I am trying to access the serial console in my router TP Link Archer C20 V1. I think I have set up everything as required, yet I fail to see the console screen running when I start the router. I recently bricked (or so I think) while trying to install OpenWRT. Could someone please guide me on how to do this the right way? I want to update the wiki page (https://openwrt.org/toh/tp-link/tp-link_archer_c20_v1) with more images and steps after successful installation.
