How to install Kernel table of isr.c Example?

[norbertoj]

I am working in the example project of ISR. I am using TWRK60N512. I compiled isr library and the project; but, when I tried to debug or run isr.c, Terminal received the next:

====================== ISR Example =======================

Press the SW1 to blink LED1, press it again to turn it off

Install interrupt handler to hardware vector table failed.

So, I can consider that there is a problem in the code in this part:

    /* Install the interrupt directly to the vector table in the processor. */

    if(! _int_install_kernel_isr(lwgpio_int_get_vector(btn_ptr), btn_kernel_isr))

    {

        printf("Install interrupt handler to hardware vector table failed.\n");

        _task_block();

    }

But I don't know where this example is wrong.

Anybody can help me?

I am confused because I have never change anything of example code. I am ataching the example of MQX 4.2

Hi

I did a quick check with this demo C:\Freescale\Freescale_MQX_4_2\mqx\examples\isr\build\cw10gcc\isr_twrk60n512.  My result is OK.

I set the MQX_ROM_VECTORS macro to zero in the user_config.h file prior to compilation of MQX kernel libraries and the example itself.

I suggest you trace the function _int_install_kernel_isr , and check the error code for further investigation.
