Quartus 16 QSYS PIO issue

Honored Contributor II

Hi all,  

I've a problem to add 32-bit PIOs in the NIOS. I had an old Quartus 13 project and I migrated in Quartus 16. I added new 32-bit PIOs identical to the old ones. When I tried to set them into NIOS software using "IOWR_ALTERA_AVALON_PIO_SET_BITS(PIO_BASE, 0x1)", I wasn't able. Obviously with the same instruction, I could to set the old PIOs, the ones created in the Quartus 13 version.

I'm having a simmilar issue, none of my peripherals are working in quartus 16 and they were in 15.1, I'm just rebuilding my project from scratch.
