Yocto Machine Configuration Table

This BSP release supports various configurations of the phyBOARD-Zeta i.MX7. You will need to know which Yocto machine configuration corresponds to your kit in order to build the appropriate BSP. By default, only the standard kit configurations are shown in the table. If you have a different kit, use the filters below to search by Kit Part Number or SOM. The U-Boot defconfig and kernel device tree file names are important when creating custom U-Boot and kernel images outside of Yocto development.

Oops, it seems that you need to place a table or a macro generating a table within the Table Filter macro.

The table is being loaded. Please wait for a bit ...

BSP Features

The following table lists the interfaces available from the phyCORE-iMX7 SOM. 

  • Implemented - driver support exists in the kernel. 
  • Tested  - the interface has been configured in the device tree and was tested by PHYTEC 
  • Status in Device Tree - the corresponding device tree nodes are enabled in the device tree. See Linux Device Tree Summary for more information.

    The "Status in Device Tree" column is specifically for the standard phyBOARD-Zeta kit (machine configuration imx7d-phyboard-zeta-001).

    Please look at the dts file corresponding to your machine configuration for differences.

New in this Release


Changes made in Previous Releases

  • PD18.1.0
    • Yocto
      • Version: Ported to Yocto version 2.2 Morty
      • Yocto Image: supported image name changed from "fsl-image-gui" to "fsl-image-validation-imx". 
      • The image type is the same, just the naming has been changed by NXP. Note that the image name "fsl-image-gui" is still functional but simply uses the recipe for fsl-image-validation-imx.
    • Linux
      • Version: Migrated from Linux Kernel v4.1.15 to v4.9.11
      • Devicetree
        • imx7s.dtsi: Updated DTS structure to use separate processor dtsi for i.MX7 Solo, imx7s.dtsi. The i.MX7 Dual dtsi file, imx7d.dtsi, now includes the imx7s.dtsi and enables additional features.
        • Created separate carrier board dtsi files for i.MX7 Dual and Solo since the Solo does not support certain interfaces that are brought out on the carrier board. The new carrier board dtsi files are named "imx7s-pba-c-09.dtsi" and " imx7d-pba-c-09.dtsi".
    • U-Boot
      • Version: Migrated from v2016.03 to v2017.03
      • Devicetree: switched from board file to device tree.

Fixed in this Release


  • Linux: Update wdog property to fix reboot issue
    • Outdated device tree property was causing reboot not to function reliably with PD18.1.0.

    • Link to commit

Changes made in Previous Releases

  • PD18.1.0
    • Linux: imx7s-phyboard-zeta-002: reduce the size of CMA allocated on boot. Due to performance issues with the 4.9 kernel upgrade, less memory has been allocated to CMA so that more is available for the rest of the system.

Not Tested

  • PEB-WLBT-03
    • Driver support for Laird Sterling LWB has not been tested with Linux v4.9.11
  • Booting via network
  • Qt5 - NXP includes "fsl-image-qt5" Yocto Image in the BSP but it is meant for i.MX SoCs with hardware graphics, and is not supported by NXP or PHYTEC for the i.MX7D.

Known Issues

PHYTEC Known Issues

  • Ethernet:
    • iperf3 is included with the Morty Yocto BSP. With UDP, this command reports much lower bandwidth than expected when compared with iperf command.
  • eMMC:

    • Flashing with U-Boot: 
      • fsl-image-validation-imx-imx7d-phyboard-zeta-001.sdcard image is too large to be loaded into memory (1GB) from u-boot.
      • Workaround: Partition and flash eMMC from Linux instead. See Quickstart for instructions.
    • HS400 warnings/errors: configure eMMC to run at maximum 100MHz as a work around. See commit b8f6c1b7780 for more information.
  • Linux IMX Busfreq driver:
    • Driver disabled by default due to impaired UART console functionality when the system is idle (Low frequency setpoint).
    • For dynamic bus frequency scaling and improved power consumption, the busfreq driver can be enabled in the device tree by removing the "fsl,freq_scaling_disabled" property in imx7-phycore-som.dtsi. It can also be controlled in Linux sysfs: 

      echo 1 > /sys/bus/platform/drivers/imx_busfreq/soc\:busfreq/enable 
  • NAND:
    • 256MB NAND is too small to flash fsl-image-validation-imx filesystem. Booting from NAND was tested with core-image-minimal Yocto image, which is included with release binaries.

NXP Known Issues

See i.MX Linux Release Notes from NXP in  L4.9.11_1.0.0 BSP Documentation
