New in this Release
Yocto
Yocto Update: Update to 6.0.3 (Wrynose)
TI Firmware Update: Update TI firmware to v12.01.02
Ethernet Names: Previously, ethernet interfaces had alternate names in the form of ethX. These alternate names have been removed and interfaces can only be referred to by endX names.
Partup: partup is now v4.0.0 (updated from v3.0.0)
Linux Kernel
Kernel Update: Update to v6.18.38 (tag: v6.18.38-12.01.00.05-phy6) based on TI SDK v12.01.00.05
TI SDK Update: Update to TI Processor SDK Linux v12.01.00.05.03, using the 12.01.00.05 component baseline
OLDI Overlays: OLDI device tree bindings have changed, so the contents of the OLDI overlays have been reworked. The overlay names and functionality are unchanged.
U-Boot Bootloader
Bootloader Update: Update to U-Boot v2026.01-12.01.00.05 (tag: v2026.01-12.01.00.05-phy7)
Issues Fixed
eMMC Backup Boot Mode: Fixed an issue where eMMC as a backup boot mode was not detected.
flashcp Command: Fixed an issue where OSPI reads would be corrupted immediately after writing.
Known Issues
CAN FD: CAN does not work at 125 kbit/s.
MIPI DSI Backlight: The backlight PWM polarity of the LCD282 display overlay is inverted, so the backlight is almost off at the default brightness. Brightness level 1 is the brightest. See Display for the workaround.
Software Versioning
The BSP-Yocto-Ampliphy-AM62Px-PD26.2.0 software release is largely based on Texas Instruments’ v12.01.00.05.03 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) and overlays (.dtso) 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-08137-ALPHA.A1 (Default Kit) |
Default Device Tree (includes the other .dtsi files below) |
k3-am62p5-phyboard-lynx.dts |
Processor .dtsi - This file adds general support for the AM62Px Processor from Texas Instruments |
k3-am62p.dtsi |
|
SOM .dtsi - This file adds support for your specific SOM’s population options |
k3-am62p-phycore-som.dtsi |
If designing your own custom carrier board around the phyCORE-AM62Px 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. Consolidate application-specific BSP changes in a separate meta-layer.
Supported Boot Sources
The phyCORE-AM62Px can load a bootloader from several sources.
