New in this Release
This is the first release for the phyFLEX-AM62Px.
Known Issues
CAN FD: CAN does not work at a bitrate of 125 kbit/s.
Ethernet: Ethernet does not work in this release.
LEDs: The RGB LED (D31) on the phyFLEX-Libra AM62Px cannot be controlled from Linux because the PCA9633 LED driver (
CONFIG_LEDS_PCA963X) is not enabled in the kernel.
Software Versioning
The BSP-Yocto-Ampliphy-AM62Px-PD26.2.0 software release is largely based off of Texas Instruments’s v12.01.00.05 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 |
|---|---|---|
KPD-05033-S-PT001.A0 (Default Kit) |
Default Device Tree (includes the other .dtsi files below) |
k3-am62p5-phyflex-libra-rdk.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-phyflex-fpsc-g-som.dtsi |
If designing your own custom carrier board around the phyFLEX-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. All the BSP changes custom for your application should eventually be consolidated into its own Meta Layer.
Supported Boot Sources
The phyFLEX-AM62Px allows to load a bootloader from different kind of sources.
