3 years ago Just for completeness: /sys/class/hwmon/hwmon0/temp1_input is affected as well, which is functional on 5.10.5 32-bit kernel. vcgencmd measure_temp works, but it would be good if at least one of the generic kernel tunables worked as well.

3 years ago Same problem exists on 3B, 3B+ and 3A running 5.10.7-v8+
A 3B running 5.10.7-v7+ works OK, so it's a 32 vs 64 bit error.

3 years ago I wonder if this is why the fan on my PoE hat does not work?
I re-installed the original kernel from the repo and fan is working again.

3 years ago I think the problem here is simply that the 3 and the 4 are sharing a kernel build, and that the arm64 bcm2711_defconfig does not include CONFIG_BCM2835_THERMAL=y. I can test the obvious fix tomorrow, but I thought I'd mention it now in case anyone else is in a position to try themselves.

3 years ago The obvious fix has been pushed to rpi-5.10.y and rpi-5.11.y, and will be in future kernel releases.
MichaIng
commented
3 years ago And I thought the RPi 3 is using https://github.com/raspberrypi/linux/blob/rpi-5.4.y/arch/arm64/configs/bcmrpi3_defconfig, but of course both use the same as there is only a single 64-bit kernel shipped, so all makes sense then 😄.
Just to remember where this has been changed initially:
I hope the two builtins do not interfere with each other. If there is more SoC-specific, it could make sense to build separate kernels by times. But to not ship 5 or more kernels for every model with the official DEB package, 32-bit and 64-bit should probably be separated first 😉.

3 years ago There's no possibility of interference - you've heard of Device Tree, haven't you 😉?
MichaIng
commented
3 years ago Okay, thanks for clarifying, yes of course I know about device trees, but I lack enough insights to be such about such things 😅. Thanks for the quick fix 👍.

commented
3 years ago A kernel with this fix is available via rpi-update.

3 years ago ok thx for the fix. Looks good.

Describe the bug Currently I'm not able to read CPU temperature on RPi3B+ while the exakt same image/sd card is working well on a RPi4B
To reproduce run
catonsys/class/thermal/thermal_zone0/tempExpected behaviour CPU temp should be displayed as it is on RPi4B
Actual behaviour temperature file could not be read
