Hi,
We need to understand how the software could readout temperature (level or level alert) from internal sensor/register on either the CPU or PMU to be able to shut down gracefully? Please provide documentation if this is possible.
Note: The OMAP4430 TRM (SWPU231AA, section 18.4.10) describes a very similar register (CONTROL_TEMP_SENSOR), and a table for converting the ADC readings to temperature ranges (18.4.10.2.3). Could it be that it’s the same band gap temperature sensor in the AM3874?
We see for instance BANDGAP0_CTRL/BANDGAP1_CTRL (page 666 in AM387x TRM, SPRUGZ7A)
Thanks.
