About

Instructions to obtain WireGuard details of your NordVPN account. These can be used to setup a WireGuard tunnel on your router to NordVPN.

Source: https://forum.gl-inet.com/t/configure-wireguard-client-to-connect-to-nordvpn-servers/10422/27

Prerequisites

If you have any linux machine, use that or install a vm if you don't have one.

Get their official linux app installed. Make sure you have wireguard installed too. And set the used technology to Nordlynx by running nordvpn set technology nordlynx

Connect aixun 3ta over SWD pins / stlinkv2

This instructions covers how to connect via openocd on linux platform. And assuming you have the STLINKv2 hardware dongle. And that you have wired it up correctly, to the aixun t3a's debugging port.

NOTE:

• Case 1) The swd debugging port should normally only be connected up between your PC and the soldering station. When the target device (the aixun t3a) is fully powered off, and it's mains cable unplugged from the outlet. To avoid having dual powering (both connected), or to avoid grounding / reference issues.
• Case 2) However for live debugging scenarios, or working on firmwares etc. Then you typically would instead disconnect the +3v3 power pin from the SWD port on the STLINKv2. And just tie the GNDs together. To keep the ground reference only. Then have the target DUT (the mcu in the aixun) being powered independantly by itself. Just being aware that this is more risky or delicate situation than when passively powering from the STLINKv2 in the safer
