Programming the .aocx file with PCIe instead of JTAG cable

Hello guys, 

 

This command aocl program <device_name> <your_kernel_filename>.aocx is currently using JTAG cable and programming my FPGA. What should I do/ Which command should I use to program the FPGA using the PCIe interface? 

 

Thank you in advance

What is your board model/manufacturer? Unless you are forcing JTAG-based programming, aocl should try to first program the FPGA via PCI-E, and if it fails, then switch to JTAG. 

 

Also what happens if instead of programming the FPGA manually, you run your OpenCL code normally and let the FPGA be automatically reconfigured at run-time?

Hey HRZ, 

 

Using Device with name: a10gx : Arria 10 Reference Platform (acla10_ref0) 

Using Device from vendor: Intel(R) Corporation 

 

This is my dev kit https://www.altera.com/products/boards_and_kits/dev-kits/altera/kit-a10-gx-fpga.html.

Okay, and what about standard run-time reconfiguration? Does that also go through JTAG?

I get the following ouput when I compile the helloworld example and try to run the helloworld example (https://www.altera.com/support/support-resources/design-examples/design-software/opencl/hello-world....)  

 

I get this error : host: acl_pcie.cpp:71: ACL_PCIE_DEVICE* get_pcie_device(int): Assertion `0' failed. I am sure that I have connected the PCIe's well. I have installed the OpenCL image for the first time with JTAG cable.

Hello HRZ, 

 

Yeah you were right. AOCL invokes PCIe first before JTAG. I have connected both USB and PCIe but unable to program. Should I install any kind of additional drivers to program the FPGA. I am getting the error Error (213013): Programming hardware cable not detected when I run quartus_pgm -a command. I am pretty sure the PCIe is properly connected. 

 

When I run the helloworld example I get the error MMD FATAL: acl_pcie.cpp:71: can't find handle -1 -- aborting

You do not need any additional drivers to program the FPGA via JTAG. However, to program it via PCI-E, you must have correctly set up your board and installed the PCI-E driver provided by the BSP and programmed your FPGA with a base OpenCL design to enable the PCI-E core on the FPGA. 

 

If your JTAG cable is connected but quartus_pgm doesn't find it, try killing "jtagd" and then running "quartus_pgm -a" as root. In my experience, it is important that after every machine reboot, quartus_pgm is first run as root or else the cable will never be detected. After that, the cable will be detected by quartus_pgm regardless of which user is invoking it. In the next step, since it seems your PCI-E core on the FPGA is broken, you probably have to reprogram the FPGA via jtag with an OpenCL design and then reboot your machine. After that, PCI-E-based programming should work.

Hello HRZ, 

 

Thanks a lot. Your strategy works!
