FPGA Enumeration Failure

Hi,

The error is being generated at boot-time of RISC-V CPU.I am using Ubuntu 21.10 OS on RISC-V CPU which has default dfl-pci modules.I am trying to program Intel Arria 10 GX Programmable Acceleration Card through RISC-V CPU(SoC) on Hifive Sifive Unmatched Board via PCI express.The kernel version of the OS is 5.13.0-1004-generic of the RISC-V CPU

Intel Accelerator Dev Stack is working properly for x86 system

I tried to install RTE and Acceleration Stack on RISC-V CPU system to program PAC card but it did not work out.Kindly provide suitable solution to the problem

Thanks&Regards

Hi,

I have installed OPAE-SDK in RISC-V CPU.I have also installed OPAE-Intel FPGA Device Drivers from sorce packages available in git-hub.I am able to remove the boot-time error by loading OPAE drivers in place of DFL.I am facing error while running 'sudo fpgainfo fme'.I am attaching the screenshot of the error.Kindly suggest solution to the problem

Thanks&Regards

Hi,

I am loading intel-fpga-pci instead of dfl-pci using 'mv' command.The name of the module is dfl-pci but actual module getting loaded is intel-fpga-pci and I am unable to see the kernel driver.Are kernel modules and drivers same??.Kindly reply

Thanks&Regards

Hi,

Intel Arria 10 PAC card is working properly,the drivers got installed and able to run applications on them in x86 based server systems,But facing issues while trying to do the same with RISC-V CPU

Is it possible to program Intel PAC card through RISC-V CPU using JTAG.RISC-V CPU(SoC) based Hifive Sifive Unmatched Board has a support for JTAG.What are the steps that are to be implemeted to program Intel PAC card through JTAG.Kindly mention.

Thanks&Regards
