From 7d81c1b6ccb39833ab3ff5f2f890bc03e22c9d84 Mon Sep 17 00:00:00 2001 From: Florian Fainelli Date: Sat, 5 Jul 2008 13:38:19 +0000 Subject: [PATCH] If the *.img file is larger than 0x1e8000 loading it with flash -s 0x100000 -d 0xffe08000 -l on the bootloader prompt will destroy the bootloader and brick the device. The attached patch tries to implement a size check and renames the image into *.img.too_big. It applies to svn r11401.
