Highly Anticipated and/or Frequently Asked Questions

Common issues

  1. Shortly after the kernel loads, the console turns to garbage (also PCI Express devices fail to enumerate)

    This occurs when the device tree passed to the kernel has not been 'fixed up' by U-Boot. On the LS1088 the fixup process sets up clocks, IOMMU and PCIe streams and other runtime properties. These are dependent on what peripherals are installed, so cannot be statically set in the device tree.

    In our U-Boot configuration this is performed by the setup_distroboot_efi command before the main boot sequence:

    setup_distroboot_efi=sf read 0x80001000 0x580000 0x40000 &&
      fsl_mc lazyapply dpl 0x80001000;  sf read $fdt_addr_r 0x600000 0x40000 &&
      fdt addr $fdt_addr_r &&
      fdt resize 10000 &&
      fdt rm /soc/spi &&
      fdt boardsetup
    bootcmd=run setup_distroboot_efi; run distro_bootcmd

    Due to issues with stream ID's not being set correctly on successive fixup invocations, the fixup handler for the Ten64 board will only apply fixups once (e.g when 'fdt boardsetup' is called).

    If the device tree passed to the kernel is not the same as the fixed copy, the same situation will arise.

  2. When booting something using Kernel 5.1 or later the boot fails with IOMMU fault messages

    Add the arm-smmu.disable_bypass=n parameter to the kernel command line. This is a temporary fix and hopefully the need to do this will disappear in the near future.

    See the Distributions and Kernel page for more information.


  1. How do I change the default boot order in U-Boot (booting from USB or SD instead of NVMe etc.)

    Change the boot_targets environment variable in U-Boot:

    => print boot_targets
    boot_targets=nvme0 mmc0 usb0 openwrt_nand backstop scsi0
    => setenv boot_targets 'usb0 nvme0 mmc0 openwrt_nand backstop scsi0'
    => saveenv
    Saving Environment to SPI Flash... Erasing SPI flash...Writing to SPI flash...done

    If you wish to reset the order to the default, you can use 'env default boot_targets && saveenv' to do so.

  2. How can I use a U-Boot bootscript in front of/instead of EFI?

    Due to the IOMMU issue mentioned above, if you want to run a U-Boot script for boot, your script must result in a kernel or EFI handoff. If your script returns back to U-Boot, you will experience issues with the IOMMU workaround.

    You can hand off directly to EFI in a U-Boot script by ending with:

    echo "Booting from ${devtype} ${devnum}:${distro_bootpart}"
    load ${devtype} ${devnum}:${distro_bootpart} ${kernel_addr_r} efi/boot/bootaa64.efi bootefi ${kernel_addr_r} ${fdt_addr_r}

    Note that this behaviour may change in future firmware/U-Boot versions.


  1. Does FreeBSD (and related distributions, pfsense, FreeNAS etc) run on the Ten64?

    It does now! Thanks to the work of the FreeBSD community. See FreeBSD preview for Ten64 for more information.

  2. Are there any 'binary blobs' needed for hardware on the Ten64?

    Yes, the DPAA2 hardware (Ethernet ports and some crypto acceleration functions) require the "management complex" firmware to be loaded. This runs on a microcontroller code inside the LS1088 - not the Cortex-A53's.

    The management complex firmware is loaded by U-Boot, just before hitting the command prompt (or default bootcmd). We do NOT expect distributions to ship this as part of their firmware repository.

  3. How do I compile/add extra packages to OpenWrt and derived distributions? (without compiling OpenWrt from scratch)

    The best way is to use the OpenWrt SDK. You can find the SDK package for our OpenWrt builds on our archive server, usually named openwrt-sdk-arm64-efi_gcc-8.4.0_musl.Linux-x86_64.tar.xz or similar.

    If you think this package is useful for others as well, feel free to post a suggestion on our forum.

    You can also use the ImageBuilder to roll images with your own package combinations (both pre-built from our repository and your own ipk's).

Power and Mechanical

  1. What is the typical power consumption for a Ten64 unit?

    Typical consumption (measured with a lab power supply) is between 14-18W with RAM and SSD installed.

    RAM modules with many chips (16,32GB), wireless modules/modems and USB devices can increase the power draw, but we haven't seen more than 30W drawn in practice.

    The amperage rating (5A) on the Ten64 compliance label is reflective of the maximum draw the Ten64 power system has been designed to provide in a 'maxed-out' sitation with high power WiFi and Cellular cards installed.

    Traverse typically bundles a 50-60W power supply - the increased wattage is to ensure longevity and reliability of the power supply.

  2. Can Ten64 be rack mounted?

    Ten64 has been designed with rackmounting in mind. The enclosure is exactly 1U high, but a conversion kit has not been manufactured yet.

    Please contact us for more details.

  3. What are the DC power supply requirements?

    Ten64 uses a 12V DC external power supply unit, with 2.5mm barrel, center-positive.

    The connector needs to be around 12mm long. Some other 12V DC, 2.5mm supplies on the market have shorter connectors which will not work.

    For electrical safety, you must use a three-prong power supply where the Earth pin is connected to GND.
