Abstract: Technologies for updating a processing device, where a first device image is stored in a first (non-volatile) memory. When a new second device image is received via a communication interface, a first boot of the device is performed and a boot loader performs security processing on the second device image. Once security processing has passed, the second device image is set as a trial image and executed. The executed image is monitored to determine if predetermined operational parameters in the device are met. If the parameters are met, the second device image is set as a current image and the first device image is deactivated. A second boot is performed to make the new image operational for the device and the anti-rollback version one-time programmable fuses are blown. If the parameters are not met, the device revers to the first device image.

Abstract: Certain aspects of the present disclosure provide apparatus and techniques for configuring memory in an effort to reduce power consumption. For example, certain aspects of the present disclosure may provide an apparatus having a processing system configured to determine an operating mode of an application executing on the processing system. The operating mode may be one of a plurality of operating modes of the application, and each operating mode of the plurality of operating modes may correspond to a different configuration of memory. In certain aspects, the configurations of memory may correspond to different portions of memory that are active or inactive. In certain aspects, the apparatus may also include a memory control module configured to configure the memory based on the determined operating mode of the application.
