Essentially, it said all you need to do is add the wndr3800ch to the Makefile in 2 places. I've done a bit of compiling in my day so I gave it a shot.
I did a git clone
https://github.com/dtaht/cerowrt-3.10.git to get the lastest. Edited the Makefiles as described and followed the instructions per the README. All compiled beautifully. I used the default .config as didn't see any addition things in make menuconfig that'd be needed.
I found the squashfs was only 2.9M but did create the correct file for the device.
-rw-r--r-- 1 plewis plewis 2.9M Jul 31 18:23 openwrt-ar71xx-generic-wndr3800ch-squashfs-factory.img
I was able to successfully flash this img file and get openwrt installed. I know there are a ton of ipk packages missing as to even start, I had to telnet in. I connected and added luci to get the webUI up. Its missing most of the cerowrt packages. The first package I tried to add was the sqm packages. Not there.
I know I'm missing a bunch.
To start, I'm just looking for a good .config that includes all the cerowrt base packages. Any other instructions would be a bonus. I could be on the wrong course here and its really a feeds.conf issue and I need to add in additional feeds.
The latest build instructions are for the 3.3 kernel and not 3.10.
Please be kind and let me know if I should move this to cerowrt-users. I figured compiling was a little higher level than the users mailing list.
Cheers to this project,
Pete
