UEXT1 is sideways, is that 90ยบ clockwise or counterclockwise from the photo of the board?
There are markings on the board near the UEXT connector, at the cut side - these markings show "1" as pin #1 of the connector and "9" as pin #9 of the connector. Furthermore, the plastic connector of the UEXT itself has a small arrow marking indicating the first pin. These would help you identify the orientation.
ah, I see it, thanks!
