Concerto C28x External Interrupt

HRi

Hi,

I'm trying to run the Concerto C28x external interrupt example with no success as I'm not getting interrupts, I did the connection necessary as defined in the external_interrupt_c28.c file header -

"Connect a jumper across rows A and B at position 2 and 19 of the ABC header

//! to route PE6_GPIO30 and PE7_GPIO31 to the pins at the base.The user must
// then
//! externally connect these pins(PE6_GPIO30 to PA0_GPIO0 and PE7_GPIO31 to
//! PA1_GPIO1) at the base board for the program to work properly"

I also tried to allocate GPIOA for the controller in the M3 side, what could be the issue?

Thanks,

HR,

What program are you loading and running on the M3? Can you try just toggling the IO from the C28x which are you attempting to use to generate the XINT to make sure it's ownership is allocated properly and the docking station setup is correct?

Kris,

We solved the issue by setting on the M3 the GPIo to the control and enabling the GPIO,
