HI

I can't display nagative temperature properly.

in the chamber, positive value looks reasonable, but nagative temperature value looks wrong.


When I print temparatue using read_cpu_temperature() in uboot in -35C champer.

it print as following

 

   cpu temperature : -56.51 C

Invalid temperature reading

 

Imx6q doesn't support nagative temperature value?

How can I read correct navative temperature value?

 

Thanks

seungik lee.
