Flash Programmer in NIOS2 1.1

In Nios2 1.01, I have used the Flash Programmer well.

But, in Nios2 1.1, I encountered the problem as following.

There are a CPLD and FPGA On my board. And FPGA is index 2 on the JTAG Chain.

I made the correct setting at the Flash Programmer Design which has a FPGA at index 2 of the JTAG Chain.

If you have the answer, please help me.

    I have some idea, but I'm not sure that it helps you.

    Try to readd a JTAG_UART in your configuration design and recompile all.

    JtagUart in new version of NIOS 1.1 is different from NIOS 1.01.

    I had the same problem - and a solution...

    There is a bug in the nios IDE in Version 1.1 which don't forward the fpga jtag-chain position to the flash programmer. So you have to do it per hand.

    Adjust all settings in the flash-programmer window - press "Apply". Then the IDE generates a file called "xx_programmer.sh" (where xx is the name of the project). You can find this file in the xx/debug/ folder. Open it with a text editor - find the lines where the flash programmer gets called (these lines start with "$SOPC_KIT_NIOS2/bin/nios2-flash-programmer") and add " --device=n" at the end of these lines - replace "n" with the jtag-chain position of the fpga - with 2 in your case. Do this as often as the flash programmer is called in this file (two times in my case) then save the file.

    Close and reopen the Flash-Programmer window in the nios IDE and press "Program Flash". DO NOT PRESS "APPLY" - or you have to do the modifications again.

    guys from altera : please add this to your fix-list for the next update...

    Thanks for highlighting this problem. We'll be looking to address this in an upcoming release of Nios II IDE.
