Using Flash memory on Nios Dev Kit

Hi  

 

I have connected the AMD AM29LV065D flash memory device on my Nios development board to use it as program memory.  

 

The build in SOPC and the analysis and synthesis in Quartus runs ok. But when running the fitter I get this error msg: 

 

Error: Can't place node ~DATA0~ in location H12 because location already occupied by node tsb_data[0] 

 

where "tsb_data[0]" is my user defined output connected to the tri-state shared bus "data[0]" and assigned to pin H12. When removing this assignment the fitter completes without any errors, so all the other assignments (to data[1]…..) are accepted. 

 

By the way: When using NiosII evaluation kit I have a timelimit on the NiosII core. Is it still possible to load my sof into flash or do I have to program the FPGA from Quartus? 

 

Thanks
