Hi experts,
I used ADC_getTemperatureC() function in CPU2 to calculate the internal temperature, and found the result was incorrect. This function uses the offset and slope parameters stored in the TI OTP area, but I found that the contents of the TI OTP can only be read by CPU1, and CPU2 can read all zeros.
Is the TI OTP area only accessible by CPU1? If so, does that mean I need to pass these parameters to CPU2 in some other way before I can do the temperature calculation in CPU2?

Shwan
Hi Shawn,
Yes, you would have to pass the OTP values for temp sensor from CPU1 to CPU2 in order to do proper calculation. CPU2 does not have access to the OTP locations where the temp sensor slope and offset are stored.
