I soldered my rp 2040. Once I turn it on it boots to the Nintendo system. My c point( pictures below) won't connect with the tin.

clean it with some isopropyl alcohol and a toothbrush, then try to solder it again. and pick a better thread name next time

Probably fine. Get a better photo, can't really see the point in the one you provided. Need better lighting

If it still boots to ofw then your trace's fine. Also what flux did you use?

The flux worked for everything except this one contact. We tried it withe better tin and more flux. It still won't connect.

My grandpa has the idea of connecting a wire to both contacts. Will this work better?
