Common FLASH Interface

The FLASH devices used in my NIOS II system are not in the pull down menu of supported devices. 

 

The INTEL TE28F320J3A-110 (WORD Mode) is the closest. 

I'm using the TE28F256-xxx (WORD Mode). So the size of the device and the device ID will be different. 

 

I see how I can change the memory size and create a custom device. 

 

What do I need to do to the software to support the CFI. 

 

it looks like the module "altera_avalon_cfi_flash_intel.c" is where the changing needs to be performed. 

 

Has anyone done this? 

Any suggestions? 

 

Thanks In Advance

gmm50, 

 

You should not need to change the software if the device is CFI compliant, the CPU interrogates the device to find out how to program it. There was however a problem with using 16 bit devices in 8 bit mode which is fixed in the 1.01 release.
