Hello,
I have problem using Flash Programmer. I am trying to write something to flash of my custom board, but doesn't seem to work.. Below message appears: ------------------------------------------ [SOPC Builder]$ nios2-flash-programmer --input=xxx_fpga.flash --sof=d:/doors_h ome/xxx/xxx_board/system/xxx_board.sof --base=0x00800000 WARNING: Default charset MS932 not supported, using ISO-8859-1 instead Oct 6, 2005 8:32:57 PM - (??) nios2-flash-programmer: Launching Quartus Program er to download: d:/doors_home/xxx/xxx_board/system/xxx_board.sof Oct 6, 2005 8:33:01 PM - (???) nios2-flash-programmer: Error opening target har ware Oct 6, 2005 8:33:01 PM - (???) nios2-flash-programmer: Unable to open flash- evice after successfully communicating with target. It is likely that you are using a flash-programming FPGA design which was not created for your target board. -------------------------------------------- I think I am not doing totally wrong, since I can write something into EPCS using nios2-flash-programmer, and it seems to work just fine. Any advice will be great.Link Copied

Hi fuji,
Sorry about the last post ... I fat-fingered it ... still getting used to the new buttons ;-) > SOPC Builder]$ nios2-flash-programmer --input=xxx_fpga.flash > --sof=d:/doors_h ome/xxx/xxx_board/system/xxx_board.sof --base=0x00800000 Did you create the xxx_fpga.flash file with sof2flash? What parameters did you use? Regards, --Scott- Mark as New

Hello,
Thank you very much, smcnutt and eltonlaonong. I think my problem is that the flash we use is NOT cfi flash. The flash driver we made works good. We had a cyclone evaluation board at hand, so we made totally new files assumming this being a custom board, and Flash Programmer worked just fine. I guess there was nothing wrong with the procedures we took to make our own custom board. I saw some posts with similar problem using non cfi flash. Is there anyway I can use Flash Programmer on non cfi flash?- Mark as New

I'm still waiting for an answer on that one. Basically, you'd have to write your own flash programmer target code for your target board, but you have to know the flash programmer's protocol on the JTAG UART in order to do that.

I got around the problem by doing a separate configuration for the PLD, containing a small program in internal-ROM to accept the flash HEX data from a serial port and write programming instructions to the flash.
