please select 'compile the kernel with symbol table information' under 'global build options', then recompile, reflash and show the new crash log

comment:2 Changed 9 years ago by drexel@…

I am experiencing the same bug on the 8.09 release. It doesn't matter if I build from source or use the provided binary from the webpage.

I checked out the source using the command:

svn co svn://svn.openwrt.org/openwrt/branches/8.09/
cd 8.09
make menuconfig

However, I do not see any section named 'global build options', nor am I able to find where to select 'compile the kernel with symbol table information' anywhere.

I get the same menu system when I download the source tarball and run 'make menuconfig' in that dir as well.

Any ideas on where this option might be?

Got the below error(s) when booting newest openwrt-rb532-jffs2-128k.bin . Version from January boots with no issues though...

This has been fixed in the svn release of 8.09. This is how I got it working:

Check out the 8.09 sources from svn and build your own image. I have no idea how often they rebuild the packages on the download site.

svn co svn://svn.openwrt.org/openwrt/branches/8.09/
cd 8.09
svn up                      # i had to do this to get the most recent patches
./scripts/feeds update      # to update all the packages
./scripts/feeds install -a  # to make all the packages show up in menuconfig
make menuconfig             # select platform and options
make world
sudo dd if=bin/openwrt-rb532-jffs2-128k.bin of=/dev/sdXX

I also found that building from the unpatched (non-svn) release tarball worked if I disabled the ability of 'ifconfig' to display statistics. It's one of the options under the BusyBox 'network' config. This removes the ability to do ifconfig -a or ifconfig eth0, but it's better than crashing.
