EPCS access using interrupt in Nios-II

Hi,

    I have custom board with Cyclone-IV device EP4CE55F23I8L. I used Quartus Prime 16.1 standard edition. 

    Presently I have NIOS-II program for access non-volatile EPCS data using NIOS-II EPCS Controller core HAL Drivers by using polling method. But now I have another program where this polling method disturbs other NIOS-II Functionality. Therefore I want to access EPCS Controller core by interrupt method.

   Please share some examples of interrupt method for accessing EPCS Controller core or some documents which can guide the same.

   Thanks

Regards,

Nandish Jasani.

Hi @NJasa,

Good day, and hope you are doing well, regarding the question that you have, perhaps maybe you can take a look at the ventored interrupt controller to see fi that fits the design that you are trying out.

You can view more details on the controller here:

https://www.intel.com/content/dam/www/programmable/us/en/pdfs/literature/hb/nios2/n2cpu_nii53002.pdf (under the section 'Vectored Interrupt Controller Core')

And for here are also some sample reference design:

Hope that helps.
