Fedora ARM mailing list,
I've been trying to get the fan on my Raspberry Pi PoE HAT working with Fedora 35 and 36 Beta. I'm using the aarch64 raw image.
I came across the instructions on the wiki page here: https://fedoraproject.org/wiki/Architectures/ARM/Raspberry_Pi/HATs#PoE_Hat
Unfortunately, the line in config.txt from the wiki didn't work for me.
The lines that did work on Fedora 36 Beta for aarch64 are below:
dtoverlay=i2c
dtoverlay=pwm-raspberrypi-poe
I'm also able to set the fan parameters with the below:
dtparam=poe_fan_temp0=70000,poe_fan_temp0_hyst=10000
dtparam=poe_fan_temp1=60000,poe_fan_temp1_hyst=10000
dtparam=poe_fan_temp2=50000,poe_fan_temp2_hyst=10000
dtparam=poe_fan_temp3=40000,poe_fan_temp3_hyst=10000
Note that these same lines didn't work for me on Fedora 35 aarch64.
I'm hoping others can replicate my experience and the wiki can be updated to help others.
Please let me know if you have any questions or concerns.
