Zynq IRQ-ID

Jump to solution

Hello,

 

you see the Vivado Interrupt configuration window:

 

irq-id.JPG

 

The ID-Column Shows the intervals [91:84] and [68:61].

 

1. If i use only one Interrupt, which ID is used?

 

2. What is the relation between this ID and the device-tree entry?

 

3. What is the relation between this ID and the corresponding "/proc/Interrupts" entry?

 

4. Has UIO any restrictions regarding this ID?

 

5. Is there an UIO based IRQ-Test-Tool available, to see if an Interrupt is working via uio device?

 

6. Is there an very simple complete uio example with Vivado design and working Linux app including bsp?

 

 

Thank you...
