From d6cd09a0d0c80f4b7a726cb85c82cfe631e6b88e Mon Sep 17 00:00:00 2001 From: Sven Eckelmann Date: Thu, 19 May 2016 20:21:01 +0200 Subject: [PATCH] scripts/om-fwupgradecfg-gen.sh: Fix u-boot image md5sum check The u-boot on Open Mesh devices checks the whole transfered image against a md5sum. This is stored inside the option filemd5sum inside the fwupgrade.cfg. The bootloader will not check it when this setting is missing and could therefore write invalid images to the flash.
