Hi,
1.Agilex7 m-series does not provide a BSP. If I want to deploy llama on Agilex7, can I only generate the BSP through OFS customization?
Yes, you are correct. You will need to customize it.
2.In the RTL support provided by OFS, I did not find HBM. Is it necessary to generate it myself through Quartus Prime Pro?
You can generate OFS for M-series dev kit from " ./ofs-common/scripts/common/syn/build_top.sh --ofss tools/ofss_config/mseries-dk.ofss mseries-dk:flat work_mseries-dk". Please refer to https://github.com/OFS/ofs-agx7-pcie-attach for all the supported BSP
3.In the 3.example_architecture folder, no information about hbm is provided. I would like to know how to modify the arch file in order to use hbm?
The arch file does not need to make the changes as the you it is handle from the BSP. The performance will change when it is running through HBM compare to DDR.
Thanks.
