Abstract
In general, techniques are described for improving security of a boot sequence of an application processor. In some examples, a computing device includes a first processor coupled to a first storage device, the first processor and first storage device configured to obtain firmware from a storage device external to the first processor; run a verification routine on the firmware; and in response to validation of the firmware with the verification routine, communicate the firmware to a second processor; and the second processor coupled to a second storage device, the second processor and second storage device configured to load the firmware.
