Agilex 5 premium board - es version - boots with gibberish prompts
Hello dear community, I am trying to boot linux on the Altera Agilex 5 premium board - es version with the pre-built binaries. I followed the documentation still getting prompts in gibberish. Following is a detailed description of the procedure I used. My questions: 1. What am I doing wrong? 2. What should be my debugging flow steps? Detailed description of the procedure to demonstrate the issue: --------------------------------------------------------------------- In order to verify the Agilex 5 SoC premium baord is booting correctly, I used the pre-build binaries per the following instructions of this link: https://altera-fpga.github.io/rel-25.1.1/embedded-designs/agilex-5/e-series/premium/gsrd/ug-gsrd- agx5e-premium/#configure-serial-console I followed the paragraphs starting with the title " Exercising Prebuilt Binaries" This page instructs the user to download the pre-built binaries from this release: https://releases.rocketboards.org/2025.08/gsrd/agilex5_dk_a5e065bb32aes1_gsrd/ I followed the instructions of "Booting from SD card". The workstation is Windows 10 machine and the Terminal application is putty. Eventually, when booting the linux per these instruction, I see the first stage boot loader (u-boot spl) is prompting correct font, however the next booting stages are prompting gibberish. Attached is a screenshot (202604262215screenshot.jpg).
Agilex 5E ES Memory Performance Issues
Setup We observed significant performance issues during sequential memory reads in HPS. Target device is A5ED065BB32AE6SR0 from the premium dev kit using the GSRD Example. Sysbench was used to benchmark the memory performance. Test Results For comparison, we also performed the test on an STM32 system (Arm Dual Cortex-A7 800 MHz) and the host PC (Ryzen 7 CPU). Agilex 5E ES STM32MP157F Host PC, Ryzen 7 T0 (sequential read) 480 MiB/s 290 MB/s 78972 MiB/s T1 (sequential write) 4058 MiB/s 190 MB/s 44749 MiB/s T2 (random read) 67 MiB/s 373 MB/s 3461 MiB/s T3 (random write) 52 MiB/s 372 MB/s 3608 MiB/s The test cases where executed as follows: T0: sysbench --num-threads=1 --time=10 memory --memory-block-size=4MiB --memory-total-size=64GiB --memory-access-mode="seq" --memory-hugetlb=off --memory-oper=read run T1: sysbench --num-threads=1 --time=10 memory --memory-block-size=4MiB --memory-total-size=64GiB --memory-access-mode="seq" --memory-hugetlb=off --memory-oper=write run T2: sysbench --num-threads=1 --time=10 memory --memory-block-size=4MiB --memory-total-size=64GiB --memory-access-mode="rnd" --memory-hugetlb=off --memory-oper=read run T3: sysbench --num-threads=1 --time=10 memory --memory-block-size=4MiB --memory-total-size=64GiB --memory-access-mode="rnd" --memory-hugetlb=off --memory-oper=write run Observations The sequential read operation on the Agilex 5 is significantly (factor 10!) slower than the write operation. Especially when comparing to other systems where the sequential read achieves about a third more throughput. Sequential Read vs. Write: The sequential read operation on Agilex 5E ES is about 10x slower than the sequential write operation. On other systems, sequential read typically achieves about 30% higher throughput than write. We found 2 possible issues with the ES devices in the Errata: Degraded HPS EMIF performance with 2MB L3 Cache: https://docs.altera.com/r/docs/825514/current/agilextm-5-es-device-errata-and-user-guidelines/degraded-hps-emif-performance-with-2mb-l3-cache HPS EMIF read throughput less than target: https://docs.altera.com/r/docs/825514/current/agilextm-5-es-device-errata-and-user-guidelines/hps-emif-read-throughput-less-than-target The workaround for 1. is to change the L3-cache to a value different to 2MB. However, this did not improve the performance any way. For the second errata entry, there is no workaround. Question Is the "HPS EMIF read throughput less than target" errata entry the primary cause of the degraded sequential read performance? If confirmed, is this issue resolved in the series Agilex 5 Devices, and what performance improvements can we expect?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 Pratap

