Note: Please ensure jumper settings are set accordingly prior to powering up the system to
prevent back charging the on board power supply circuitry.
Apart from the input power source, different boot configurations can be set on the Open-Q™ 605
SBC. Table 3-4 refers to the various jumper settings that are available for different boot options.
Please note that the only boot from eMMC is supported by current BSP. Please contact Intrinsyc
