CFI FLASH access from Nios IDE

[Altera_Forum]

Good afternoon. 

 Unfortunatelly, i didn't find the solving of the problem with CFI Flash, so i decided to create a new thread.  I have Cycolne III Dev Kit and flash on the board and want to make access to flash through the CFI.  i have added the CFI Flash and Tri-state Bridge to my project. then made pins in the quartus and try make access to the flash. At last i could get the CFI table from the Nios Command Shell through the nios2-flash-programmer and today i have succefully wrote data to the flash and read it from flash. But i can't do the same in the Nios II IDE. The result of function alt_flash_open_dev(CFI_FLASH_NAME); is zero - so the device doesn't open. The options in system library included all wrivers and the CFI i thnk so too... Are there any ideas why it doesn't work?

I had the same problem 3 weeks ago. 

 The CFI flash is a 16-bit addressable device. I guess you have it wired up as if it was 8-bit addressable. Connect bit 1 of the NIOS address to bit 0 of the CFI device in your Verilog eg flash_padd[22..0] = nios_mod.address_to_the_cfi_flash[23..1]; flash_padd[23] = clr;   hope that helps ... Bruce

Thank you very much. 

I've already successfully done the cfi flash.  You are right, we should connect Nios [1] to pin flash[0]. Besides we shouldn't mark option "reduced device drivers" or the drivers for the Flash won't be included.  Today i tried to start the nios software from the CFI Flash and it works. if anybody have questions about the CFI Flash with Nios I'll try to answer it =)

Unfortunatelly i have another problem: i can't get access to the flash from nios ide in the example of simple socket server (SSS), but i can see the cfi table from command shell of nios ide. I didn't check the small с library or reduced drivers in system library. 

But when i start the example of hello world - i can access flash from nios ide but a have the same settings of system library as for the SSS =(  Are there any ideas about this case?

Hello to everybody. 

 I made my flash workable, but now I have a question.  I have a special board with Cyclone III, not dev kit.  There is no Max II. So I want to program my flash with Nios software to store there my cpu code. How can i programm it? There is a parallel flash loader, but it can load only pof files (sof i can convert to pof). And what about the *.flash type? Maybe there is a converter such as sof2flash, but flash2sof?
