From 7b1a411743db47648b2955c414a71836823acfd9 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Andreas=20Bie=C3=9Fmann?= Date: Mon, 19 May 2014 14:23:39 +0200 Subject: mkimage: add atmelimage MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit 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.
