Abstract: A microkernel-based operating system in a vehicle is initially operated in a first criticality mode of multiple supported criticality modes. In case a condition is determined that requires a transition to a second criticality mode of the multiple supported criticality modes, settings of the microkernel-based operating system are adapted in accordance with the second criticality mode. The microkernel-based operating system is then operated in the second criticality mode.

Abstract: The present invention relates to a method, to a computer program containing instructions and to an apparatus for performing a boot process for a system that supports redundant copies of boot images. In a first step, an active copy of the boot images is determined (S1). Then the active copy of the boot images is processed (S2). In response to a successful boot process, another copy of the boot images is then set (S3) as the active copy for a subsequent boot process.

Abstract: A flash memory device is re-partitioned over-the-air. A software component responsible for re-partitioning is received. The software component then generates a re-partitioning control structure in the flash memory device and executes re-partitioning steps. The executed re-partitioning steps and currently valid locations of data that needs to be moved in the flash memory device during re-partitioning are recorded in the re-partitioning control structure.

Abstract: Computer device(s), apparatus(es), and methods enable and/or perform interface independent test boot of a System on Chip (SoC). A test Direct Memory Access hardware unit (test DMA) and an Automatic Test Equipment (ATE) hardware unit suspend a processor core of the SoC, download a test case, perform a seamless switch into functional mode of the SoC, and execute the downloaded test case. The test DMA may mediate between the ATE and internal memory in the SoC.

Abstract: A processor includes logic to generate a wakeup code value for a deep sleep state in which the processor is powered down, store the wakeup code value to a first location in a power domain in which power is maintained in the deep sleep state, store the wakeup code value to a second location in a non-volatile memory device, and initiate entry into the deep sleep state. The processor also includes logic to begin execution of a wakeup sequence upon waking up from the deep sleep state. The wakeup sequence includes a determination of whether a value read from the second location and a value read from the first location match. If they do not match, the processor triggers an exception handling sequence, which may include a secure boot sequence. If they match, the processor continues executing the wakeup sequence without executing a secure boot sequence.

Abstract: A radio communication device and a method for booting a radio communication device are provided. The radio communication device can be configured to load an operating system code of a processor during execution of an authentication procedure code. For example, a first portion of the operating system code can be loaded, then the authentication procedure code can be loaded after the loading of the first portion of the operating system code. After the initiation of an authentication procedure that is based on the authentication procedure code, then a second portion of the operating system code can be loaded.
