Note
This is an ALPHA software release, it is possible that some features are not working or have stability issues. This release will NOT be supported after the first production-ready BSP release.
New in this Release
Yocto
Created a layer manifest based on TI’s Linux v08.03.00.005 Processor SDK Linux for AM62x
Added phyCORE-AM62x SOM and development kit support to meta-phytec
Linux Kernel
Added phyCORE-AM62x SOM and development kit support to v5.10.120 Linux kernel codebase sourced from TI’s v08.04.01.002 Processor SDK Linux for AM62x
U-Boot Bootloader
Added phyCORE-AM62x SOM and development kit support to the v2021.01 U-Boot bootloader codebase sourced from TI’s v08.03.00.005 Processor SDK Linux for AM62x
Software Versioning
The BSP-Yocto-TISDK-AM62x-ALPHA1 software release is mostly based off of TI’s v08.03.00.005 Processor SDK Linux release and shares much of the same components and features. The kernel however is pulled from the later release, v08.04.01.002.

PHYTEC Meta Layer
This BSP release supports the phyCORE-AM62x development kit and will eventually support configuration options for more SOM variants to be used with the development kit carrier board (PBA-C-24). Here is a summary of the Yocto Machine Configuration support introduced in the PHYTEC Meta Layer for this release:

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.

PCM-071.A0 + PBA-C-24.A1 (Default Kit) |
Default Device Tree (includes the other .dtsi files below) |
k3-am625-phyboard-lyra-rdk.dts |
SOM .dtsi- This file adds support for your specific SOM’s population options |
k3-am62-phycore-som.dtsi |
|
Carrier Board .dtsi - This file adds general support for the hardware interfaces featured on the development kit carrier board. |

If designing your own custom carrier board around the phyCORE-AM62x 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 Interfaces
The following table outlines the validated interfaces of the default phyCORE-AM62x development kit.
Note
This table only outlines the key features of the AM62x Processor PHYTEC has chosen to enable by default for the phyCORE-AM62x Development Kit, 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 AM62x Processor may or may not be configurable depending on pin multiplexing conflicts, for more information review the phyCORE-AM62x schematic in tandem with the Processor Datasheet.
