I would like to measure the temperature of SoC using TEMPMON and have some questions.
Please tell me the formula of Tmeans in i.MX7.
The calculation formula of Tmeas of p.4988 of i.MX7 RM Rev.1 is as below
On the other hand, the calculation formula of Linux source code is different.
Please see a line 585.
Which one is correct ?
If the Linux code is correct, please tell me the formula for calculating the temperature at i.MX7 like "Tmeans = ???”.
It seems to obtain the temperature using the calibration value in OCOTP_ANA1, but is OCOTP_ANA1 written at shipment?
Do we need to write the temperature by user ?
