Information on commissioning
Important note
By default, the Coral PCIe driver drives the Edge TPU with a maximum frequency of 500 MHz.
Under certain circumstances, continuous operation at this frequency can result in
overheating. The PCIe driver contains a dynamic frequency scaling that is activated by
default. The PCIe driver controls the operating frequency depending on the temperature of
the Edge TPU and can reset it to avoid permanent damage.
WARNING
Fire hazard due to overheating of the device
The TPU stops operation as soon as the operating temperature reaches 100 °C. Use the
given default values of the dynamic frequency scaling so that safe operation is ensured.
Otherwise, the Edge TPU and the surrounding components can get permanently damaged
and possibly cause a fire or other serious damage as well as injuries or death.
