AS configuration with SPANSION SPI flash

Hello,

I try to program my Cyclone III (EP3C16) though AS configuration. I do not used EPCS but a SPANSION S25FL016A0LMFI001 which have the same Silicon ID than the EPCS16 (14h) and with the same opcode (ABh).

So when I try to program the SPANSION flash with Quartus II programmer (7.2 SP1) I have the following message :

Error: Can't recognize silicon ID for device 1

So what could I do and look at to solve it ?

Thanks for your collaboration

    AS mode is reserved for Altera configuration devices. You have to switch to PS mode.

    No you can still use the Spansion flash. Now how are you trying to progam it? Are you using the active serial method, the JTAG indirect method, or the nios2-flash-programmer method?

    Here this thread on the NIOS forum might give you some insight:

    I am using the JTAG indirect method with the Quartus II programmer (used in AS mode) with USB blaster connecting to the JTAG port of the FPGA.

    If you are doing the JTAG indirect method (using a .jic file). Then you want the programmer in JTAG mode not Active Serial Mode.

    I thought that the JTAG indirect method used the .pof file :confused: . I translate the .pof file in .jic with EPC3 loader and now it seems good :) .

    Thanks a lot for your help.

    Glad it's working. You may have noticed the JIC method can be a bit slow. If you plan to do this for manufacturing, you may wish to look at using the nios2-flash-programmer as a faster alternative.
