Abstract: A method of improving synchronization over a secure digital (SD) bus between an SD host and an SD client device is described. The method includes writing to a client event register to interrupt the SD host for an SD extended command. The method also includes triggering the SD host to issue the SD extended command to the SD client device over the SD bus in response to the SD client device writing to the client event register.

Abstract: Systems and methods are disclosed for providing stack overflow protection on a system on chip via a hardware write-once register. An exemplary embodiment of an system on chip comprises a hardware write-once register, a boot processor, and one or more processor subsystems. The boot processor is configured to execute a read only memory (ROM) image which initializes the hardware write-once register with a first numeric value in response to the system on chip being powered on. The one or more processor subsystems have an associated software image configured to use the first numeric value in the hardware write-once register as a stack canary value to combat stack overflow attacks.

Abstract: Various aspects include methods for implementing a firmware patch infrastructure. Various aspects may include identifying a patchable object from a firmware source code image based on a symbol in the patchable object's name, generating a patchable firmware source code file by injecting a first call to the patchable object configured to call to an indirection table and a second call to the patchable object configure to execute the patchable object, building a patchable firmware source code image from a plurality of patchable firmware source code files including the patchable firmware source code file having the first call to the patchable object and the second call to the patchable object, and creating the indirection table including an entry for the first call from the patchable firmware source code image having an indication to implement the second call in the patchable firmware source code image.

Abstract: Methods, systems and devices are provided for revising a data image of a read-write memory device. The method includes accessing an initial data image from an initial virtual block corresponding to an actual block of a series of actual blocks of the read-write memory device. The initial data image includes an initial boot loader. Also, a backup data image is stored in a remote virtual block spaced away and following in the series of actual blocks from the initial virtual block. The backup data image includes a backup boot loader. Additionally, the initial data image is erased from the initial virtual block and a replacement data image is stored in the initial virtual block. The initial virtual block may include more than one virtual block spaced away and proceeding in the series of actual blocks from the remote virtual block.

Abstract: Methods, systems and devices are provided for configuring a read-write memory device with a data image. The method includes determining a data image distribution based on a virtual block size of a series of virtual blocks designated for the read-write memory device. The data image is divided into one or more data image portions, wherein a virtual boundary code is appended to at least one of the data image portions. The data image portions are stored in respective virtual blocks of the series of virtual blocks, skipping over any bad block within the read-write memory device, even between the virtual blocks.
