Intel FPGA AI suite input data type

Hello, I'm using Intel FPGA AI 2023.2 on ubuntu 20.04 host computer and trying to infer a custom CNN in a Intel Arria 10 SoC FPGA. I have followed Intel FPGA AI Suite SoC Design Example Guide and...

Hello @JohnT_Intel

There is no custom bitstream. The bitstream was compiled following the instructions in the Intel FPGA AI Suite SoC Design Example Guide, specifically in section "3.3.2 Building the FPGA Bitstreams." The compilation was performed using the dla_build_example_design.py script with the following parameters:

dla_build_example_design.py \
-ed 4_A10_S2M \
-n 1 \
-a
$COREDLA_ROOT/example_architectures/A10_Performance.arch \
--build \
--build-dir
$COREDLA_WORK/a10_perf_bitstream \
--output-dir $COREDLA_WORK/a10_perf_bitstream

I am a bit confused about your question because all the information I provided in the previous message is related to the compiled graph process, which, as far as I understand, is not dependent on the bitstream. From my understanding, the common factor between the compiled graph and the bitstream is the architecture file, which is A10_Performance.arch. And the input is detected as U8 with the .bin compiled graph file.
