Is it possible to use both the UEXT and debug UART for external devices, i.e. disable the terminal on the debug UART to free it up for other things?
Hi,
yes, its possible.
Check out the kernel console command line parameter:
https://www.kernel.org/doc/Documentation/serial-console.txt
Additionally Christians blog post describes how he changed the console from debug UART to Application UART. The post contains some helpful information:
