NIOSII problems?

I picked up and installed my USB Blaster cable today and was looking forward to working through a NIOSII tutorial and communicating proprely with the eval board.

However when I'd installed the cable and tried to run through one fo the tutorials I got the following error...

make: *** [do_delete_placeholder_warning] Error 1

After some messing about I got a report saying that I had more than one cygwin1.dll on my machine and that I should delete all but the latest. I did this and now compiling I get

make: *** [do_delete_placeholder_warning] Error 255

I get this error for all the tutorial designs/applications.

Has anyone else sen anything like this, and can anyone suggest how to fix this? I've spent the night looking at it and am about to start pulling hair out.

Tonight is the first time I've seen this problem, and I have re-booted since installing the USB Blaster. OP is win2K.

Thanks in advance for any help,

the cygwin compatibility DLL is one major incompatibility issue :( lots of tools install cygwin somewhere, then you get new tools that require newer version, and maybe install the new one, and then you are doomed.

its the best to get latest cygwin and keep it in c:\cygwin\

but.. some tools may need to use some special version of cygwin and may not like the newer one, in that case you need to hide the new version as you complaints otherwise. Deleting the cygwin1.dll from the tool folder(s) and trying to use the cygwin1.dll from c:\cygwin\ sometimes does not work

-- sometimes I think its faster easier and cheaper to buy a fresh new PC for every FPGA toolchain. Get new PC install one application and use it for that applicaton.

an old windows installation gets some so garbaged with different dll releases different drivers for security dongles. etc, a possible nightmare

unfortunatly I dont know the quick answer for your problem, so the painful path possible, reinstall everything try again, if no help get temporary new empty PC/windows install there, verify it works there then try to duplicate the install on the workstation

Shared/duplicated .dlls are a weak point for a windows host. Sometimes I think it may be faster easier and cheaper to bite the bullet and try Altera's linux host software.

Did you try the NIOS forum?

What you _could_ do, is have a removable hard drive (cradle adaptor), or maybe one based on newer, very fast serial links. (not as cheap) Then, each tool has its own resource, but you still hope that the windows area remains OK, - the degeneration effects should be reduced.
