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.

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.
