Hi folks, I got problem to use Razberry Z-Wave board on GPIO. There is no /dev/ttyAMA0 in the Debian distro for Rock Pi 4. I tried ttyS0 (that’s the case for Raspberry Pi 3) apparently not it either.
Anyone knows which one the GPIO HAT is supposed to use? Please help, thanks!
EDIT: maybe the question should be: in the Debian distro for Rock Pi 4, how to make pin 8/10 (GPIO pin 14/15) available to HATs on GPIO? On Armbian some people tweaked /boot/script.fex to enable uart0 (the 2 pins mentioned above) to make ttyS3 working, what about Rock Pi 4 Debian? I have no clue where to look. This is supposed to be a basic feature since many HATs are using it.
Seems I need some kind of device tree editor to use it? Gee…
uart0 (serial@ff180000) seems to be the bluetooth which is enabled, uart1 (serial@ff190000) is disabled, is it GPIO 14/15 (pin 8/10)? Please anyone?
