phyCORE-i.MX7 SOMs with part number PCM-061-2110111C.A0 and later revisions are populated with eMMC 5.0. This device runs in HS400 mode and requires a patch to function with BSP release PD17.1.0. Please use BSP Release PD17.1.1 if you are using this SOM, or apply the following patch to the Linux kernel:

0001-MX7FLY-84-dts-imx7d-phycore-som-emmc-add-sd3-strobe-.patch

PCM-061.A0 - PCM-061.A4 and other SOM variants that do not use eMMC are not affected.

BSP Features

[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

• N/A

New In This Release

• Ported to NXP Release L4.1.15-2.0.1_ga  
  • Linux: 4.1.15
  • Yocto: Krogoth
  • U-boot: 2016.03
• PCIe supported and enabled in DTS. PCIe has been tested with the following devices:
  • Startech Mini-PCIe Gigabit Ethernet Network Adapter (ST1000SMPEX)
  • Intel WiFi Link 5300 Mini-PCIe Adapter

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:

    For further questions please contact support via the PHYTEC Support Portal.

  • 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.
• PCIe: Intel WiFi Link 3160 Mini-PCIe adapter fails to initialize.

NXP Known Issues

• See i.MX Linux Release Notes from NXP in  L4.1.15_2.0.0_LINUX_DOCS
