PCIe DMA transfer design code Compilation error.

I was trying to compile the DE5A_NET.qpf file of the `DE5a-Net-DDR4_v.1.0.9_SystemCD/Demonstrations/PCIe_DDR4/` in Quartus Prime Pro version21.4, getting some compilation error and the error message...

Hi Travis,


Thanks for such a detailed reply and the printscreen picture.

If refer to Capture 2 for error "Error: Unexpected error writing the ensemble: java.io.FileNotFoundException:"

Can you please check if The software was installed under Program Files folder ?

  • If YES, I would suggest you to try unistalled Quartus Suite and installed again on root directory (C:\Altera).
  • Probably the problem was the space in the installation path ("Program Files").
  • and you try and generate one of the example designs that is located in the default installation.
  • You can workaround this error by copying the example design from the installation directory into a new directory elsewhere on the PC.
  • Or maybe change the owner of the directory,


Let me know if the problem solved.

Regards,

Wincent_Intel

Our installation of Quartus Prime Pro 21.4 is not under the "Program Files" Directory. It is located with a file path: C:/intelFPGA_pro folder.

Copying example projects out onto our Desktop allows for two different .qpf files to compile successfully after minor updates to our current version (specifically the Quartus Design Files of "DE5a-Net-DDR4_v.1.0.9_SystemCD/Demonstration/Hello" and "DE5a-Net-DDR4_v.1.0.9_SystemCD/Demonstrations/NIOS_DDR4_X2"). The testbech and DHL generating are done for both examples (using their associated .qsys files) without having any error .

However, our project ("DE5a-Net-DDR4_v.1.0.9_SystemCD/Demonstrations/PCIe_DDR4/") containing ep_g3x8_avmm256_integrated.qsys continues to get held up at the "Generate Testbench" Step in Platform Designer after the automatic updates. (Screenshot 67, Screenshot 68)

Screenshot 66 just indicates that our project doesn't compile by default.

We are thinking about Installing an older version of Quartus Prime Pro such as 18.1. As well as possibly uninstalling completely and then creating an Altera folder and installing Quartus Prime Pro there.

We already have enabled the write and read permissions of the C:/intelFPGA_pro/21.4/ip/altera folder as a whole for all users.

Thank you for your suggestions on helping us to run the PCIe DMA transfer sample project.
