Hello I am a student researching router security in Iceland. My group has been tasked with emulating common routers for dynamic analysis. We have obtained a firmware image for a tp-link ex820v that seems to be running OpenWRT with this kernel: ARM64 OpenWrt Linux-5.4.211 I could use some help compi…
