Enabling HPS-FPGA bridges on Agilex 7

To add on to this. I am just configuring the device with the GHRD and have confirmed that the bridges are setup correctly in Quartus. However, when I open platform designer I do see a warning saying:

Warning: intel_agilex_hps_inst.bridges.axi_h2f: axi_h2f must be connected to a MM host or exported

I was wondering if this could be contributing to the issue or if the warning is benign.

Show your actual Platform Designer system and how you have the HPS connected up. As noted in the messages there, the bridges don't appear to be connected to anything on the FPGA side.

Oops, my apologies, I sent the wrong image the second time. Here are the rest of the connections:

The GHRD I am using can be generated by using the following commands from Agilex GSRD tutorial:

git clone -b QPDS24.2_REL_GSRD_PR https://github.com/altera-opensource/ghrd-socfpga

mv ghrd-socfpga/agilex_soc_devkit_ghrd .

rm -rf ghrd-socfpga

cd agilex_soc_devkit_ghrd

export BOARD_TYPE = "DK-DEV-AGF014E"

make scrub_clean_all

make generate_from_tcl

I got the same warnings even if I did not change the board type.

Those are just IP warnings saying you need to connect those interfaces in the system you use the HPS, and they are connected. You can safely ignore.

Hi,

That is good to know I can ignore those. Do you have any idea what could be causing the error:

"Failed to enable the HPS bridges, check bridges availability. Status 4."

during the u-boot process? Could it be an issue with the device tree? Do I need to specify the bridges there? I found the hps_bridges mentioned in the device tree inside the socfpga-linux kernel, but not inside the u-boot.

Thanks,

Jack

Hi

We sincerely apologize for the inconvenience caused by the delay in addressing your Forum queries.

We appreciate your patience and understanding, and we are committed to providing you with the best support possible.

Thank you for your understanding.

Back to your issue, have you tried out flashing the prebuilt binaries instead of building the binaries?

Just to confirm that the hardware is working.
