Agilex 7 can HPS use HBM instead of DDR to connect to MPFE - Agilex 7 can HPS use HBM instead of DDR to connect to MPFE AGMF039 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?

Regards Jingyang, Teh Replies: Re: Agilex 7 can HPS use HBM instead of DDR to connect to MPFE Hi Apologize for the late reply. The HBM could not be connected through the MPFE other than AXI. Regards Jingyang, Teh Replies: Re: Agilex 7 can HPS use HBM instead of DDR to connect to MPFE Hi, 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. regards Chander Replies: Re: Agilex 7 can HPS use HBM instead of DDR to connect to MPFE Hi Any update on this case? Regards Jingyang, Teh Replies: Re: Agilex 7 can HPS use HBM instead of DDR to connect to MPFE Hi There are a few method of configuring the Agilex7 listed below: Configuration over JTAG Configuration from QSPI Configuration over AVST Configuration via Protocol Remote System Update (RSU) https://www.intel.com/content/www/us/en/docs/programmable/683389/22-4/creating-the-configuration-files.html 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. Regards Jingyang, Teh Replies: Re: Agilex 7 can HPS use HBM instead of DDR to connect to MPFE Thanks 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 ? regards Chander Replies: Re: Agilex 7 can HPS use HBM instead of DDR to connect to MPFE Hi chander , I will close the thread if no further question. Thanks. Regards, Aik Eu Replies: Re: Agilex 7 can HPS use HBM instead of DDR to connect to MPFE Hi chander , There is no HBM reference guide for Agilex 7 HPS referring to Agilex 7 TRM. https://www.intel.com/content/www/us/en/docs/programmable/683567/23-1/hard-processor-system-technical-reference.html The available guide for building bootloader only uses DDR in the booting system. https://www.rocketboards.org/foswiki/Documentation/BuildingBootloaderAgilex7 Thanks. Regards, Aik Eu Replies: Re: Agilex 7 can HPS use HBM instead of DDR to connect to MPFE Thanks 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. Replies: Re: Agilex 7 can HPS use HBM instead of DDR to connect to MPFE Hi chander , I dont see there is an example design for that. Can search some of the example designs in the link below: https://www.intel.com/content/www/us/en/support/programmable/support-resources/design-examples/design-store.html Thanks. Regards, Aik Eu
