free UART

[drekrob]

Did someone manage to disable Serial Console to free up the UART for other another purpose?

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?
