engines APU1d and it works OK.
But I have some issues:
I can´t get the leds and the push buttom to work and I can´t find package for the temp sensor, k10temp.

Any one how knows where to find the right packages?

Thanks

You might post your question on the forum of pcengines.ch
Anyway, when I remember correctly (read: no warranty), there were some patches posted there. Do not recall, whether patches for ubuntu or openwrt, though.

I have the lm-sensors package installed on an APU2. No k10temp or other temperature related packages AFAICT. But lm-sensors just shows the temperature:

root@PC Engines APU2:~# sensors 
fam15h_power-pci-00c4
Adapter: PCI adapter
power1:        2.60 mW (interval =   0.01 s, crit =   6.00 W)

k10temp-pci-00c3
Adapter: PCI adapter
temp1:        +54.5°C  (high = +70.0°C)
                       (crit = +105.0°C, hyst = +104.0°C)

For the LEDs there is a kernel driver available (kernel 5.4)

But at the moment there is no OpenWRT package available, so you need to compile your own OpenWRT image (master branch) with the right kernel driver option (LEDS_APU)
The button should work through an ACPI event i think -> needs a OpenWRT version with ACPI support

Thank!

It works.

root@OpenWrt:/etc/config# sensors
k10temp-pci-00c3
Adapter: PCI adapter
temp1:        +56.6°C  (high = +70.0°C)
                       (crit = +100.0°C, hyst = +97.0°C)

root@OpenWrt:/etc/config#

Hi
I´m a newbie to this. :slight_smile:
I don´t know how to create my own image. :frowning:

Thanks any way. I need to read and learn more.

kmod-leds-apu2

It is available in 19.07.3, but fell out of snapshot with the bump to kernel 5.x - I guess waiting for someone to fix it.... D'oh!

Edit- @mrhaav @kirdes @Borromini
Actually it disappeared with the bump to kernel 5.4.50. It is still present for the 5.4.48 build.

kmod-leds-apu2 was removed here:

but the new version did not get backported:

This module works only on APU2 boards, APU1 is different.
