Title: IRQ Test
Post by: Pursuit20 on July 31, 2008, 10:29:47 PM

If I uncomment #define IRQ_TEST   in application.c, then this should enable the IRQtest.  With the Eval board, sw2 should be mapped to IRQ11.  In the IRQ_TEST it looks like if i press sw2 on the eval board, it should printout to the terminal "IRQ_11"  I am not seeing this.  Is there something else I am missing that needs to be defined before this test will run.

Thanks,

Hi

Ensure that you also have SUPPORT_EPORT active (in app_hw_m5223x.h) since this will add the driver support - without it fnConfigureInterrupt() will simply return (assumption you are using SP7).

Finally check out SP7 patches - there is a patch for the power up of the edge ports, which you may be missing:

Thanks Mark, I had to add POWER_UP(POWER_EPORT);  in the fnConfigureInterrupt.
