Hello all. I am trying to learn as much as i can here so please forgive my noobish questions. I am trying to compile openwrt for the RPI2 (BRCM2709). It has a stable build for 15.05, however, it does not have the latest kernel needed for multiwan.

There i have compiled my own from source using:
http://dab-embedded.com/en/blogs/openwr … erry-pi-2/

However when i change anything (like trying to include luci) the build always fails. In my desperation i pulled the config.diff file from https://downloads.openwrt.org/chaos_cal … 8/bcm2709/ and ran a make defconfig This is still resulting in a failure to build the packages.

The only success i have had has been a BAREBONES build that includes nothing but the CLI and the target system. Which wouldnt be a problem if i could add the packages with okpg however that does not work either due to bad signatures...?

Any advice is appreciated!!
