- Integrates a blinky demo for the M4F Co-processor based on TI's MCU+ SDK.
 * Documentation explains how to build and deploy a custom firmware.
- New Yocto image `phytec-initramfs-image` to flash and boot a tiny initramfs-based Linux from
  the OSPI NOR Flash.
- New Yocto distro `ampliphy-rt` which enables Linux with PREEMPT_RT patches.
- New Yocto distro `ampliphy-rauc` for A/B system updates based on RAUC [2].
- Adds watchdog support by switching to Poky's watchdog.

**Linux Kernel**

- Adds 1.4 GHz Operating Performance Point (OPP).
- Watchdog is now enabled by default.
- New overlay for AC200 OLDI display.
- New overlay for AC209 OLDI display.
- Reduces the I2C bus frequency, which is routed to the Carrier-board, from 400 to 100 kHz.

**U-Boot Bootloader**

- More Boot Sources available
 * Boot via Ethernet (Eth0)
 * Load and run U-Boot via UART (X49)
* Support for loading U-Boot over USB with Snagboot [3]

- Additional SoM options supported
 * QSPI as alternative for OSPI NOR Flashes
