New in this Release
Yocto
Yocto Update: Update to 4.0 (Kirkstone).
Virtualization Support: Yocto now supports containerization via Podman and Docker.
New Distro: A new Yocto distribution, ampliphy-rt, has been introduced. It integrates Linux with PREEMPT_RT patches for real-time performance.
Linux Kernel
Kernel Update: Update to Linux v6.1.
2D Accelerator: The Vivante GC320 2D accelerator now utilizes the mainline Etnaviv driver.
RPMSG_RPC Disabled: The CONFIG_RPMSG_RPC option is no longer enabled, which means H.264 decoding via the Ducati GStreamer plugin is no longer available.
U-Boot Bootloader
Bootloader Update: Update to U-Boot v2024.04
Known Issues
PHYTEC’s Qt demo is not running on Wayland anymore. The EGL support in the SGX GPU driver has issues with Wayland. Wayland can still be used for other applications then EGL. TI acknowledged to fix this problem in their 10.x SDK.
Software Versioning
The BSP-Yocto-Ampliphy-AM57x-PD24.1.0 software release is largely based off of Texas Instruments’s v09.02.00.009 Processor SDK Linux release and shares much of the same components and features.

Linux Device Tree Summary
This is a summary of how the device tree source files (.dts) and the various include files (.dtsi) are broken down in the kernel. These files describe the hardware in a hierarchical and modular way to the kernel, connecting device drivers to the interfaces brought out by the carrier board.
Hardware Target |
Device Tree File Descriptions |
Filename |
|---|---|---|
phyCORE-AM57x kit |
Default dts Build Target (includes the other’s below) |
am5728-phytec-pcm-948-40300111I.dts |
SOM (silicon-specific) - adds support and enables silicon-specific features |
am5728-phycore-som.dtsi |
|
Carrier Board - enables circuits supported by the SOM |
am57xx-pcm-948.dtsi |
If designing your own custom carrier board around the phyCORE-AM57x SOM, you will eventually define a custom device tree for your board that includes the .dtsi file for the SOM, which PHYTEC has provided for you. All the BSP changes custom for your application should eventually be consolidated into its own Meta Layer.
Supported Boot Sources
The phyCORE-AM57x allows to load a bootloader from different kind of sources.

Supported Interfaces
The following table outlines the validated interfaces of the default phyCORE-AM57x development kit.
Note
This table only outlines the key features of the phyCORE-AM57x PHYTEC has chosen to enable by default, which serves as a basis for customization in production designs. Unnecessary interfaces can be disabled and additional interfaces can be enabled when deploying the SOM on a custom carrier board. Other features of the phyCORE-AM57x may or may not be configurable depending on pin multiplexing conflicts, for more information review the phyCORE-AM57x schematic in tandem with the Processor Datasheet.
