XK-EVK-XU316: accessing the GPIO Topic is solved

[HerbieSundiver]

Hi guys,

sorry that this is a bit off-topic but I do not even get this exact example compiled...
I get this:

I'M grateful for any kind of help.

Thanks,

Hello Sun, I feel you, getting started with this XMOS project isn't super easy.
My recommendation is to download the entire release package: https://github.com/xmos/sw_usb_audio/re ... _8.0.0.zip
It contains all the libraries that are needed as dependencies (which is what you're missing).

Another approach is to set up the libraries as git submodules, which is what I did. But try to compile from the zipped release first.

Hi Harold,
thanks for your quick reply!
Yes, I used the zip file as it is but get the above error...albeit I see all the libs in their separate folders.

Its so frustrating, I tried the "sw_usb_audio-[sw]_v8_0_0" on virtual machines: Ubuntu, Fedora and on native Ubuntu. None of them works!?
Here's what I get:

It shouldn't be that hard to compile an existing example, right? What am I missing?
Should I rather prepare a PC with an english win10 version?

Any help is welcome...

How did you set up the XTC tools?
I recommend doing it like this:

1. Download the latest XMOS XTC software tools
2. Extract the archive into a folder, for example: `/home/$USER/XMOS/XTC/15.2.1/`
3. In the script located at `/home/$USER/XMOS/XTC/15.2.1/SetEnv`, you will find the assignment `SCRIPT_PATH=$PWD` at the top. Substitute `$PWD` with the folder where your tools are actually located (in our example, it's `/home/$USER/XMOS/XTC/15.2.1/`)
4. If you're using `zsh`, open the configuration file `/home/$USER/.zshrc` and add this line at the end: `source /home/$USER/XMOS/XTC/15.2.1/SetEnv`. This will make the XMOS tools available every time you open the command line.
5. If you're using `bash`, do the same as described step 4., but edit `/home/$USER/.bashrc` instead.

Hi Harold,
thanks again for this hint, that is nice as I do not have to start the terminal in the tools folder and then work my way through...
BUT: Unfortunately it does not change the "xmake all" behaviour:

In the Makefile (the one in the "app_usb_aud_xk_evk_xu316" folder) I see "USED_MODULES = lib_xua lib_i2c" and "# Modules are expected to be in the directory above the BASE_DIR directory."
Do I have to copy the libs into the folder "sw_usb_audio", so above the folde the Makefile is in?

On the other hand, the Makefile in the "sw_usb_audio" folder seems to refer down into each app folder. starting "xmake all" in the "sw_usb_audio" folder gives the same problems, but the libs are present in the "sw_usb_audio-[sw]_v8_0_0" folder, so I don't get it...

Or do I have to use the older XMOS tool set 15.1.4. on which the release was tested??

I will setup an english Win10 machine anyway to see how it behaves...

Best regards,
Sun

[HerbieSundiver]

update: Same errors with tools 14.1.4 :-(

[Harold Barrel]

I'm attaching my folder structure, do you have it the same?

[HerbieSundiver]

Hi Harold,
no, my structure is un-altered the 8.0.0 version (see attached)
Do I have to move things around?

Regards,
Bert

[Ross]

we don't do any testing on linux, that might be the issue. I would expect it to work though...

You could try the new cmake based build
