Bootload InfoPlugin > Storage
Info about what firmware update image should be bootloaded next.
This plugin provides the bootloader with support for storing multiple images, and attempting to bootload a prioritized list of them. The Bootload Info struct is placed at a known location in storage, and points to a list of images to attempt to bootload.
While the Bootload Info list of images to attempt to bootload has a compile-time configurable size, the bootloader is capable of handling lists of images with different sizes, e.g. if a bootloader upgrade changes the slot layout, or if a storage device that was initialized on a different device is used.
If only one storage slot is available, the functions available in this API will do nothing, and return applicable error codes (BOOTLOADER_OK for storage_getBootloadList and storage_setBootloadList, and BOOTLOADER_ERROR_BOOTLOAD_LIST_FULL for storage_appendBootloadList).
