Configured UART RX interrupt on K2L arm core. IPR register (interrupt pending register) is set on UART Rx interrupt, but IAR register (interrupt Active Register ) is not set, i.e the core has not received the interrupt.
Crossbar registers are not pat of ARM core in K2L.
Portion of code is here with:
int main(void)
{
int readdata =0;
platform_uart_init();
UartINTCConfigure();
IntEnableSecureMode(277);
UartWriteData(0x32);
while(1);
}
static void UartINTCConfigure(void)
{
Intc_IntDisable();
/* Initializing the Interrupt Controller. */
Intc_Init();
/* Enable the interrupt */
Intc_IntEnable(0);
/* Registering the Interrupt Service Routine(ISR). */
Intc_IntRegister(277, (IntrFuncPtr) UARTIsr, NULL);
/* Setting the priority for the UART interrupt in INTC. */
Intc_IntPrioritySet(277, 2, 0);
Intc_SystemEnable(277);
}
