Hello,

 

I wanted to test wireguard with my cubox i4, but I'm not able to load the module.

 

I tried to search the net for this error, but fond nothing useful.

 

Maybe someone has an idea.

 

Thank you

Michael

Are you able to build a kernel on your own? Build a fresh kernel with parameter WIREGUARD="yes" ... it is known to work on our most used Allwinner kernel.

Hi, I tried it with the new " 5.1.16-cubox #5.90 SMP Sun Jul 7 11:37:47 CEST 2019 armv7l GNU/Linux" kernel, but still the same problem.

 

I also tried to build the module with dkms with the wireguard package from debian sid, but the build fails. Here is the logfile of the build.

What about modprobe wireguard since module should be build into the kernel?

DKMS could need some fine tuning ...

Same problem on hummingboard i2ex (running -cubox kernel) both on kernel 4.14 and 5.1. Built-in module doesn't work - throws this exec format error.

 

DKMS on 4.14 says that it built identical module to one shipped with kernel. I removed wireguard from /lib/modules, run depmod and installed wireguard -> no luck.

On 5.1 fails to build scripts/ in headers (won't build at all), like headers are broken. Self-built module from linux-source-next-cubox after make oldconfig fails in the same way (Exec format error).

 

Found older versions of wireguard sources -> wireguard-dkms_0.0.20190406-1_all.deb and wireguard-dkms_0.0.20190227-1_all.deb,  nothing changed.

 

Trying to load module pops "wireguard: unknown relocation: 102" in dmesg.

We need to fix kernel recompilation first. I tried to build 5.2.y and 5.3.y yesterday, but could not boot the board ... will debug perhaps later today or next week. Then Wireguard.

WG works, thanks!

Yesterday I noticed that at least on 4.14 GPIOs doesn't work for me (exports, sets direction without errors, but real output on pins won't change) , but that's story for another thread. I used oldstable (with kernel 3.14.79-cubox) until yesterday so I just found that - need to investigate first.
