DTS internal peripheral

Template:ArticleMainWriter Template:ArticleApprovedVersion

1 Peripheral overview

The DTS peripheral is used to monitor the device temperature and take some preventive action (like frequency scaling or peripheral disabling) in case it is becoming too high and before destroying the component.

1.1 Features

Refer to the STM32MP15 reference manuals for the complete list of features , and to the software components, introduced below, to see which features are implemented.

1.2 Security support

The DTS is a non secure peripheral.

2 Peripheral usage and associated software

2.1 Boot time

DTS is not used at boot time.

2.2 Runtime

2.2.1 Overview

The device cannot warm up if the Cortex^®-M4 is running alone, as a consequence the monitoring is only done from the Cortex-A7 non-secure context with Linux^® thermal management framework.

2.2.3 Peripheral configuration

The configuration is applied by the firmware running in the context to which the peripheral is assigned. The configuration can be done alone via the STM32CubeMX tool for all internal peripherals, and then manually completed (particularly for external peripherals), according to the information given in the corresponding software framework article.
