Handoff Files Agilex V - Handoff Files Agilex V Hi, I am using Quartus 24.1 with the Agilex V device ( A5ED065BB32AE4SR0 ), and want to make some edits to the device tree so that I can blink some led's via linux cmd. My research so far has led me to read a lot's of rocketboard posts, posts in the forums here, and more. From what I can tell, after I conect the Platform Designer and generate HDL, then Compile in Quartus - I should be given a handoff/ folder with some files in it, and with this it should be possible to generate a preloader. Later I would then be able to edit the device tree for my the leds. If so - why is the only file/folder generated by this process referencing `handoff` the `hps_bootloader_handoff.bin` file? Many thanks! K Replies: Re: Handoff Files Agilex V Hi both Thank you very much for your reply! I found that both these resources were extremely useful. Many thanks, K Replies: Re: Handoff Files Agilex V Hello K In addition to Whitepau's note, below are some links to collaterals that can help guide you for your task. If you have Agilex 5 E-Series Premium Devkit GSRD, the GSRD guides you on using the GPIO LEDs located at https://altera-fpga.github.io/rel-25.1/embedded-designs/agilex-5/e-series/premium/gsrd/ug-gsrd-agx5e-premium/ If you have Agilex 5 E-Series Modular Devkit GSRD, the GSRD guides you on using the GPIO LEDs located at https://altera-fpga.github.io/rel-25.1/embedded-designs/agilex-5/e-series/modular/gsrd/ug-gsrd-agx5e-modular/ We also have a Agilex 5 Design Hub where it can guide you to the relevant collaterals that you need for your task.

The device tree already references GPIO LEDs, if you would like to access LEDs on a PIO IP in FPGA fabric, there should be some guidance on that too, since the GHRD already includes an LED PIO. linux-socfpga/arch/arm64/boot/dts/intel/socfpga_agilex5_socdk.dts at socfpga-6.6.51-lts · altera-fpga/linux-socfpga Which devkit are you using? Have you studied one of the GSRD tutorials? Here is the one for the Agilex™ 5 E-series premium devkit: GSRD User Guide - Altera FPGA Developer Site If relevant, can you please share any relevant source files? Finally, for Agilex™ 5, the handoff information is all embedded in your FPGA image file (.sof or .rbf), we don't have a preloader anymore like we did for Cyclone V. Please let me know if you have more questions!
