Hi @Jesse_CP,

Are you using an interrupt controller to drive your interrupt? In this version of PYNQ you cannot connect the interrupts directly to the IRQ pin on the PS.

See discussion here

> Earlier versions of PYNQ required an interrupt controller, in the latest version a single interrupt can be connected directly to the IRQ pin. More than one interrupt, requires an interrupt controller.
