🌷 Blinking through Linux 🌌
Vivado part:
- Check for various warnings under ‘Platform Setup’
- With respect to PL 2 PS interrupts, add an
AXI Interrupt Controller between the GPIO_CLK interrupt and the Zynq_IRQ:
- (Also set the interrupt controller’s output, to “single”):
- (Adding a NOT gate clarifies the button’s active state).

This should be enough for the PL(LEDs) to blink.
