Tool/software: Linux
Hi TI guys,
Our customer Harman used TI SOC ''DRA755BLH3ABCRQ1'' to develop CPU module product.
The linux kernel version our customer used was 4.4.14.
Our test application is based on linux kernel 4.4.14.
We found one issue when the temperature at < -30°C.
The TI kernel thermal driver would show error message of failed to read out thermal zone (-5) sometimes when the temperature at < -30°C.
Could you let us know how this issue happened?
The following is the error message when the temperature at < -30°C.
[ 186.315226] thermal thermal_zone4: failed to read out thermal zone (-5)
[ 186.375261] thermal thermal_zone2: failed to read out thermal zone (-5)
