The CFE of the WRT54G3GV2 expects two firmware images, if one of them produces a CRC error (which is the case after you installed OpenWrt, as there is no second image), it writes one of three consecutive bytes to the flash. (Look for "Image Status : IMG2_BAD" during boot.) After the third boot with a CRC error, it stops and waits for a new firmware image. To prevent this 'noset_try_flag' must be set to 1 on boot. Tested with my own box. Signed-off-by: Niclas Koeser <nks at informatik.uni-kiel.de> git-svn-id: svn://svn.openwrt.org/openwrt/trunk@23007 3c298f89-4303-0410-b956-a3cf2f4a3e73
