Hi
I have run into a few problems with building 7.09. Thought I would summarize them here.
I am building for a WL500Gp with Atheros minipci card.
I have
* svn co https://svn.openwrt.org/openwrt/tags/kamikaze_7.09 7.09
* applied by boot usb patch (see below)
* make package/symlinks
* make menuconfig
** changed the static ip information
** built into the image these modules
*** kmod-fs-ext2
*** kmod-fs-ext3
*** fdisk
*** e2fsprogs
*** libuuid
*** kmod-usb2
*** kmod-usb-core
*** kmod-usb-storage
*** kmod-scsi-core
* make
* run mtd -e linux write openwrt-brcm47xx-2.6-squashfs.trx linux on the router
* waited for the system to settle (firstboot)
* reboot
* fdisk /dev/sda - create 1 Big partition - ext2
* mount /dev/sda1 /mnt
* mount -o bind / /tmp/root
* cp /tmp/root/* /mnt -a
* umount /mnt
* reboot
This failed. On my working image (7.07) where I can boot from usb stick, I did not include the extra modules in the image, but ipkg installed them on the first reboot.
Attempting to debug this (7.09) I replaced perinit back to original and updated /sbin/init (see below), to try and capture some output and error messages
whilst doing this I became aware of a lot of segfaults that I was getting, at random times, different applications would fail. trying ps would fail, but if I trued /bin/ps it would work. saying that if I tried /bin/busybox ps it would fail. But no constantly
also noticed that my root partition was actually a jffs not squish - i think this is just me not understanding the fs status right now
I can see that all the modules are loaded, hotplug2 is loaded and running and prepped for usb, i can see the device I can run mount, but for some reason I can run mount /dev/sda1 /mnt. I have ext2 and ext3 loaded. I have attached my last init.text as the bottom
can find any pointers on where to go from here.
There has been some suggestions to go back to 2.4, but I want the 2.6 kernel for some of the iptables & ipv6 stuff.
I will try now going back to my 7.07 build, with out the extra packages, just to prove to my self that it is possible and then work forward from there!
Boot USB patch - worked out form other post

and I don't have console access - I tried the fail safe as well, setting up an ip and starting up telnetd but it did not help .............
