Hello!
for the last few months I've been working on a custom PCB using the RP2350B (I named it the PIcroscope). The end goal is to stream a camera feed from an OV5640 to a display via HDMI.
2 days ago I got the PBC's from JLC, but when iI tried to flash a demo code onto the Board, the Mass Storage won't show up. Yesterday I tried debugging possible errors and I may have found sth. The Board is able to boot into MSD-mode when i supply an external Sinuns with 3.3V peak and a freq of 12MHz.
Below I have the link to the repo where the KiCad files are located. It would be a huge help for me if someone could take a look at these as I'm quite sure this is a design error cause both of my assembled board aren't working.

Best Wishes and Thanks,
Nico
