Florian, what do you > think? I'm not Florian, but I worked a bit with AR7 as well, and going through the (previously) supported/known devices they topped out at 8 MiB Flash and 32 MiB RAM, which isn't enough to run any reasonably modern OpenWrt even if one would be willing to re-add support for it. So from my perspective I suggest even dropping the AR7 code entirely. I seriously doubt anyone is running a modern kernel on that. Best Regards, Jonas
