Honored ContributorI have tried a simple test, using the pre-built target board flash programmer. Apart from a Java application erro at the very end, it sucessfully programs the EPC device on my Nios Cyclone Devkit via the JTag connector.
So..... the .sof pre-built programmer from Altera for the dev-kit works okay. However, if I try to build my own target_board (for the nios devkit) using this line:- ml_target_board --name=dev_kit_board_test --family=cyclone --clock=50 --index=1 --buffer_size=16384 --epcs=U59 and try to then use this flash programmer design the failure is as follows, so this 'Unrecognized EPCS device ID: -1' must be a problem with my tools? Is it possible to get the source-design for the Altera Flash Programmer, since it clearly works - and presumaly it was generated using the mk_target_board utility? If this is the case, what exact command-line parameters were used? http://forum.niosforum.com/work2/style_emoticons/<#EMO_DIR#>/ohmy.gif make: Entering directory `/cygdrive/f/projects/devkit/full_featured/software/devkit_standalone_test/Release' nios2-flash-programmer --input=ext_flash.flash --sof=`F:/altera/quartus41/sopc_builder/bin/find_sopc_component_dir dev_kit_board_test`/system/dev_kit_board_test.sof --device=1 --base=0x00800000 31-Jan-2005 15:36:08 - (INFO) nios2-flash-programmer: Input file empty--no data to program into flash.

It is likely that you are using a flash-programming FPGA design which was not created for your target board. In order to program flash, you must first create a purpose-built flash-programming design (i.e. FPGA configuration) and associate it with your particular board. The Nios development kit is delivered with purpose-built flash-programming designs pre-built for several development boards. If you wish to program flash on your own board, you must first create a flash-programming design. The process of creating a flash-programming design for your board is mostly automated. From a bash-shell, execute this script: mk_target_board --help The help-message includes references to other documentation on programming flash and targeting Nios systems to custom board designs. - exiting. make: *** [epcs_controller_boot_rom_programflash] Error 5 make: Leaving directory `/cygdrive/f/projects/devkit/full_featured/software/devkit_standalone_test/Release'
