New in this Release
Yocto
TI Firmware Update: Bumped TI firmware to v11.02.11
Camera Support: Added phycam-setup package and udev rules for phyBOARD-Lyra camera
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.
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
AR0144 Camera Fixes: Fixed frame rate calculation, blanking control representation, and disallowed dynamic pixel correction changes while streaming
I2C Bus Frequency Fix: Corrected I2C bus frequency for cameras on phyBOARD-Lyra
U-Boot Bootloader
Bootloader Update: Update to U-Boot v2025.07 (tag: v2025.07-phy9)
RAUC Bootmeth: Merged upstream RAUC A/B bootmeth with memory handling fixes
Issues Fixed
Known Issues
Securiphy: There was a regression in the chain of trust while booting. When switching to u-boot standard boot we added an unsigned boot script, which is a violation of the chain of trust. This only applies to the securiphy distro.
Linux RT Latency: Real-time Linux can have worst-case latencies up to 600 microseconds under heavy memory load.
Flashcp Command Failures: Occasional failures during verification in flashcp.
Weston Startup Issues: Failure to start Weston when both HDMI and LVDS are active at boot.
Low-Power Mode MCU Issue: MCU-only low-power mode is non-functional when M4F firmware is loaded.
USB I/O errors: There may be I/O errors with /dev/sdb during the boot process from eMMC. However, no issues have been observed when reading from or writing to the drive after booting.
Software Versioning
The BSP-Yocto-Ampliphy-AM62x-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.

Note
Currently, we do not provide a mainline U-Boot version within our Yocto BSP.
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.

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.

Interface Overview
The following table contains all interfaces connected to the phyCORE-AM62x’s connectors and each status.
Note
For simplicity reasons interfaces located in the MCU and WAKEUP domains have a prefix. Interfaces located in the MAIN domain might have a main_ prefix but it was not added here.
