Re: configure kernel fails

Altera_Forum · ‎10-11-2004

when i want to configure my kernel in the drop down menu, the window opens shortly and closes a second later. normally opens the blue configuration window, but here only the bash window for just a moment. i tried it with different kernels, it's always the same.

knows someone this problem????

thx

That's a known problem... could've sworn there was a thread about this earlier that I could point you to. Anyhoo...

The only tested and true method of debugging this issue is:

(1) modify the configure.bat file in your kernel project within the Nios II IDE

(2) remove the @start from the beginning of the line in the batch file

(3) open up a regular command prompt (not a Nios II SDK Shell)

(3a) run cd ...altera\kits\nios2\bin\eclipse\workspace\<kernel project>

(3b) run configure.bat

You should now be able to view the error messages.

Common issues:

gcc or nios2-elf-gcc not found...

... you may need to run SOPC Builder at least once in order for your Quartus II/SOPC Builder installation to be complete. After running SOPC Builder, try configuring the kernel again

crt0.o not found...

... this is trickier, you need to double check that a crt0.o file exists within the ...quartus/bin/cygwin/usr/lib directory. This is the one that the kernel configuration is trying to link against. If it's there then something is different about your mount points than what we expect it to be. We typically unmount the current /usr/lib if it's mounted, so you may try that from the Nios II SDK Shell before attempting to configure your kernel again.

any other error messages, let me know...

I've had a similar problem on a system on which a standalone copy of Cygwin was installed. I'm guessing that the uClinux installer found Cygwin and not Quartus' Cygwin, which led to some kind of problem finding gcc. I couldn't get Cygwin and Quartus Cygwin to coexist, so I uninstalled Cygwin, reinstalled uClinux, and it all worked.

If the installer asks you for the location of Cygwin, make sure you point it to Quartus II 4.0's Cygwin.
