I am running the following configuratoin
CPU: imx8mq (custom PCB)
Linux OS: Linux 4.9.123
I noticed the TMU generated temperature exceeded warnings and cutoff on power up. The critical temperature limit of 95C was tripped (the processors were nowhere near this temperature). I modified the trip-temperature to 125C and the device boots through u-boot and kernel and functions as intended (and has been working for weeks). Now, increasing the temperature is a temporary solution. What is the expectation in terms of calibration? I see there is a definition in the u-boot under "tmu" that looks like a calibration table. Is the expectation that we calibrate every unit?
