Fixed In This Release

  • Kernel
    • Version: Migrated from 4.1.13 to 4.4.12
    • USB: USB2 OTG fails to transition from host to device mode: USB2 is configured for 'otg' mode by default. When the system turns on, it will properly be detected as a device when plugged into a host machine. Plug and un-plug events are detected. If a device is plugged in to the USB2 port, triggering host mode behavior from the system, it will remain in host mode until the next warm reset or cold boot.
    • DSP: Both DSP cores are disabled to allow audio to work properly. The DSP cores can be enabled for calculations if McASP audio is not required. Future SDK releases from TI will improve DSP acceleration.
    • Ethernet: SOMs populated with AM572x silicon revision 2.0, ethernet auto-negotiates but fails to acquire an IP from DHCP or communicate when provided a static IP. There are no issues with silicon revision 1.0 or 1.1.
  • Yocto

    • Package ltp-ddt fails to build with arago-core-tisdk-image. Workaround implemented in build to remove ltp-ddt.

Known Issues

PHYTEC Known Issues

  • Kernel
    • Power: VBUS_DET implementation prevents complete poweroff. USB2 uses the PMIC VBUS_DET circuit, and when VBUS is provided by the processor (USB2 in host mode), the USB2_VBUS signal connected to the PMIC generates a WAKE event. As a result, the PMIC powers the system back up as soon as the shutdown finishes.
    • Display: When HDMI and LCD-018 are both enabled in the DTS, the LCD-018 display does not output data properly. The workaround is to enable one or the other, and LCD-018 is currently the default.
  • Yocto
    • Package ccs6 fetch fails due to TI export approval requirement. Workaround is to download the package manually as noted in the quickstart
  • U-boot
    • Processor fan is not enabled in u-boot.
