ViP Example using the Cyclone III Development board

Additional information...

I deleted all the files and rebuilt the project in NIOS 2. It connects and downloads the program.

I closed NIOS 2, then reopened the vip_example files. Now I have an error in main.cpp. The ISR_timer_interrupt routine gives the following error message.

"Function '_builtin_stwio" could not be resolved. This is in the line IOWR_ALTERA_AVALON_TIMER_STATUS (base, 0);

Tracked down the problem to the "io.h" include file. It has the following lines.

# ifndef SYSTEM_BUS_WIDTH

# error SYSTEM_BUS_WIDTH undefined (this line is marked "error with text")

# endif

It later makes the following definitions.

# define __IO_CALC_ADDRESS_NATIVE(BASE, REGNUM)

((void *)(((alt_u8*)BASE) + ((REGNUM) * (SYSTEM_BUS_WIDTH/8))))

# define IORD(BASE, REGNUM)

__builtin_ldwio (__IO_CALC_ADDRESS_NATIVE ((BASE), (REGNUM)))

# define IOWR(BASE, REGNUM, DATA)

__builtin_stwio (__IO_CALC_ADDRESS_NATIVE ((BASE), (REGNUM)), (DATA))

The error I received after reloading in Eclipse is "Function '_builtin_stwio' could not be resolved.

I have no idea where SYSTEM_BUS_WIDTH is defined.

Hi Ted!

No, still using nios2-elf-gcc. But, I did the "Clean" and "Build" as you suggested. I see the following information at the end of the transcript.

This problem is probably due to using incompatible versions of the cygwin DLL.

Search for cygwin1.dll using the Windows Start->Find/Search facility

and delete all but the most recent version. The most recent version *should*

reside in x:\cygwin\bin, where 'x' is the drive on which you have

installed the cygwin distribution. Rebooting is also suggested if you

are unable to find another cygwin DLL.

make: *** [vip_control.elf] Error 139

make: *** Deleting file `vip_control.elf'

**** Build Finished ****

I found 2 files with that name, both in my \altera\13.0sp1\quartus folder.

First one is in \bin64\cygwin\bin

Second one is in \bin\cygwin\bin

I am guessing that the software I have was built with an earlier version of Quartus and I may have a compatibility issue.

I receive an error. "connected system ID hash not found on target at expected base address".

The debug/download in eclipse is pretty flaky in my experience. Try deleting and then re-creating the profile under "Nios II Hardware".

I had this problem too, until I turned off "Codan Analysis UI for C/C++".

I found this post here (http://www.alteraforum.com/forum/showthread.php?t=40002) very helpful (post# 5).

Thanks, I no longer see the error. Now to figure out why I have no video.

Still seeing the failure to connect for downloading, but the file does download from the command shell.

It takes some effort, but I can get the download and debug to work.

The "Clear Screen" fails during initialization. I can step through the process until i=9, then the board stops responding.

Since the board was qualified with QuartusII 12, I am trying to download and install that version.
