Agilex 5E HPS and Linux
Hi. 1. Is there a simple method to run two Linux systems on HPS, i.e.: Linux 1 - 2xA55 and Linux 2 - 2xA76 with different sets of peripherals? 2. Is it possible to use one Ethernet port by these two Linux systems. 3. Is there a simple method for communication between these two Linux systems?
USB Device Issue on Cyclone V / HPS
Hello, Please find below a description of the USB issue we are experiencing with our Cyclone V / HPS board. To test our USB interface, we integrated the TinyUSB library into our existing firmware and enabled FreeRTOS support. Since the Cyclone V is not natively supported, I implemented the missing functions using Altera's hwlib, which we already use in our project (source file attached). The USB is used only in Device mode. I tested the following four configurations: Full-Speed with Slave mode Full-Speed with Simple DMA High-Speed with Slave mode High-Speed with Simple DMA The behavior is identical in all four cases: Connecting our board to a Windows or Linux host is correctly detected. The SETUP transaction is successfully received, and the host receives the device descriptor in response. When the IN transfer complete interrupt is triggered, the USB controller is configured to receive a zero-length packet on OUT0. However, the USB protocol analyzer shows that the device continuously responds with NAK to this packet. The host retries for approximately 5 seconds, but the device keeps responding with NAK. The register values immediately after configuring the reception of the OUT0 packet are: Gotgctl = 0xd00c0 Gintsts = 0x4000020 (PTxFEmp, NPTxFEmp) Gdfifocfg = 0x1f802000 Dctl = 0 Dcfg = 0x8100001 Dsts = 0x18702 Doepctl0 = 0x80008000 Doepint0 = 0 Doeptsiz0 = 0x80000 Grxfsiz = 0x50 After a few milliseconds, I observe that DOEPINT0.NAKINTRPT = 1, which seems to confirm that the device is sending NAKs. However, I do not understand why the OUT packet is not being accepted, since the receive FIFO is not full and both DCTL.GOUTNAKSTS = 0 and DOEPCTL0.NAKSTS = 0.

HPS ip configuration in platform designer for uart0 enabling in arria 10 soc
I have software tools Quartus prime pro 26.1, soc eds 20.1 and linaro baremetal tool chain. Now i configure the HPs ip for uart0 enabling but i am not sure wether it is correct or not, can you please conform it, and guide if there any changes required and if configuration is fine tell me the next steps to do.

S10 hps fpga2sdram bridge low speed
Hello, i have some problems I have a project with stratix 10 with hps I need to use ddr4 with hps, so I enabled 3 fpga2sdram bridges with 128 bit width Via u-boot smc configured and enabled them, but measured speed is not enough. When I use onle one bridge my speed is approximately 32 gbit/s (bridge and master frequency 350 MHz) But when I use all 3 bridges it becomes 20 gbit/s I use avmm bridge to connect to axi fpga2sdram bridge with 128 bits width, max pending writes 16, max burst size 128, use only write to bridge ECC in emif (hmc) is disabled I tried to use QoS for bridges, set them to bypass P.S. If i use the same board with firmware without hps, i get 130 gbit/s (with disabled hps) Quartus Pro 21.4 Any help would be useful!Need Step-by-Step Guide: Configuring Arria 10 HPS for UART0 Access (Tools & Workflow)
Hello Altera Community, I am starting a new project using the Intel/Altera Arria 10 SoC FPGA. My immediate goal is to successfully configure the Hard Processor System (HPS) side of the chip and enable HPS UART0 access so I can view the boot messages and interact via a serial console terminal. Since I am new to the Arria 10 HPS ecosystem, could someone provide a detailed, step-by-step workflow of the procedure? Specifically, I would appreciate guidance on: 1. Required Tools: Which exact software versions (Quartus Prime Pro, SoC EDS, Arm DS, etc.) are recommended for a stable Arria 10 HPS development pipeline? 2. Platform Designer (Qsys) Setup: What are the specific steps to route and configure UART0 pins, clocks, and DDR parameters inside Platform Designer? 3. Bootloader Generation: How do I correctly handle the hardware handoff files to generate the U-Boot/SPL bootloader using the SoC EDS utilities? 4. Target OS: I intend to use Bare-Metal . What are the final steps to write these images to a boot medium (like an SD card / QSPI flash) to verify that UART0 is transmitting successfully? If there are any updated Golden System Reference Designs (GSRD), specific user guides, or community tutorials that outline this exact UART0 baseline setup, please share the links. Thank you in advance for your time and guidance! Best regards, Team D&D ESSEN
Support Request to Debug Signal Tap Issue with SoC Based Design(GHRD) on Agilex-7 FPGA
Hi Altera Support Team, Greetings from Logic Fruit Technologies. This is Bhanu Pratap and I am working on the project in which we are using Agilex-7 SOC FPGA. Goal: Utilize Agiliex-HPS's capability on a Linux OS to control dynamic features of IP Cores at runtime. Problem Statement: We are facing an issue detecting SignalTap with SoC-based designs for runtime debugging while it's enabled and added from the Quartus project to generate the programming file. Brief Description: We are using Quartus 2025.1.1 and Altera's Agilex-7 Devkit(DKSIAAGI027FA: Agilex™ 7 FPGA I-Series Transceiver-SoC Development Kit -> 4x F-Tile, Rev C). We downloaded the base GHRD design from Altera's GitHub webpage for the corresponding Quartus version. We are following each step to test GHRD and build generation for the Linux OS. We are using HPS First booting mode, we generated the build without modification and tested it. It's working fine according to the GSRD user guide. We have added a custom AXI4 Slave based CSR module to the HSP Lightweight bus to test basic register read/write using Platform Designer. We regenerated the build and re-tested but we are not getting the expected results so we added SignalTap for debugging. Build is generated using the STP file, programmed, and the OS is booting but it's not detecting SignalTap. This looks more like a process gap. We seek your support to fix this issue. Note: If we use an FPGA design without HPS, we are able to add and detect SignalTap. Seeking for urgent support. Thanks Bhanu PratapRelease 26.1 PRO
