Hi All, 

 

Can I use any CFI Flash device with NIOSII? In this case, where does the SOPC builder know where to get the flash driver from? 

 

Appreciate all the help.

Isn't the point that if the flash is CFI-compliant it should, in theory, just work? You do need to specify the signal timings for your device. There is a list of devices verified as compatible in the NIOS II Flash Programmer User Guide. 

 

Has anyone had trouble getting a particular CFI-compliant flash working?

the devices need to comply with either AMD's or Intels CFI spec.

Mostly all CFI Compliant Flash memories should work.

When I add a CFI in the " .ptf " , I find I can select 8/16/32bits data width with the flash. 

Is there any 32bits data width flash on sale? Most of the flash data width is 8/16bits width, what does the 32bits mean?

32Bits is done with 2 16Bit devices or 4 8bits devices. 

This CFI component is available in the SOPC_BUILDER for years and has been widely used for many FLASH founder. If you raise any issue, please flag mysupport.altera.com.
