am3352 bandgap sensor dtemp

Other Parts Discussed in Thread: AM3352

Hi expert,

I want to get am3352 tempetature by reading the field "dtemp" in register "bandgap_ctrl".

The dtemp is "0x39" in normal case.

But sometimes the dtemp value I got is always "0x7F" and I am sure the temperature on am3352 is not over 100 c at that moment.

It seems that dtemp value does not change by environment temperature and dtemp value always keeps on "0x7F".

Do you know why or possible root cause?

thanks.
