For Microblaze and Interrupt Controller, add: Sep 1, 2020 · Hi, I made it work in normal mode, concat receiving 2 sources (timer and gpio), and going into the interrupt controller. When generate Microblaze and interrupt controller together, the "Enable Fast Interrupt Logic" will be clicked. The ARM cores are really fast but that doesn't mean that a MicroBlaze couldn't have a similar problem. But then 0x1d30 jumps to 0x1c. When an interrupt occurs, the following actions happen. I reach out to a co-worker about interrupts and the zynq processor and interrupts should be enabled in the zynq config wizard, creating the IRQ_F2P port. How do I get my exception handler to get called? The interrupt handler is never triggered. Here below my full implemented code: I created a custom IP and send a interrupt to microblaze by directly connecting the out pin of IP to interrupt pin of microblaze. Here the code but do not work. Apr 12, 2018 · FIRST WORKING TEST WITH TX INTERRUPT ON UARTLITE (VIVADO 2016. After a while, ping response is “Destination Host Unreachable”.
