UART-0 interrupt and freertos

fayyazrafiq

Dear All,

Has anybody configure interrupts  for zynq in freertos environment. I tried UART-0 interrupt but my interrupt never hits. Could anybody share some sample code for any interrupt in freertos environment.
Any help is highly appreciated.

Regards
M. Fayyaz

    Did you get this to work? I am trying to configure a interrupt but does not seem to work

    I was able to implement the FPGA interrupt ( 91) which is a SPI and i suppose you could do the same for UART as well.

    I did the following

    The interrupt controller is already initialized for the TICK interrupt. So i used

    prvGetInterruptControllerInstance();

    to get a instance of the same in my main function. Then I connected my SPI interrupt with the controller using

    XScuGic_Connect

    I enabled the interrupt using

    XScuGic_Enable(InterruptController, 91);

    After that I set the Target CPU ( in my case CPU1) using

    CpuID = XSCUGIC_SPI_CPU1_MASK;
    CpuID |= CpuID << 8;
    CpuID |= CpuID << 16;

    XScuGic_DistWriteReg(InterruptController,XSCUGIC_SPI_TARGET_OFFSET_CALC(91),CpuID);

    Then it works. I hope you can do the same for UART since it is also a SPI
