tmu_2_monitor_threshold#
Overview#
The TMU example shows how to configure TMU register to monitor and report the temperature from multiple temperature measurement sites strategically located on the chip.
The TMU has access to multiple temperature measurement sites strategically located on the chip. It monitors these sites and can signal an alarm if a programmed threshold is ever exceeded.
Supported Boards#
EVK-MIMX8MP
Hardware requirements
Micro USB cable
EVK-MIMX8M Plus board
J-Link Debug Probe
12V power supply
Personal Computer
Board settings
No special settings are required.
Please note this application can’t support running with Linux BSP!
Prepare the Demo
Connect 12V power supply and J-Link Debug Probe to the board, switch SW3 to power on the board
Connect a USB cable between the host PC and the J23 USB port on the target board.
Open a serial terminal with the following settings:
115200 baud rate
8 data bits
No parity
One stop bit
No flow control
Download the program to the target board.
Launch the debugger in your IDE to begin running the demo.
Running the demo
When the example runs successfully, you will see the temperature output from the terminal when the pre-set threshold is reached.
NOTE: Average temperature threshold is 50 celsius degree by default, you can modify this value to facilitate testing the effect!
