free UART - drekrob - 12-06-2017
Did someone manage to disable Serial Console to free up the UART for other another purpose?

I think I just did, here are the steps:
sudo apt-get install device-tree-compiler
dtc -I dtb -O dts /boot/efi/dtb > tmp.dts
// open tmp.dts with your text editor find section 'serial@ff130000' and set status from 'disabled' to 'okay'
// then scroll down to find the 'fiq-debugger' section, set this status to 'disabled', save it
dtc -I dts -O dtb tmp.dts > tmp.dtb
sudo cp tmp.dtb /boot/efi/dtb
after a reboot /dev/ttyS2 should be ready to use, good luck

Switching the UART in the Linux dts should work fine, but I think there are other UARTs in the pin multiplex?
