Error faced while executing on Agilex FPGA board....
Hi team, I have been implementing and trying to port python model on Agilex 7- FPGA I series - board I have successfully installed Open vino (2024.6) and FPGA AI suit (2025.3) in my host pc Using Openvino I am able to create IR files and compiled graphs using FPGA AI suit. My next step is I copied files into SD card and i am trying to run on FPGA. I am using below command to check performance of my Python model in FPGA... ./dla_benchmark -cm Performance.bin -d HETERO:FPGA -i ./input_bins -bin_data -niter 1000 - nthreads 4 -pin YES -pc -pcsort sort -plugins=./model_opt_4_snr_20_50_ds_5_805.xml -report_folder ./reports_pc -stream_output Please check the screenshot attached for the error... Request you to suggest me for the solution
AI Suite System Throughput Issue
When using AI Suite, we are seeing a significant gap between IP throughput and achieved system throughput on Agilex 5. I am using the following: Hardware: Agilex™ 5 FPGA and SoC E-Series Modular Development Kit (ES silicon) Software: Quartus Prime Pro + AI Suite 25.3.1 SD Image: agx5_soc_s2m coredla-image-agilex5_mk_a5e065bb32aes1.wic Architecture and Bitstream: AGX5_Performance Using MobileNetV2 (Open Model Zoo 2024.6.0) compiled using AGX5_Performance architecture gives the following results through dla_benchmark IP throughput per instance: ~151 FPS Estimated throughput (200 MHz): ~178 FPS System throughput: nireq=1 → 41 FPS nireq=4 → 54 FPS Why is there such a big delta between IP Performance and System Throughput and how can we improve the system throughput? For more details please see the append log showing the commands that I run to do the benchmark Any pointers or help would be highly appreciated.
