mmccard_boot_blocking
Overview
The MMCCARD Boot project is a demonstration program that uses the SDK software.The purpose of this example is to show how to use MMCCARD driver andshow how to use interrupt/polling based transfer API in SDK software driver to access MMC card boot partition and boot from mmc boot partition.This example include two sub-examples which is controlled by macro MMC_BOOT_STORE, if the value is true then the default image and mmc boot configurations will be loaded to mmc device, the configurations can be modified in the source file, such the boot bus width and boot timing and so on.If the value is false, re-compile the project and reset the mmc device power, example will load image from the mmc device, in this example, image header is loaded first then load the left image.Note: Make sure store the image and configurations to mmc first.And only USDHC support this example now.User can use MMC plus card or emmc(on board IC, but not recommand use emmc socket,due to high speed timing restriction)
