New In This Release


  •  Added support for machines:
    • phyboard-segin-imx6ul-2 (phyBOARD-Segin full featured)
    • phyboard-segin-imx6ul-3 (phyBOARD-Segin low cost)
    • phyboard-segin-imx6ul-4 (phyBOARD-Segin full featured with RS485)
  • Added new features:
    • Mainline kernel based on v4.12.4
    • Support for displays:
      • AC158 (7" capacitive)
      • AC156 (7" resistive)
      • AC103 (5.7" capacitive)
      • AC102 (4.3" capacitive)
      • AC167 (3.5" capacitive)
    • Resistive touch
    • Booting barebox from NAND
    • Support USB_Host in barebox
    • QT5 (5.7.1) support, QT5 Demo 1.1 working with limited functionality (see Known Issues)
    • RS485 support (kernel)
    • 2x Ethernet ports (kernel)
    • Support for Wireless LAN Module PEB-WLBT-01 (WiFi only, no Bluetooth)

Not Supported


  • Removed support for machine:
    • phyboard-segin-imx6ul-1

Known Issues


PHYTEC Known Issues

  • The 696 MHz operating point of the phyCORE-i.MX 6UL is not supported.

  • The DVFS pin to switch VDD_ARM_SOC from 1.4 V to 1.3 V on phyCORE-i.MX 6UL/6ULL is already included in the device tree but not yet supported in the kernel. But DVFS with internal LDOs is already supported.
  • When booting from MMC, sometimes (about 5 in 1000) barebox and kernel fail to attach the NAND devices.
  • ADC provides uncalibrated values.
  • Booting the root filesystem over NFS is not possible.
  • TFTP in kernel is slow, but UDP in general is not affected.
  • Multimedia page is removed from QT5 Demo.
  • QT5 Demo is only working correctly on the 7" displays, smaller displays need adaptation.
  • Starting and stopping the QT5 demo influences the consoleblank parameter.
  • When returning from suspend to RAM (mem or standby) the display might not work correctly.
  • Suspend to RAM (freeze) does not work correctly.
  • RS485 is only working correctly in raw mode (stty -F /dev/ttymxc4 raw echo -echoe -echok -echoctl -echoke).
  • The TiwiBLE chip sometimes requests a restart of the firmware which leads to a backtrace dump. The connection is reestablished afterwards and transfers continued.
