A5E: tun support

I want to have the A5E as the router between my network and the outside world. That mostly works, except that I’m running into trouble getting the VPN up and running. As far as I can see the kernel was compiled without “tun” support, not even as a module.

I’m using the a527_cubie_a5e_bullseye_beta_20250303.zip image. (The armbian_community images looked more promising, but don’t work with the second ethernet port).

So now I have to recompile the kernel. How would this work?

As far as I can see, I’d have to download the tina 5.0 SDK, but the link goes to a place where i have to wait for six hours every several Gb. Is that really necessary?

When I would get a kernel, where does it need to go ? I can’t find a linux-kernel package on my debian install. I cant find the kernel in /boot. I tried mounting the other partitions and only p1 mounts, and contains a bunch of BMP images, but no kernels. The other two partitions don’t mount . So if I were to get a kernel compiled, where does it need to go?
