If there is a USB device attached on USB host connector and consumes power a lot, the board might not be booted because the CPU can not be provided enough current. In order to prevent boot failure in such case, especially a USB device consumes a current more than 1A, we strongly recommend to keep providing power through DC jack. | If there is a USB device attached on USB host connector and consumes power a lot, the board might not be booted because the CPU can not be provided enough current.
