I tried this image: https://rcn-ee.com/rootfs/bb.org/testing/2015-12-13/lxqt-4gb/bone-debian-8.2-lxqt-4gb-armhf-2015-12-13-4gb.img.xz
As I understand it this is the most recent jessie build.
Unfortunately on this image /sys/class/hwmon is not populated.
It is populated on the wheezy builds.
Do I need to install a package or kernel-module that solves this problem?
Or is there a fix in the pipeline?
TI deemed the internal temp sensor too "inaccurate" to push mainline..
Feel free to downgrae to 3.8.x if you need it:
sudo ./update_kernel.sh --bone-channel --stable
I did. Thanks.
Any chance this could be implemented by a third-party? Or is the TI-code a proprietary blob?
Yeah, it's easy to fix:
sudo ln -s /dev/urandom /sys/class/hwmon/temp_sensor
okay so it's not "that" bad.. But /dev/urandom is more 'consistent'...
But bad enough, TI hardware engineers told TI kernel developers to not
bother pushing it upstream.
This has been discussed previously on this list..
I know this has been discussed and I understand TI’s POV. I apologize if I seemed pushy or something. That is not my intention. It’s just that I currently see data coming from my BBB that seems reasonable, although slightly offset. There seems to be a nice correlation with changes in room-temperature too.
Anyway, it was just me wondering. Never mind. I’ll retire my code.
Thanks for the answer. Really appreciating your effort.
One can not help but wonder. Why have a “thing” at all, if it doesn’t work properly . . . and this isn’t the first “thing” on this SoC which doesn’t work properly . . .
