I'm trying to make an interrupt handler by UART. Here is a link to the code I use:
https://www.programmersought.com/article/9640953879/However, when initializing the UART, the controller freezes on registering the interrupt handler function:
UARTIntRegister(UART0_BASE, vUART0_IntHandler);
(under the debugger, I checked the input to this function, the filling of the interrupt vector, but when exiting this function, the debugger does not go further. I even made a semaphore of LEDs to make sure that after this function, the controller stops further code execution) Moreover, the function vUART0_IntHandler - can be either filled or completely empty.
I feel like I missed some detail.
What is missing in the code?
Who knows - please help!
