Hello,

I want to calibrate the thermal sensor for the imx8mm. I read the i.MX 8M Mini Applications Processor
Reference Manual chapter 5.4 Thermal Monitoring Unit (TMU).

I can't find information about the calibration register for the TE1/TE2 value. All the information I found in the chapter are 8-bit data stored in OTP cells. How is the name of the register?

Do you have an application note, which described the temperature calibration on production test?

I ask because we have our own customer board and want to calibrate the thermal sensor.

Hi, It came calibrated, but Thermal driver is a necessary driver for monitoring and protecting the SoC. The thermal
driver will monitor the SoC temperature in a certain frequency.

Regards

Do you know, if I have to calibrate the thermal sensor?

I ask because we get only an imx8mm SOC not a board with the SOC. Do I have to calibrate the SOC or is the SOC calibrated?

Hello Sebastian,

Seems details can be found only in sources of thermal drivers described in

sect.2.9.3 Source Code Structure of the  Linux reference Manual of the BSP.
