The temperature registers provide the current, maximum (from power-up) and minimum (from power-up) for the processor and PCB for Zynq processor.
These registers are only available on Xilinx Generation 5 platforms, and are periodically populated by the motherboard core application, which only runs in Petalinux and BareMetal. For other operating systems, refer to the naibrd Software Support Kit (SSK) naibsp_system_Monitor_Temperature_Get() routine to manually retrieve the temperature (NOTE: this feature is typically utilized for development/factory use only; contact the factory for additional details on potential use, if required).
Temperature Readings Register
Function:
Specifies the Measured Temperatures on Motherboard.
Type:
signed byte (8-bits) for each temperature reading - Six (6) 32-bit words
Data Range:
0x0000 0000 to 0xFFFF 0000
Read/Write:
R
Initialized Value:
Value corresponding to the measured temperatures based on the table below.
Operational Settings:
The 8-bit temperature readings are signed bytes. For example, if the following register contains the value 0x6955 0000:
