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... USB0: Core Release: 2.93a scanning bus 0 for devices... 2 USB Device(s) found scanning usb for storage devices... 0 Storage Device(s) found SOCFPGA_CHAMELEON96 # usb tree USB device tree: 1 Hub (480 Mb/s, 0mA) | DWC OTG RootHub | +-2 Hub (480 Mb/s, 2mA) the linux kernel (4.1.33-ltsi-altera) is also able to detect the USB Hub as can be seen in these logs: [ 0.913203] ffb40000.usb supply vusb_d not found, using dummy regulator [ 0.919864] ffb40000.usb supply vusb_a not found, using dummy regulator [ 0.957196] dwc2 ffb40000.usb: EPs: 16, dedicated fifos, 8064 entries in SPRM [ 1.817295] dwc2 ffb40000.usb: DWC OTG Controller [ 1.822011] dwc2 ffb40000.usb: new USB bus registered, assigned bus number 1 [ 1.829076] dwc2 ffb40000.usb: irq 44, io mem 0x00000000 [ 1.834617] usb usb1: New USB device found, idVendor=1d6b, idProduct=0002 [ 1.841394] usb usb1: New USB device strings: Mfr=3, Product=2, SerialNumber1 [ 1.848596] usb usb1: Product: DWC OTG Controller [ 1.853282] usb usb1: Manufacturer: Linux 4.1.33-ltsi-altera-svn260 dwc2_hsog [ 1.860481] usb usb1: SerialNumber: ffb40000.usb [ 1.865670] hub 1-0:1.0: USB hub found [ 1.869457] hub 1-0:1.0: 1 port detected ...

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, Manuel

Agilex 5 HPS EMAC2 SWR bit in DMA_Mode Register Not Clearing
Hello, Following section 5.1.7 of the Agilex 5 Hard Processor System Technical Reference Manual, and based on what I found in U-Boot and Linux, I am writing an Ethernet driver that uses EMAC2 with an RGMII interface. I am currently stuck at the software reset using the SWR bit of the DMA_Mode register, as it remains set to 1. Our boot flow on the AXE5-Eagle board is ATF -> U-Boot -> our OS. We use the U-Boot from https://github.com/ArrowElectronics/u-boot-socfpga/tree/socfpga_v2025.07 with some adaptations to load our OS instead of Linux. When I read the DMA_Mode register before performing any EMAC setup in our OS, I already see the value set to 1. After bringing the PHY out of reset and setting the SWR bit again, it does not clear. I also tried putting the EMAC into reset using the per0modrst register, setting the System Manager tsn2 register to 1 again, and then bringing the EMAC out of reset. This did not help, and after resetting the EMAC I can no longer read PHY registers over MDIO. When I load Linux instead of our OS, I can see that the reset using the SWR bit works correctly, but I can’t find what is missing in my implementation. Any help would be greatly appreciated. Thanks, Sarah For additional context, I read the following values before putting the EMAC2 in reset: PHY ID1: 0x283 Main PLLGLOB: 35000103 Per PLLGLOB: 35000103 DMA_Mode: 00000001 SYSMGR_TSN2: 1 EMAC2_DWCXG_CORE_MAC_TX_CONF: 0 CLKMGR_PERPLL_EN: fffffff CLKMGR_PERPLL_BYPASS: 0 CLKMGR_PERPLL_EMACCTL: 0 CLKMGR_CTLGRP_EMACACTR: 10001 CLKMGR_CTLGRP_EMACPTPCTR: 0 CLKMGR_CTLGRP_EXTCNTRST: 0Arria 10 SoC Dev Kit Baremetal HPS examples issue & workflow
Hi, I recently acquired an Arria 10 SoC dev kit but I'm really struggling to run either the examples on embedded-software/bare-metal or the ones included in SoC EDS pro 20.1, trying to follow the instructions for both of them, they seem to rely on a old version of SoC EDS which included within ARM DS-5 and the toolchain, but now SoC EDS & ARM DS are separated and I cannot build the examples. With the new applications the flow for using this examples should remain the same? I mean: use Pogrammer to program the included .sof inside ghrd (or generate a updated one) -> open ARM-DS from SoC-EDS with environmental variables assigned and build with new toolchain arm-none-eabi -> run from ARM-DS (can i without license?) Seems like most of the tools used for running this examples have been discontinued (for example ) so at this point I don't know which workflow should I actually follow. PD: finally I was able to generate de application.axf from this example Altera-SoCFPGA-HardwareLib-16550-CV-GNU with an old toolchain but I don't know how to program it without a license, for now I don't want to debug anything, just do some simple tests printing by uart
Agilex 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?Agilex 5 HPS EMAC2 SWR bit in DMA_Mode Register Not Clearing
