Hey guys,
Environment; New Raspi 5, in a new Argon One V5 case. NVMe SSD is installed with Ubuntu, which will in the end be the running OS. However, under Ubuntu I wasn’t able to get the fans working with the Argon Service, so I am currently booting of an SD with Rasperry PiOS 32Bit trying to troubleshoot it. For the life of mine, I can’t get it working, nor is it visible under the i2cdetect when checking it. However, it seems to work, cause directly giving it commands via
pinctrl seems to work (proof & logs are at the end).
That points to me that the HW in general should be fine (all is newly purchased - Raspi, Case, SD and NVME). I’ve meanwhile tried as well 2 different SDs, Raspberry PiOs 32 & 64 Bit, Argonone service installed and removed, and it’s still not visible under the i2c. At the moment, Argononed is installed. Attached are a few config files, I would greatly appreciate it if somebody could point me towards a direction to get it working first under PiOS, so I could maybe port it in a way to Ubuntu.

/boot/firmware/config.txt file, mainly untouched on this SD, last few adjustments are shortly before the [CM4] part without luck.

I’m able to see a PWM FAN via pinctrl and start it as such;
tester@raspbi-joyit:~ $ sudo pinctrl | grep FAN
29: no pu | hi // FAN_TACH/GPIO29 = none
45: a0 pd | hi // FAN_PWM/GPIO45 = PWM1_CHAN3
When I manually start/stop it - it’s visible as well under the fan1_input as example;
tester@raspbi-joyit:~ $ cat /sys/devices/platform/cooling_fan/hwmon/*/fan1_input
0
tester@raspbi-joyit:~ $ sudo pinctrl FAN_PWM op dl
tester@raspbi-joyit:~ $ cat /sys/devices/platform/cooling_fan/hwmon/*/fan1_input

tester@raspbi-joyit:~ $ sudo pinctrl FAN_PWM op dh
tester@raspbi-joyit:~ $ cat /sys/devices/platform/cooling_fan/hwmon/*/fan1_input

Trying it via cur_state, doesn’t seem to work for me though, as it was described in this Post;

tester@raspbi-joyit:/sys/class/thermal/cooling_device0/subsystem/cooling_device0 $ echo "4" | sudo tee /sys/class/thermal/cooling_device0/cur_state

As well the comment that the OneV5 Case doesn’t work with the script but only with Kernel is additonally confusing me - is this somewhere published by Argon? As their official manual doesn’t mention anything and just instructs to install the Argon service.
In any case - Let me know if other log files are helpful, really would like to get the fan working properly - meaning it just gets active when it’s too hot .
Thanks!
