Cannot read from AMD Chips

[Candunc]

Compiled for Ubuntu Server 12.04, the default shows 40 C, while the built in /sys/bus/pci/drivers/k8temp/0000:00:18.3/temp1_input doesn't seem to be supported.

I made sure to change it to /sys/bus/pci/drivers/k8temp/0000:00:18.3/temp1_input to keep it from crashing, however it doesn't read the temps:

Cannot read sensor data at /sys/bus/pci/drivers/k8temp/0000:00:18.3/temp1_input: open /sys/bus/pci/drivers/k8temp/0000:00:18.3/temp1_input: no such file or directory.

Using the command 'cat /sys/bus/pci/drivers/k8temp/0000:00:18.3/temp1_input' from the command line works, what could be the problem?

Hi there,
If you use Groundcontrol outside of a Raspberry Pi, then you might hit unexpected issues. I'm not familiar with this sensor to great depth, but what you can verify is that it is readable in a "file-like" fasion from Groundcontrol (check permissions), by trying a cat your-file.
The result should be something like 47345 to indicate 47.345 centigrade.
Hope this helps

Thanks, no idea what the main issue was but this is easily fixed by creating an alias to the file.
The workaround is simply using the command sudo ln -s /sys/bus/pci/drivers/k8temp/0000:00:18.3/temp1_input ~/temp for example, then Groundcontrol will read it properly after you change the file location to /home/[username]/temp

yep sorry I had that in my mind but eventually it didn't jump into writing 👍
