Hello,
I need to connect a device to uart. I saw in documents that the only uart is ttyS2.
ttyS2 is connected to the debug console of the ROCK64.
How can I free ttyS2 for my purposes?
The image I used is "stretch-minimal-rock64-0.8.3-1141-arm64.img".
I opened "/boot/extlinux/extlinux.conf" but there isn't reference to tty console to disable.
