dm365 GPIO interrupts

Craig Smith
Intellectual 810 points

Hello, I would just like to confirm that interrupts are only available for GPIOs 0-15 on the dm365. Is this true?

It appears on the EVM that most of those 16 GPIOs are used by UART and Ethernet (except for GPIO 0).

Is there another way to configure interrupts for GPIOs >= 16?

 

Thanks,

-Craig

    This is the case on the DM365, the GPIO module can only generate interrupts from GPIO [15:0], and as you have found this means that if you are using the EMAC all you really have available is GPIO0.

    Unfortunately there is not internally, you would have to multiplex the interrupt signals into the GPIO interrupt pin(s) you have available through external logic, and delineate between the source in software.
