Support for Raspberry PI 4

[anITiot]

Hi, I'm running Ubuntu 18.04 64bit on my RPI4 and the processor seems to be unsupported.

[vielmetti]

Also the case under Ubuntu 20.04 64bit on the Pi 4.

sensors command returns this:

emv@pinnatus:~$ sensors
rpi_volt-isa-0000
Adapter: ISA adapter
in0:              N/A  

whereas Ubuntu 20.04 64-bit on the Pi 3 return this

ubuntu@ubuntu:/sys/class/thermal/thermal_zone0$ sensors
cpu_thermal-virtual-0
Adapter: Virtual device
temp1:        +52.1°C  

rpi_volt-isa-0000
Adapter: ISA adapter
in0:              N/A  

[sg3524]

Verifying what @vielmetti has already reported. Under 20.04 I am seeing this

$ sensors
cpu_thermal-virtual-0
Adapter: Virtual device
temp1:        +43.3°C  

rpi_volt-isa-0000
Adapter: ISA adapter
in0:              N/A

It's now more than 2 years since that report has been created.
Is there any hope that the maintainers of lm-sensors will take action within a few weeks or should I look for other solutions?

Nothing will be done in lm-sensors, as this is a kernel issue. lm-sensors only displays what is exported by the kernel in /sys.

The problem has been solved with the following commit of kernel 5.6: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=59b781352dc4cb9ae27a8ddae0cda979d29d8af7

This bug should just be closed.

I still have same issue.

It seems that the thermal sensor driver for the SoC on Raspberry Pi 4B doesn't work according to previous comments under this issue.

The problem has been solved with the following commit of kernel 5.6: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=59b781352dc4cb9ae27a8ddae0cda979d29d8af7

That link only handles the thermal problem, not the "rpi_volt-isa-0000"

[Lin-Admin]

Linux R 5.15.0-1023-raspi #25-Ubuntu SMP still does not handle "rpi_volt-isa-0000".
Maybe this is relied to the dmesg warning usb_phy_generic phy: supply vcc not found, using dummy regulator?

[twisted-nematic57]

also not working under Ubuntu 22.04 Server LTS (aarch64 raspi 4 8gb ram)

The same on the latest Rocky:

[root@node01 ~]# sensors

Same issue on Fedora 39.
