Hello Jason, yes this works indeed thank you! This means however that NEON SIMD instructions are not used, right ? The datasheet of the board mentions that it includes the NEON SIMD coprocessor : https://dn.odroid.com/S805/Datasheet/S805_Datasheet%20V0.8%2020150126.pdf And CONFIG_NEON=y is activated in the kernel. Forgive me, I don't know much about what it means for the wireguard module not using the neon simd instructions.
