Giuseppe

Interesting.
I am not sure how it is handled in Poky 1.4, but on a vanilla Linux distribution you should have directories in /sys/module/ for the kernel modules which need them for their configuration.
kgdboc being such a module, it should have its own directory there.

Could you do:

root at imx6qsabrelite:~# ls -l /sys/module/kgdboc

And paste the output here ?

Cheers.