Hi, According to: https://docs.altera.com/r/docs/814346/25.3.1/hard-processor-system-technical-reference-manual-agilextm-5-socs/clocks?tocId=6fOPkXT1Zba2VR6U1OeQXg It is possible to configure SD controller in SDR12 mode with 25Mhz sdclk for sdcard: The clock to the SD card is the controller clock divided by 2 in these cases, and by 1 in all other cases. I have problem to obtain this setup: In my setup clocks are set as follows: l4_mp_clk = 200MHz (NOC 400Mhz clk /2) softphydiv is 4 so: clk_phy = clk_ctrl = 50Mhz (l4_mp_clk / 4) So controller frequency is 50Mhz. How to configure the SDMMC or COMBOPHY to divide controller clk by 2 for SDR12 mode? I don't see such option in register list: https://www.intel.com/content/www/us/en/content-details/775831/agilex-5-hps-register-map.html and u-boot drivers and devicetreee examples either. https://github.com/altera-fpga/u-boot-socfpga/tree/socfpga_v2025.10 sdhc_cadence, combophy drivers and dts examples in arch/arm/dts How to do this for uboot sd/combophy Cadence driver? With sd-uhs-sdr12 parameter for mmc node I still see 50Mhz on the sd clk pin from HPS to SD card. Marcin Z.Cyclone5 SoC: U-Boot not detecting USB-HUB
Hello there, I'm working on a design on top of a Chameleon96 Board (CycloneV based), featuring a USB OTG Chip USB3300, and connected to it an USB 2513B Hub. My issue is that neither U-Boot or Linux are able to detect the USB Hub connected to the USB3300. This used to work with older U-Boot versions and are still working on my board, but I was not able to reproduce such behavior with up-to-date versions (cloned from https://github.com/altera-fpga/u-boot-socfpga and https://github.com/altera-fpga/linux-socfpga). The Chameleon96 has two GPIO pins to control the reset of the mentioned USB chips, with a fixed configuration on the USB 2513B (the I2C interface is not exposed). With my version (U-Boot 2025.07-gd4f268660a70-dirty and Linux 6.12.33-g3234b1ed8956), the USB OTG is detected and the hub registered with logs like the following: [ 0.883275] dwc2 ffb40000.usb: supply vusb_d not found, using dummy regulator [ 0.890619] dwc2 ffb40000.usb: supply vusb_a not found, using dummy regulator [ 0.898034] dwc2 ffb40000.usb: Configuration mismatch. dr_mode forced to host [ 0.905721] dwc2 ffb40000.usb: DWC OTG Controller [ 0.910454] dwc2 ffb40000.usb: new USB bus registered, assigned bus number 1 [ 0.917571] dwc2 ffb40000.usb: irq 32, io mem 0xffb40000 [ 0.923324] usb usb1: New USB device found, idVendor=1d6b, idProduct=0002, b2 [ 0.931588] usb usb1: New USB device strings: Mfr=3, Product=2, SerialNumber1 [ 0.938800] usb usb1: Product: DWC OTG Controller [ 0.943509] usb usb1: Manufacturer: Linux 6.12.33-g3234b1ed8956 dwc2_hsotg [ 0.950362] usb usb1: SerialNumber: ffb40000.usb [ 0.955682] hub 1-0:1.0: USB hub found [ 0.959499] hub 1-0:1.0: 1 port detected but the connected USB hub never shows up. Similarly 'usb start' from the U-Boot prompt just shows something called U-Boot Root Hub: => usb start starting USB... USB DWC2 Bus usb@ffb40000: 1 USB Device(s) found scanning usb for storage devices... 0 Storage Device(s) found => usb tree USB device tree: 1 Hub (480 Mb/s, 0mA) U-Boot Root Hub Older u-boot versions (and linux) are able to detect the USB hub after 'usb start'. In this case, the root hub is named DWT OTC RootHub, and I don't know if this is just a change of naming somewhere or something wrong is also happening while detecting the USB3300 Hub: SOCFPGA_CHAMELEON96 # usb start (Re)start USB...

I've forked u-boot sources here: https://github.com/teiram/u-boot-socfpga/, using the socfpga_chameleon96_defconfig configuration. Could you please support me in order to troubleshoot what the issue might be? I tried to backport my changes to some different branches on u-boot-socpfga but got the same results or even worse (no boot at all). I also have sources for a working U-Boot but they are quite old and the configuration changed sensibly since. I think all the needed options are set. Cheers, ManuelAgilex 5 HPS TEE
Hi, Is Arm Trust Zone supported on HPS? If so is the implementation of TEE supported on Agilex 5? I've checked TF-A sources and it seems that BL2 on this platform loads only BL31 and BL33. How about BL32? Is there an OP-TEE support? If not, are there any plans to provide it in the nearest feature?
