BSP-Yocto-Ampliphy-AM62Px-PD26.2.0

This document highlights the key features and support included in the BSP-Yocto-Ampliphy-AM62Px-PD26.2.0 software release for the phyCORE-AM62Px SOM and development kit.

Board Support Package Status
BSP Operating system	Linux
Release Status	Released
Release Date	2026-09-30
Repository	PHYTEC Public Repos
Binaries	BSP-Yocto-Ampliphy-AM62Px-PD26.2.0

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: Bump from TI Processor SDK v11.02.11 to v12.01.00.05
OLDI Overlays: OLDI device tree bindings have changed, so the contents of the OLDI overlays has 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-phy6)

Issues Fixed

eMMC Backup Boot Mode: Fixed an issue where eMMC as a backup bootmode 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 125KHz.
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 off of Texas Instruments’s v12.01.00.05 Processor SDK Linux release and shares much of the same components and features.

Part Number Summary

Hardware Summary
Part Number	Hardware Description	Configuration Details (SOC / LPDDR4 / eMMC / NOR / Ethernet PHY / RTC / Temperature)	PCB Version
PCM-081.A0	phyCORE-AM62Px SOM	AM62P5 / 4GB / 32GB eMMC / 64MB OSPI NOR / Yes / Yes / Industrial	1622.0
PBA-C-37.A0	phyBOARD-Lynx AM62Px (phyCORE-AM62Px Carrier Board)		1626.0

Kit Summary
Part Number	Yocto MACHINE	Hardware Description
KPB-08137-ALPHA.A1	phyboard-lynx-am62pxx-1	PCM-081.A0 + PBA-C-37.A0 (Default Kit)

Supported Builds

This release supports multiple builds for different kits, Yocto images and distribution. The follow table lists all supported builds. See Part Number Summary for an detailed explanation of Yocto Machines and associated hardware.

Supported Build Summary
Yocto MACHINE	Yocto Image	Yocto Distro	Description
phyboard-lynx-am62pxx-1	phytec-headless-image	ampliphy-vendor	Headless image with PHYTEC’s ampliPHY vendor distribution for the KPB-08137-ALPHA.A1 kit.

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.

Linux Device Tree Summary
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. All the BSP changes custom for your application should eventually be consolidated into its own Meta Layer.

Supported Boot Sources

The phyCORE-AM62Px allows to load a bootloader from different kind of sources.

Boot Source Summary
Boot Source	Status	Notes
SD-Card	Supported
eMMC	Supported
QSPI/OSPI-Nor Flash	Supported
Ethernet	Supported	Eth0 (X10)
USB/DFU	Supported	USB-C (X8)
