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

Hi, Lee
Can you tell me which uboot version you used, v2009 or v2013? I can NOT see any log like "Invalid temperature reading" in our uboot. It can be the temperature you read is out of our valid range, we only support -40C ~ 125C. Can you try to adjust the champer's temp to -15C?
Oops it's been a long time.
Sorry I missed your reply until now.
I use v2009 uboot.
Next time I will check temperature at -15C then continue.
Thanks
no problem.
But I am still very confused about the log you got, we never have such log"Invalid temperature reading" in our uboot, are you sure you are using our imx_v2009.08 uboot or you port our code into your own platform?
