The new atmelimage converts a machine code BLOB to bootable ROM image. Atmel ROM has no sophisticated image format, it only checks the first 7 ARM vectors. The vectors can contain valid B or LDR opcodes, the 6'th vector contains the image size to load. Additionally the PMECC header can be written by the atmelimage target. The parameters must be given via the -n switch as a coma separated list. For example: mkimage -T atmelimage \ -n usePmecc=1,sectorPerPage=4,sectorSize=512,spareSize=64,eccBits=4,eccOffset=36 \ -d spl/u-boot-spl.bin boot.bin A provided image can be checked for correct header setup. It prints out the PMECC header parameters if it has one and the 6'th interrupt vector content. ---8<--- Image Type: ATMEL ROM-Boot Image with PMECC Header PMECC header ==================== eccOffset: 36 sectorSize: 512 eccBitReq: 4 spareSize: 64 nbSectorPerPage: 4 usePmecc: 1 ==================== 6'th vector has 17044 set --->8--- A SPL binary modified with the atmelimage mkimage target was succesfully booted on a sama5d34ek via MMC and NAND.
