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?

Does any other application run in the background, and which is not getting captured from TOP command, How can I find which application consumes these hidden RAM?

I would like to access the built-in RS485 interface of the RevPi Connect - which interface is the right one?

The correct interface is "/dev/ttyUSB0"
The "/dev/ttyAMA0" transmits the PiBridge data

I want to work with a touchscreen, but the pre-installed epiphany browser does not work accurately, what can I do?

Install and use Google Chrome.

In general, there are different possibilities to output the messages on serial interfaces during boot:

Yes, create a minimal image with the Image Bakery.

Would it be possible to change the static values of PiCtory dynamically?

Yes, but only with the Image Bakery.a workaround.

Please keep in mind that the driver has to be restarted.

Is there another way to rest the driver programmatically, i.e., via C language?

Yes, with piControlReset();

I need to find a number inside the KUNBUS with buster distro that is not copied copying the system image.

You can use the unique serial number from the Revolution Pi for this. This can be read out with piSerial. This number is unique because it is read from the crypto chip as well as from the TMP module.

Code Block
$ piSerial -s

Is a Rust library planned, like the library for Python?

No, this is not planned for the near future.

Others Questions…?

Now and then, the service crashes with the error "Main process exited, code=killed, status=11/SEGV". The crash appears to be random and is not related to any event happening in the application, nor the controller.
