Error: unable to open ftdi device with description '*', serial '*' at bus location '*' about linux-on-litex-vexriscv HOT 13 CLOSED

Your target is an arty. This one has an FTDI with official VID/PID (0403:6010), but there is no FTDI in your lspci dump.
Are you sure to have an arty board?

from linux-on-litex-vexriscv.

I have an Artix 7, but I redid it with the target as arty_a7 and got the same result. I followed the installation as instructed.

In the link above, I know for sure that I have an Artix-7... is there something else I need to specify?

from linux-on-litex-vexriscv.

Ok: with the board's link it's more clear ;-)
It's not an arty but another artix7 based board (maybe compatible -> you have to check/compare pinout, RAM, etc...).
With the arty you have an FTDI to program/load bitstream and to have an serial interface, here its through an FX2 and/or an external JTAG interface: this why openocd is unable to find an FTDI device.

from linux-on-litex-vexriscv.

What extra arguments would I need to input besides ./make.py --build=arty_a7 --cpu-count=1 --load?

As well, would there be anything I would need to change when building the project, since I input ./make.py --build=arty_a7 --cpu-count=1 --build currently.

It also supports configuration via USB, how could I make this possible as this might be easier for me?

from linux-on-litex-vexriscv.

One thing not clear to me: why using digilent arty a7?
Your board is supported by litex-boards, you have to add a new entry/config in make.py.
About JTAG interface: the best way is to connect an external USB<->JTAG to CON5.

from linux-on-litex-vexriscv.

So I have the external USB <-> JTAG to CON5 connected. I'm not sure why the error from OpenOCD is popping up. Is there something else wrong?

from linux-on-litex-vexriscv.

Jack is for power supply
mini USB connector for FX2
Could you tell me name of the external USB<-> you have used?
If you persist to use arty target, errors may be:

• a different FTDI than the one on this board
• access right: your user is not in the FTDI's group owner

from linux-on-litex-vexriscv.

Are you referencing the cord I am using, or the port I am using?

from linux-on-litex-vexriscv.

Port. Both on this picture aren't relative to the programming with and FTDI external device.
You have to populate CON5 (near RAM chip) and connect your external probe here.

from linux-on-litex-vexriscv.

So I can't use CON2 (Micro-usb)?

from linux-on-litex-vexriscv.

Once again: CON2 is connected to an FX2 device, with a specific protocol. It's not an FTDI device, it's not compatible with an FTDI device and consequently openocd will not be able to do something with this device.
Yes I assume it's possible to use it with a tool provided by ztex. But until to you stop to confuse between ztex board and digilent board you will not be able to load/program your board.
And since this board it's not an arty the bitstream generated will not works with your board. I haven't checked the schematic but there is a great chance the pinout is different than digilent arty board (both board are based on ARTIX but it's two differents boards) (I have pointed correct platform/target).

Hi @jjagielo,

please first read https://github.com/enjoy-digital/litex/wiki/Feedback-Contribution-Support. Here it seems you are confusing Arty (the Digilent Arty) with Artix-7 (the Xilinx FPGA). To run the project on your board, you first need to add support for your board in the project, which is not currently the case.

However, it seems that the support is present in LiteX-Boards, so running the project on it would be possible. As a first step, you'll have to get test the LiteX-Boards target on your hardware: https://github.com/litex-hub/litex-boards/blob/master/litex_boards/targets/ztex213.py

When you get it working with default settings and are able to load your FPGA, adding the support for the project will consist at listing it on board.py with the right configuration.
