WebJan 22, 2024 · The SPI flash can be used to store a bootable firmware on the low cost development boards, which do not offer any other kind of non-removable storage (NAND or eMMC). The minimum amount of the required storage would be 1 MiB (8 Mbit) to fit a user friendly bootloader with some advanced features. WebUse the MTD interface provided for SPI flash on the EVM to validate the SPI driver interface. The below step copies 8KiB from /dev/mtd2 partition (u-boot env) to /dev/mtd4 partition and reads the 8KiB image from /dev/mtd4 to a file and checks the md5sum. The md5sum of test.img and test1.img should be same.
