Hello,

You did not configure the control register of the UART to specify which interrupt you want to activate (cf Embedded Peripherals IP User Guide pp 7-11 to 7-15). So it is normal that the ISR is never executed.

Regarding the function alt_irq_enable, you don't need it, by default the interrupts are active. You need this function only if you want to deativate an interrupt and reactivate it later.
