unable to find FTD2XX library path

Hi,

When i use

h=aximanager('AMD','JTAGCableType','FTDI');

in Ubuntu 20.04 LTS system.

An error occurs:

error using fpgadebug_mex

failed to open FTDI JTAG cable: Unable to find FTD2XX library path'

Error in hdlverifier.AXIManagerJTAG/openCable

Error in hdlverifier.AXIManagerJTAG

However, the ftd2xx driver has been installed on my computer.

Hi KH,

The error 'Unable to find FTD2XX library path' typically appears when the user has not installed the 'HDL Verifier Support Package for AMD FPGA and SoC Devices' on their host MATLAB system.

Can you check the "Add-Ons" section on your installed MATLAB and confirm the above mentioned SPKG name in the "Add-Ons -> Manage Add-Ons"?

Thanks,

Heman, P

Hi,

Thanks for your reply.

I just checked my add-ons. ''HDL Verifier Support package for amd fpga and soc devices'' has been installed. And the fpga in loop test passes? Should I re-install the package?

Hi KH,

Investigated and came to know that our AXI Manager codebase is currently unable to retrieve the SPKG installation path for the FTD2XX library on the Linux platform.

As a result, you are facing the error message: 'Failed to open FTDI JTAG cable: Unable to find FTD2XX library path.'

But the same issue is not there with Windows platform.

This confirms the necessity for an update on the Linux side to correctly return the path.

Since, this pertains to the internal codebase of the AXI Manager script, we will address this issue through an SPKG update for the affected versions.

In the meantime, we can provide you with a working patch file to ensure that you can continue using the AXI Manager functionality without any disruption to your application.

Could you please specify the version of MATLAB you are using?

Thanks,

Heman, P

Thanks for your reply, I'll solve the problem later.

The matlab version I use is 2024b.

Hi KT,

Please find the patch file 'AXIManagerJTAG.zip' from the attachment.

This zip file contains the 'AXIManagerJTAG.p' MATLAB p-code file, compatible with MATLAB version R2024b on Linux.

Copy the file ‘AXIManagerJTAG.p’ to the SPKG installation path:

"/home/<user_name>/Documents/MATLAB/SupportPackages/R2024b/toolbox/hdlverifier/supportpackages/fpgadebug/+hdlverifier"

After copying the file, launch the MATLAB and perform the following commands on MATLAB console:

>> rehash toolbox

>> rehash toolboxcache

Please let me know if this patch file works in your setup environment.

Thanks,

Heman, P
