New in this Release
Yocto
TI Firmware Update: Bumped TI firmware to v11.02.11
Vulkan: Enabled Vulkan distro feature
partup: Updated to v3.0.0 with SPI-NOR flash layout configs
Serial Names: Serial interfaces now have predicable aliases in /dev/serial/by-label/ based on the device-tree node name. The behavior of /dev/ttyS devices has not been changed.
Ethernet Names: Ethernet interfaces now have predictable names with endX. Previous names with ethX are still supported as alternative names, but support will be removed in a future release.
Linux Kernel
Kernel Update: Update to v6.12.57 (tag: v6.12.57-11.02.11-phy6) based on TI SDK v11.02.11
TI SDK Update: Bump from TI Processor SDK v11.01.05 to v11.02.11
phyBOARD-Rigel Device Tree Updates: Updated compatible string, added vdd-supply to light sensor, renamed pinmux nodes
USB Role Switching: Added support for USB role switching on phyBOARD-Rigel
SPI0 Overlay: Added SPI0 overlay for phyBOARD-Rigel X37 connector
DDR Size Update: Update the DDR timings for the phyCORE-AM67x to use a 4GB module with an effective size of 4GB.
U-Boot Bootloader
Bootloader Update: Update to U-Boot v2025.01 (tag: v2025.01-11.02.11-phy6)
TI SDK Update: Bump from TI Processor SDK v11.01.05 to v11.02.11
Device Tree Sync: Synced U-Boot device trees with kernel v6.12.57-11.02.11
Issues Fixed
Known Issues
USB 0: usb0 works as a DFP (host) only on .1 carrierboards.
USB 1: usb1 is only capable of USB 2.0 on .1 carrierboards.
Audio: recording with the microphone does not work.
CAN FD: CAN does not work at 125KHz.
Software Versioning
The BSP-Yocto-Ampliphy-AM67x-PD25.1.1 software release is largely based off of Texas Instruments’s v11.02.11 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 |
|---|---|---|
KPB-08036-001.A0 (Default Kit) |
Default Device Tree (includes the other .dtsi files below) |
k3-am6754-phyboard-rigel.dts |
Processor .dtsi - This file adds general support for the AM67x (Jacinto J722S) Processor from Texas Instruments |
k3-j722s.dtsi |
|
SOM .dtsi- This file adds support for your specific SOM’s population options |
k3-am67-phycore-som.dtsi |
If designing your own custom carrier board around the phyCORE-AM67x 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-AM67x allows to load a bootloader from different kind of sources.
