Can’t find Nios2config.

Hello janhendrik,

the „nios2configtool” is a script which can only be executed out of the Nios II SDK Shell (command line). Take a look at “eCos for Nios II.htm” to get some “getting started” information. Chapter 5 says that Quartus 4.1 or greater and Nios II 1.0.1 (SP 1) are needed.

Hi niosIIuser,

That is my whole problem. The nios2configtool script does not seem to be installed. It's not a big problem since I was able to get a library to compile by starting the config tool manually, and udjusting the ptf file manually. I was merely wondering why i could not find the nios2configtool from the command prompt. The PATH variable seems to include all the eCos directories.

Do I need to upload a eCos kernel, like I have to do with uClinux or do I simply upload the hello ELF file? [for the first example]

Will eCos 2.0 work with a time limited Nios II processor.? I.E. will it load the right _time_limited.sof file?

Hello janhendrik,

mmh, ok now I understand what does not work correctly. I don’t have any experiences with eCos or uCLinux, so I’m not the right person for these problems.

I installed eCos and executing “nios2configtool” was no problem. Also making the examples was fine. But now it is not possible to execute “program_flash”. Perhaps your and my problem is similar.

BTW: How can I check the path variable in the shell?

Hi niosIIuser,

Yip, seems like we're stuck on the same page.

To check the SOPC builder PATH variable, type : $PATH in the SDK shell.

Mine gives :

Not sure why it says No such file or directory, as that shouldn&#39;t be so.

BTW, Did you run "program_flash" from the diecroty into which you copied the example file?

There should be a hello file that is about 1MB in size.

my eCos Lib file directory is c:\altera\kits\ecos\test_install test_build and test_mlt.

my eCos examples directory is c:\altera\lits\ecos\examples.

so to upload the hello elf file i run the following command from the examples directry:

/cygdrive/c/altera/kits/ecos/test_install/program_flash hello

../test_install/program_flash hello would also work.

You basically run the program_flash script from the _install directory, while still in the examples directory.

program_flash then uploaded the hello file, but my nios2-terminal never responded

Does it work for you?

Hello janhendrik,

Thanks for the tip with the path. My mistake was to write "$PATCH" in lower cases! Now is working fine.

$ $PATH
bash: /cygdrive/d/quartus41/niosII10/components/ecos/ecos-2.0/tools/bin:/cygdriv
e/d/quartus41/niosII10/components/ecos/ecos-2.0/packages/hal/nios2/tools/bin:/bi
n:/usr/bin:/cygdrive/d/quartus41/niosII10/bin:/cygdrive/d/quartus41/niosII10/bin
/nios2-gnutools/H-i686-pc-cygwin/bin:/cygdrive/d/quartus41/niosII10/bin/fs2/bin:

/quartus41/bin/perl561/bin:/cygdrive/d/quartus41/bin/gnu:/cygdrive/d/quartus41/s
opc_builder/bin:/bin:/usr/bin: No such file or directory

I did also a failure when trying to upload the flash file. Now it would work but I had to give the development board back to Altera. Tomorrow I will try to get it work with my own hardware. There are some differences to the DK. http://forum.niosforum.com/work2/style_emoticons/<#EMO_DIR#>/wink.gif

A couple of pointers that might help.

1. The nios2configtool application is in the directory:

$ECOS_REPOSITORY/hal/nios2/tools/bin

This should be automatically added to your path if you are using an SDK shell. However this may not happen if you are using an old version of Quartus, in which case you can just add the directory to your path manually.

2. The Altera flash programmer programs the device with it&#39;s own SOF file. Therefore after running the "program_flash" script, you will need to remember to reprogram the device with your original SOF before you can do anything.

Hope that helps.

Typing just $PATH directly into the shell will try and EXECUTE the $PATH variable as a command! Hence your error message. If your path variable had contained &#39;rm *&#39;, you&#39;d have said goodbye to all your files.

To view $PATH, try &#39;echo $PATH&#39;, or &#39;printenv&#39;.

Both are much safer!

Hello,

The first steps are done. The custom board is sending “Hello, eCos world!” over the JTAG UART! That’s really nice.

Might it be possible to integrate eCos into the Nios II IDE?

Bye,

a lucky niosIIuser

PS: Thanks to roddy for the $PATCH tip.
