Hello, I need use UART 7 or 6 to communicate with other component.
I'm using TI-RTOS 2.14.04.31, on a TIVA TM4C1294NCPDT.
I based my project on 'uartecho_EK_TM4C1294XL_TI_TivaTM4C1294NCPDT' example. I made the following changes:
On EK_TM4C1294XL.c

Bu don't work, here is the error:
What am I forgetting?
