Flash Programmer
Flash only flow failure in IDE—Updated December 19, 2005
The Flash only flow of the Board Description Editor is used to run the Nios II Flash Programmer on a custom board in IDE mode. When the Board Description Editor is run in the Flash Flow only, wherein no board netlist (wirelist) is provided, the resulting PTF file is missing some entries which are required for successful system generation in SOPC Builder. A subsequent attempt to generate in SOPC Builder will issue the following error:
C:/altera/quartus51/sopc_builder/bin/europa/e_project.pm 310 CALLED (e_project::device_family) WHERE <=== 'expected exactly one argument' OCCURRED on C:/altera/quartus51/sopc_builder/bin/europa/e_project.pm 1313
Workaround: The workaround is to use the Flash Programmer via command line or hand-edit the board description PTF file as described below after running the Board Description Editor.
1. Run through the Flash Flow of the Board Description Editor as instructed in the Board Description Editor (PDF) chapter of the SOPC Builder Handbook.
2. Close SOPC Builder
3. In a text editor, open the .ptf file created by the Board Description Editor.
4. In the CLASS/BOARD_DEFAULTS section of the .ptf file, add the following entries.
o device_family = "<device family>"; suitable values for <device family> are CYCLONE, CYCLONEII, STRATIX, STRATIXII, etc.
o For each CFI or EPCS flash entered in the board description, create a REFDES section with an arbitrary base address, such as just "0".
o Workaround_example.txt shows an example of the edits.
5. Save and close the .ptf file after making the edits.
6. Re-open the system in SOPC Builder, select the newly created board description in the "Target" section, and then click Generate.
