hi giulio, still no response?

Nope. My understanding is that you need the GUI but the CTAG image comes without a GUI. So you installed a more recent version which has a 4.14 kernel and for which the CTAG overlay doesn't load, is this correct?

In that case, I guess you have two options that do not involve fixing the device tree overlay:

  • install an older version of the image for which the overlay still works
  • use update_kernel.sh to install a different (older, possibly 4.4) kernel. This should be (but I may well be wrong) in /opt/tools/update_kernel.sh on a beagleboard image.

Hi Giuliomoro, I've returned to this issue with Kernel, ALSA, and CTAG. I've already tried to downgrade the kernel version to 4.4.155-ti-r155.
Then, I evaluate this: dmesg | tail -n 20 and that: bash -x ./load-ctag-beast-16ch-drivers.sh
and still, I can't assign the CTAG as a soundcard.
Do you have any suggestion on how to keep the GUI in Debian and to run up the CTAG on it?
