From 2911bd1858d11308164b0b33de4ea0e8994d3edf Mon Sep 17 00:00:00 2001 From: Przemyslaw Marczak Date: Fri, 22 May 2015 18:14:28 +0200 Subject: samsung: common: add example boot scripts This commit adds example scripts of boot.scr: - bootzimg.cmd - check if dtb exists and boot zImage - autoboot.cmd - check which image exists: Image.itb, zImage or uImage and optionally load fdt file for u/zImage The blank spaces are added to improve readability and can be removed before use mkimage. Required U-Boot environment variables: $boardname, $fdtfile, $console, $mmcbootdev, $mmcbootpart, $mmcrootdev, $mmcrootpart, $rootfstype. Making boot.scr from file.cmd: mkimage -C none -A arm -T script -d file.cmd boot.scr The Odroid XU3 default environment is ready for those boot scripts and the right script can be loaded by DFU.
