Abstract: Systems and methods are provided for enabling an over-the-air update to a plurality of vehicles. A system and method include transmitting a wakeup signal over a communication network to the vehicles that are in a listen state. The update is transmitted over the Wi-Fi network to the vehicles. The transmitting of the update over the Wi-Fi network includes using a transmission scheme to overcome asynchronous communication wakeup of the vehicles.

Abstract: A method of re-programming flash memory of a computing device is presented here. Software content having a plurality of software modules can be re-programmed by identifying, from the software modules, a first set of software modules to be programmed by delta programming and a second set of software modules to be programmed by non-delta programming. A first set of sectors of the flash memory is assigned for programming the first set of software modules, and a second set of sectors is assigned for programming the second set of software modules. At least some of the second set of sectors are designated as temporary backup memory space. The first set of sectors is programmed with the first set of software modules, using delta programming and the designated temporary backup memory space. After programming the first set of sectors, the second set of sectors is programmed with the second set of software modules, using non-delta programming.

Abstract: Methods and systems are provided for bypassing an authenticity check for a secure control module. In one embodiment, a method includes: receiving authenticity data from a secure source, wherein the authenticity data includes a signature and an identifier that is unique to the control module; programming the control module with the authenticity data; and bypassing the authenticity check of a control program of the control module based on the authenticity data.
