[1] Interface requires additional configuration, such as pinmuxing. It may be possible to change the software configuration to utilize this interface even if it is not being set in the board's default configuration. Please see NXP's i.MX7D Technical Reference Manual for more information on the various modes each pin can be muxed to.

Fixed In This Release

  • PCIe: 
    • Updated PCIe initialization process to toggle the device #PERST signal after the PCIE controller is reset. This solved issues with certain PCIe cards failing to initialize, such as Intel WiFi Link 3160.

New In This Release

  • Support for eMMC 5.0, HS400 mode

Not Tested

  • 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 Krogoth Yocto BSP. With UDP, this command reports much lower bandwidth than expected when compared with iperf command.
  • eMMC:
    • The following error messages may appear in Linux when running in HS400 mode. This is expected with high speed SD card protocols, and is not an actual error. This patch changes the message to debug level instead: https://patchwork.kernel.org/patch/8122111/

      mmcblk2: error -110 sending stop command, original cmd response 0x900, card status 0x400900
      mmcblk2: retrying because a re-tune was needed
    • Flashing with U-Boot: fsl-image-gui-imx7d-phyboard-zeta.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.
