Hi Steve,
Just curious, does your board have a heat sink on the SoC?

Assuming you are running the “release” build and bootloader - no - the
thermal control is overly aggressive until we tune it so you should not see any problems (however the cores may only run at 200MHz!).

Yes.
If use hisilicon bootloader + v3.18 kernel, the thermal driver with cpu cooling device has been enabled. So if the temperature > 70'c, the cpu frequency will be limited; and if temp > 90'c, the system will be reset, which this condition is hard to meet.
So suppose most case is to downgrade cpu frequency. If debug for performance issue, suggest to check cpufreq info.
A `make -j8 Image' kernel build on the board triggered the thermal reset mechanism for me, but that's the only time I've ran into it. (a less ambitious `make -j4 Image' worked fine).
Cheers,
