Hi,
I've been using the /dev/ttyAML1 UART port on my Odroid N2+ at the GPIO pins 8 and 10 with buster. With the update to bullseye, the /dev/ttyAML1 device disappeared. Also now in bookworm it is no longer present.
Now I happen to need the UART at GPIO 8 and 10 again and did some more persistent research and came across this post over in the DietPI forum. It provided an alternative meson-g12b-odroid-n2-plus.dtb which I installed in my system. Since then my /dev/ttyAML1 device is back and I can use the UART at GPIO 8 and 10 as I wished.
However, I am a bit nervous, since I just installed some binary dtb file to my system at a path which is owned by the linux-dtb-current-meson64 package. So it is endangered by a system update.
Is there an "official" way to get back my /dev/AML1 UART device which is sustainable?
Thank you very much
