I can see a reference to libusb.
Are you using a USB to LPT port adapter?   
Those are intended for printers and do not implement a full hardware LPT port with all the hardware registers.
To get a proper printer port you need either one built onto the motherboard or added with PCI/PCIe card.

If you are using a proper hardware LPT port, check if you have permission to access the /dev/parport0 devices

I am using FT2232H which does USB-to-JTAG

See https://ftdichip.com/wp-content/uploads/2020/07/AN_129_FTDI_Hi_Speed_USB_To_JTAG_Example.pdf

As in why IMPACT tool requires parallel LPT port, I have no idea at all.

[bingo600]

To me it seems like it has problems detecting the usb cable.

And because the cable type is set to Auto , it tries parport as other option.

The JTAG cable detection issue is solved by inserting "source /opt/Xilinx/14.7/ISE_DS/settings64.sh" into $HOME/.bashrc

However, I still have the following CRC error even though IMPACT tool said that bitstream loading is completed.

You might try DigilentInc's Adept software as a stand-alone programming tool.  I haven't played with 14.7 in a long time but it seems to me that I was always using Adept rather than Impact.  I have never used it on Linux.

https://store.digilentinc.com/digilent-adept/

ETA:  I do know that Adept works on Linux because it is required for Waveforms.  I just haven't used it with ISE.

@rstofer

Thanks for your link, but I am already using https://wiki.archlinux.org/index.php/Xilinx_ISE_WebPACK#Digilent_USB-JTAG_Drivers

[rstofer]

@promach

You may have the correct drivers but the problem is likely with Impact.

That you are having a problem is no surprise to Xilinx:

https://www.xilinx.com/support/answers/20762.html

Among other things, Impact is not supported under Linux 64 bit other than RedHat.

[promach]

@rstofer

Thanks for the Xilinx website link and  your advice, setup_pcusb is actually already settled by https://wiki.archlinux.org/index.php/Xilinx_ISE_WebPACK#Xilinx_Platform_Cable_USB-JTAG_Drivers though

[jmelson]

Among other things, Impact is not supported under Linux 64 bit other than RedHat.

I use Impact just fine on an Ubuntu 12.04 x64 system.  Did I have to install a library?  Quite possible, it has been a while.

I'm running ISE 14.7 with no problems on a Mint 17.3 x64 -  (Ubuntu 16.04 base i think).
I use a $20 Xilinx clone programmer (the one that looks like the original)
I seem to remember that i had to set an environment variable telling impact to use LIBUSB

The real root cause for my JTAG cable detection issue is due to the unreliable PHYSICAL cable wire connection, in other words, signal integrity issue.

I am able to connect and detect JTAG adapter cable now, but I am pretty sure this issue will haunt me in the future again.

By the way, for those looking for some solution, insert the following two lines into $HOME/.bashrc

Code: [Select]

export LD_PRELOAD=/opt/Xilinx/usb-driver/libusb-driver.so
source /opt/Xilinx/14.7/ISE_DS/settings64.sh

Besides, why the generation error for chipscope ?

    ERROR:sim - Failed to generate file: chipscope_vio_xmdf_tcl
    ERROR:sim - Error found during generation.
