Thanks again for all of your suggestion. I'm actually gonna go and buy a multimeter to make sure I'm getting connectivity on my solder points. I will let everyone know of the outcome.
Also, does it matter which D0 I'm using on the Xenium chip? The reason why I'm asking is because the contact on top of the chip (whatever side the logo is on) came off, so I had to resort to the other D0 point.
Hopefully I'm making sense here.
