5.1 Usage Notes

i001: The board can reset during boot and/or normal use.

Details: This can be due to insufficient power supply providing power to the SK (via the Type C connector). Make sure the external supply meets the requirements detailed in Section 2 of this document. If the supply has multiple output options and/or connections, make sure the correct option is selected that enables the input supply to negotiate to the recommended voltage (20V). Operating from a 5V input will likely limit the available processing power and could be a cause of the board resetting under boot/normal conditions.
