Agilex 7 I-Series "aocl diagnose acl0" error following OFS

NOTE: THIS SOLUTION DOES NOT WORK. CONTINUE READING THE THREAD FOR AN UPDATED CONCLUSION

Hi,

I can confirm that AGIB027R29A1E1VB works with oneAPI support when configured for PCIe Gen4 1x16 and a 2x8 memory subsystem.

oneAPI does not work with either of the PCIe Gen 5 configurations even though I can successfully build OFS FIMs without oneAPI support for both Gen 5 1x16 and Bifurcated Gen 5 2x8 PCIe. When I try to build the oneAPI ASP with PCIe Gen 5, I encounter one of the following errors:

1. For Gen 5 1x16, the build fails due to a Verilog error in ofs-platform-afu-bbb
2. For Bifurcated Gen 5 2x8, the build succeeds but aocl diagnose acl0 times out (DMA fail)

Here are the changes that I made to get OFS and oneAPI to work with my card:

1. Follow the instructions to migrate to the AGIB027R29A1E1VB card: PCIe Attach I-Series (2xR-Tile, F-Tile) - OFS
2. Remove the two South I/O Rows. Follow steps 1-4 from PCIe Attach I-Series (2xR-Tile, F-Tile) - OFS and then follow the removal steps from PCIe Attach F-Series (P-Tile/E-Tile) - OFS. The second set of instructions are for removing the HPS, which is not present in the mem_ss ip, but the steps for removing the two North banks are the same. I attached my preset for your reference.
3. Configure PCIe for Gen4 1x16 by specifying pcie_gen = 4 under [settings] in pcie_host_1pf_1vf.ofss. I attached my ofss for your reference.
4. (Optional) Refloorplan the PR region to recover resources that were used by the southern memory banks by following the steps here PCIe Attach I-Series (2xR-Tile, F-Tile) - OFS. I attached my pr_assignments.tcl for your reference.
5. Build the FIM with ./ofs-common/scripts/common/syn/build_top.sh -p --ofss tools/ofss_config/pcie/pcie_host_1pf_1vf.ofss iseries-dk:null_he_lb,null_he_hssi,null_he_mem,null_he_mem_tg,no_hssi work_iseries-dk_minimal_fim
6. Add a device model for AGIB027R29A1E1VB to $INTELFPGAOCLSDKROOT/share/models/dm. I attached mine for your reference.
7. Modify oneAPI ASP board_spec.xml for a 2x8 memory subsystem by following the instructions here: oneAPI Accelerator Support Package(ASP) Reference Manual - OFS. Make sure the number of memory banks is 2, the maximum theoretical bandwidth is 42656 ((1333MHz x 2 x 64 bits / 8 bits) x 2 banks), the Quartus project settings points to the correct device model, and the FPGA resources for kernel region matches your PR region size.  I attached my preset file for your reference. 
8. Set $OFS_ASP_ROOT appropriately and build the ASP by following the instructions here: oneAPI ASP Getting Started User Guide - OFS
9. Program the FIM following the instructions here: OFS for Agilex® 7 FPGA I-Series Development Kit (2xR-Tile,1xF-Tile) - OFS. Do not skip the sudo pci_device <PCIe BDF> unplug step, otherwise your PCIe link speed may be downgraded. 
10. Initialize the board and run aocl diagnose acl0 following oneAPI ASP Getting Started User Guide - OFS

I am a student unaffiliated with Altera. Let me know if this works for you.

Best,
Jason
