Known Issues PRE-RELEASE

  • 512 MiB: booting Linux with default environment not possible

    The addresses used in default environment and in BSP FIT image generation expect variants with 1 GiB or more RAM. Can be fixed manually.

  • NFS boot: The interface to be used for NFS boot (netdev) has inverted order, compared to u-boot and Linux. Device renaming in Linux happens after mounting rootfs.

  • U-Boot:

    • Not all USB sticks are detected properly.
    • Using usb reset in U-Boot will give a warning from Type-C port controller.
      The USB controller is configured as device only via device tree to support serial download use case.
    • boot from USB using uuu config displays misleading pinctrl / iomux warning.
      The UDC gadget driver warns not only for failed pinmux but also when no pinmux group is assigned in device tree.
