New ContributorAGMF039 has 32GB of HBM. 16GB of HBM is on the same NoC as HPS. Is it possible for HPS to use this 16GB (or perhaps even 32GB) of HBM to be connected to its MPFE interface instead of DDR.
Is there any example design for the same?
Hi
Apologize for the late reply.
The HBM could not be connected through the MPFE other than AXI.

New ContributorThanks for the link, it contains some wonderful design examples, but unfortunately not what we need. Btw is it architecturally possible to have the HPS boot of the HBM instead of DDR via the MPFE? If so can someone guide us how we can possibly achieve this.
Regular ContributorHi chander,
There is no HBM reference guide for Agilex 7 HPS referring to Agilex 7 TRM.
The available guide for building bootloader only uses DDR in the booting system.

Thanks.

New ContributorThanks Aik Eu,
Should we then conclude that its not technically feasible to have the HPS access HBM via the MPFE?
Or should we conclude that while its possible , there are no examples or documentation for it ?

Regular ContributorHi
There are a few method of configuring the Agilex7 listed below:
The closes to your mentioned use case is to Configure over AVST. Where the Agilex7 is configured through the Avalon Stream by an Avalon Master.

Any update on this case?

New ContributorHi,
The query was regarding the HPS being able to access the HBM over the MPFE interface rather than the AXI interface. The HPS can only access a 4GB address space over the HPS-to-FPGA AXI interface, however via the MPFE it can access 16GB address space or more. The query was if HPS can access the HBM via MPFE.
