Accessing Fabric PIO from the VxWorks on Arria10.

Hi Sukesh,

This is duplicated case. This same query has been answered on the IPS case and email id.

Regarding the example for PIO core with HWLIB. There is some reference given with the NIOS II and PIO in the below document.

https://www.intel.com/programmable/technical-pdfs/683525.pdf

It seems we don’t have driver for FPGA IP’s with the HPS with the Baremetal/HWLIB.

You can find the available and latest driver list with the Baremetal/HWLIB on https://github.com/altera-opensource/intel-socfpga-hwlib/tree/master/examples/A10

But if you are going to use the linux, then yes we do have PIO driver in linux and same we have showed you using the LED/Button example from the GSRD/GHRD.

With that, I now transition this thread to community support.

Thank you.

Best regards,

Tiwari
