Can I/What can I do…?

dtoverlay=dwc-otg no longer working on the RevPi Core S, what can I do?

The dwc_otgdoes not work there because the fiqsupport is missing.

On a CM4S-based device, the XHCI controller mode (USB 2.0) can be used with otg_mode=1 in /boot/config.txt.
dwc_otg, can only be used on older CM/CM3/CM3+-based devices.

How can I find which application consumes hidden RAM?
