New In This Release

  • Yocto
    • SDK: Ported to TI's Processor SDK v03.02.00.05
  • Kernel
    • Version: Migrated from Linux Kernel v4.4.12 to v4.4.32
    • PCIe: x2 lane support
    • Parallel Camera: Support added for VIN3 interface. Enabled and tested with VM-009-M12.
    • QSPI
      • Support added for QSPI1
      • QSPI NOR (N25Q128A) using QSPI1_CS2 is tested and enabled (see Known Issues)
    • MCSPI: Support added for SPI1. Enabled and tested using X_SPI1_nCS0 on connector X28 (Expansion Connector).
  • U-Boot
    • SD Card
      • U-Boot will always boot the kernel and rootfs from SD card, when present.
      • The U-Boot environment is strictly stored on the SD card, and cannot be saved without an SD card present.

Fixed In This Release

  • Kernel
    • GPIO: GPIO mapping now appears in contiguous order according to register assignments (see output of command: "cat /sys/kernel/debug/gpio"). Previous ordering was: GPIO1,2,3,4,6,7,8,5.
    • 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.

Known Issues

  • Kernel
    • Display: TI's Matrix-GUI demo only displays to either HDMI or LCD, not both. The workaround is to enable one or the other. LCD-018 is currently the default.
    • QSPI: Possible read failures on flash devices with HOLD function (Erratum i916). A software workaround has been implemented to limit QSPI to DIO-SPI mode. The hardware workaround is to disable internal pull-ups and add 10k pull-ups on X_QSPI1_D2 & X_QSPI1_D3.
      • For the software workaround, this commit also needs to be added to the source before building the .dtb. It is currently configured correctly when external pull-ups are installed.
