I have a nios system which interfaces an ADC through Qsys.I have about 20 no:s of PIO's configured for this.
16 PIOs for the databus from ADC,one for Chip select,one for adc reset,two for SOC of adc.when i create all the pio's its always showing the problem in nios that its not able to download the .elf file.If i reduce the no: of PIO's by 19,then i can download the program to nios.What can be the reason for this?

Which PIO are you removing? Does the error go away if you remove anyone of the PIO's, or is it just specific to a certain one? If the problem is fixed by removing a PIO from lets say your adc reset, then you can point back to that as your issue.
Can you post the error message(s) you are receiving?
