New ContributorAgilex 5 E-Series Premium DevKit GSRD - Configuring bitstream in runtime
Hi,
I'm using the Agilex 5 E-Series Premium DevKit with a HPS Enablement Board and successfully booted the GSRD Linux image as described in the user guide (Agilex 5 E-Series Premium Development Kit GSRD User Guide - Altera-FPGA Site).
Now, I also made a few changes in the respective Quartus project and wanted to know if I could boot up the board with the Linux image running and program the bitstream on top of it.
Basicly wanted to test out the changes I made (which are small and don't affect the HPS) without having to recompile the Linux image.
I did try to program the .sof I generated via the Quartus Programmer but got the following error:
Error(19192): File ../ref_design_output_files/ghrd_a5ed065bb32ae6sr0.sof is incomplete - HPS is present but bootloader information is missing.
So my questions are:
- Can I program a bitstream on top of the already running Linux image obtainned through the User Guide?
- If so, how can I do it?
Thank you,
Francisco Serôdio

Hi Francisco
Apologies for the delay in getting back as we're facing a number of backlog issues.
As for your question you can look at the linux overlay mechanism to configure run time
https://www.rocketboards.org/foswiki/Documentation/BuildingBootloaderForAgilex5
(Reconfiguring Core Fabric from Linux)
There is also similar case in forum that you can refer to https://community.intel.com/t5/Programmable-Devices/Agilex-5-configure-FPGA-from-running-linux-via-dt-overlay/m-p/1676186
Thanks
