Dear all,

The problem ended up being an alias on our machine, which was pointing to another MATLAB license - this one deprived of the toolboxes. After finding this out, it seems we were able to run MATLAB and the toolboxes properly.

Thanks to Jack and to those who helped off-list,

Matheus

Hi Matheus,

I've never had a problem with Ubuntu 14 and MATLAB 2013b. In fact I sometimes do ROACH2 builds on Ubuntu 16.04 which is also fine. In general, almost all of my problems come from Xilinx, not MATLAB.

However, you are absolutely right that MATLAB 2013b seems to only support Ubuntu 13.04 (reasonable, I guess, since 2014 hadn't happened yet!). I guess my only suggestion, since you're using a VM, would be to try Ubuntu 12.04 and see if that helps. If I remember correctly, even though most people use Ubuntu these days, the "officially supported" OS for ROACH2 compiles was Red Hat (or CentOS) 6, which is also an option. This is in the support list of both MATLAB 2013b and Xilinx ISE 14.7

Cheers
Jack

    Dear all,

    We have been facing some issues with our MATLAB installation. After
    checking the compatibility matrix on the CASPER "Installing the
    Toolflow" website
    
(https://casper-toolflow.readthedocs.io/en/latest/src/Installing-the-Toolflow.html
    
<https://casper-toolflow.readthedocs.io/en/latest/src/Installing-the-Toolflow.html>),

    we contacted our software provider to request a MATLAB R2013b
    trial license,
    together with the needed toolboxes (Signal Processing, DSP System and
    Fixed-Point Designer). We are programmng a ROACH2 board.

    However, after the installation, we found out that the toolboxes were
    not being recognized by MATLAB and asked for support from the same
    provider. Following a lengthy conversation, we were told that the
    most
    likely reason was that MATLAB R2013b was meant to run on Ubuntu
    12.04,
    12.10 or 13.04, not on Ubuntu 14. Not being an expert when it
    comes to
    Linux/Ubuntu, I want to ask you if this may be the reason for our
    issues. Are we meant to use another version of Ubuntu/MATLAB than
    those
    shown on the compatibility matrix?

    Right now we are using a virtual machine running Ubuntu 14.04.6
    LTS on a
    Oracle VM VirtualBox, while the host machine runs Ubuntu 20.04.2 LTS.

    Best regards,

    Matheus
