Is there anyway to specify the install dir of the FPGA tools?

ShawnLess commented 6 years ago

Hey guys: Nice work but I still ran into problem after I installed the Xilinx tools:

-bash-4.1$ ./make.py all

      __   _ __      ___  _________
     / /  (_) /____ / _ \/ ___/  _/__
    / /__/ / __/ -_) ___/ /___/ // -_)
   /____/_/\__/\__/_/   \___/___/\__/

  A small footprint and configurable PCIe
          core powered by Migen
====== Building options: ======
Platform:  kc705
Target:    dma
Subtarget: PCIeDMASoC

FileNotFoundError: [Errno 2] No such file or directory: '/opt/Xilinx/Vivado

I installed the vivado in a dir other than /opt/Xilinx/Vivado. How can I change that? I there any parameter that I can override on command line?

Thanks in advance.

You can try to use toolchain_path="your_toolchain_path" here: https://github.com/enjoy-digital/litepcie/blob/master/example_designs/make.py#L154

Note that if you want to build this example design, you will need to have a valid license for a xc7k325t. I should add an example design for artix7 too.

Hi :

Thanks for the kind reminder. I will check if we have that license feature.

Anywhere, is it possible to generated RTL only? we don’t need bitstream at this stage.

Regards, Shaolin.

Adding toolchain_path="your_toolchain_path" to: https://github.com/enjoy-digital/litepcie/blob/master/example_designs/make.py#L154 worked perfectly.

Anywhere, I lack the license to generate the bitstream.

Closing since solved.
