How would I use the interceptor board with OpenWrt? I flashed the latest img to a usb stick. Resized the second partition to fill the entire drive. Then changed the cmdline.txt to the following:
console=serial0,115200 console=tty1 root=PARTUUID=5452574f-02 rootfstype=squashfs,ext4 rootwait
It seems to start booting ok but seems to get stuck. Is it because the drivers aren't in the kernel they are using? Do I need to compile my own image and patch it? Would I need to do anything with the swconfig?
I am sorry you are having difficulties with WRT. Unfortunately, we do not have any systems running WRT, so we cannot offer much in the way of assistance. I recommend checking out WRT related forums for assistance.
