Pin assignment problem---FlashRom Open Drain

[Altera_Forum]

Now I want to use the Cyclone III starter board to read or write FlashRom, 

But when I　ｃｏｍｐｉｌｅ　ｍｙ　ｐｒｏｊｅｃｔ　，Ｉ　ｅｎｃｏｕｎｔｅｒ　ｍａｎｙ　ｂｅｌｏｗ　ｅｒｒｏｒ．  Ｉｎ　ｔｈｅ　ｄｅｖｉｃｅ　ａｎｄ　ｐｉｎ　ｏｐｔｉｏｎｓ，　Ｉ　ｓｅｔ all　ｔｈｅ　Ｄｕａｌ-Purpose Pins as Use as regular I/O. Now I cant correct the error.  Please help me.  Thank you!  Error: Following feature(s) of I/O pin FLASH_DATA[15] has invalid setting(s) in configuration scheme ACTIVE_PARALLEL_FLASH when the pin is placed at pin location B6  Info: The IO feature 'Open Drain' has invalid setting, it should set to OFF Error: Following feature(s) of I/O pin FLASH_DATA[14] has invalid setting(s) in configuration scheme ACTIVE_PARALLEL_FLASH when the pin is placed at pin location A5  Info: The IO feature 'Open Drain' has invalid setting, it should set to OFF Error: Following feature(s) of I/O pin FLASH_DATA[13] has invalid setting(s) in configuration scheme ACTIVE_PARALLEL_FLASH when the pin is placed at pin location B5  Info: The IO feature 'Open Drain' has invalid setting, it should set to OFF Error: Following feature(s) of I/O pin FLASH_DATA[11] has invalid setting(s) in configuration scheme ACTIVE_PARALLEL_FLASH when the pin is placed at pin location B3  Info: The IO feature 'Open Drain' has invalid setting, it should set to OFF Error: Following feature(s) of I/O pin FLASH_DATA[10] has invalid setting(s) in configuration scheme ACTIVE_PARALLEL_FLASH when the pin is placed at pin location A3  Info: The IO feature 'Open Drain' has invalid setting, it should set to OFF Error: Following feature(s) of I/O pin FLASH_DATA[9] has invalid setting(s) in configuration scheme ACTIVE_PARALLEL_FLASH when the pin is placed at pin location E7  Info: The IO feature 'Open Drain' has invalid setting, it should set to OFF Error: Following feature(s) of I/O pin FLASH_DATA[8] has invalid setting(s) in configuration scheme ACTIVE_PARALLEL_FLASH when the pin is placed at pin location B4  Info: The IO feature 'Open Drain' has invalid setting, it should set to OFF Error: Following feature(s) of I/O pin FLASH_DATA[7] has invalid setting(s) in configuration scheme ACTIVE_PARALLEL_FLASH when the pin is placed at pin location A4  Info: The IO feature 'Open Drain' has invalid setting, it should set to OFF Error: Following feature(s) of I/O pin FLASH_DATA[6] has invalid setting(s) in configuration scheme ACTIVE_PARALLEL_FLASH when the pin is placed at pin location E8  Info: The IO feature 'Open Drain' has invalid setting, it should set to OFF Error: Following feature(s) of I/O pin FLASH_DATA[5] has invalid setting(s) in configuration scheme ACTIVE_PARALLEL_FLASH when the pin is placed at pin location C5  Info: The IO feature 'Open Drain' has invalid setting, it should set to OFF Error: Following feature(s) of I/O pin FLASH_DATA[4] has invalid setting(s) in configuration scheme ACTIVE_PARALLEL_FLASH when the pin is placed at pin location B7  Info: The IO feature 'Open Drain' has invalid setting, it should set to OFF Error: Following feature(s) of I/O pin FLASH_DATA[3] has invalid setting(s) in configuration scheme ACTIVE_PARALLEL_FLASH when the pin is placed at pin location B8  Info: The IO feature 'Open Drain' has invalid setting, it should set to OFF Error: Following feature(s) of I/O pin FLASH_DATA[2] has invalid setting(s) in configuration scheme ACTIVE_PARALLEL_FLASH when the pin is placed at pin location A8  Info: The IO feature 'Open Drain' has invalid setting, it should set to OFF Error: Following feature(s) of I/O pin FLASH_DATA[1] has invalid setting(s) in configuration scheme ACTIVE_PARALLEL_FLASH when the pin is placed at pin location D1  Info: The IO feature 'Open Drain' has invalid setting, it should set to OFF Error: Following feature(s) of I/O pin FLASH_DATA[0] has invalid setting(s) in configuration scheme ACTIVE_PARALLEL_FLASH when the pin is placed at pin location H3  Info: The IO feature 'Open Drain' has invalid setting, it should set to OFF Error: Can't fit design in device Error: Quartus II Fitter was unsuccessful. 16 errors, 6 warnings  Info: Allocated 186 megabytes of memory during processing  Error: Processing ended: Tue Apr 29 15:08:31 2008  Error: Elapsed time: 00:00:08 Error: Quartus II Full Compilation was unsuccessful. 16 errors, 94 warnings

The same error has been reported in another thread, I think. However, I don't understand where the Open Drain setting comes from, it seems inappropriate for any possible usage of the flash pins. I'm not using the board nor Cyclone III with AP configuration, so I had no occasion to experience the problem. But I know that the starter board is shipped with a fully operational example project, cycloneiii_3c25_start_niosii_standard that also uses the flash. So I first would compare with the pin configuration used in this project to understand what's wrong with your configuration.

I know that message. 

But it does not apporate for my design.  why I cannot upload my design.

is there a global assignment to turn on the open-drain in your design? 

 Anyhow, you can use individual assignment to turn off the open-drain on the active parallel flash pins.  Anthony

I'm not presently using AP configuration or the Cyclone III Dev. Kit, but as I already mentioned, it may be interesting to examine the Starter Board example designs. They have a configuration setting of active serial although the board doesn't utilize AS at all. It may be a necessary Quartus bug workaround.
