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 :ref:`display-62P` for the workaround. Software Versioning ------------------- The |local-release-name| software release is largely based off of |vendor|'s |local-ti-sdk-version| Processor SDK Linux release and shares much of the same components and features. .. list-table:: Software Versioning :widths: 50 50 50 :stub-columns: 1 * - Tested Build Environment - Ubuntu 26.04 - `Ubuntu 26.04 Release Downloads `_ * - Linux Kernel - |local-kernel-version| (tag: |local-kernel-tag|) - |local-kernel-repo| * - U-Boot Bootloader - |local-uboot-version| (tag: |local-uboot-tag|) - |local-uboot-repo| * - Yocto - |local-yocto-version| (tag: |local-yocto-tag|) - |local-yocto-repo| Part Number Summary ------------------- .. list-table:: Hardware Summary :widths: 25 25 25 25 :header-rows: 1 * - Part Number - Hardware Description - Configuration Details (SOC / LPDDR4 / eMMC / NOR / Ethernet PHY / RTC / Temperature) - PCB Version * - PCM-081.A0 - |product| 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 .. list-table:: Kit Summary :widths: 33 33 33 :header-rows: 1 * - Part Number - Yocto MACHINE - Hardware Description * - |local-default-kit| - 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. .. list-table:: Supported Build Summary :widths: 20 20 20 40 :header-rows: 1 * - 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 |local-default-kit| 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. .. list-table:: Linux Device Tree Summary :widths: 25 50 25 :header-rows: 1 * - Hardware Target - Device Tree File Descriptions - Filename * - |local-default-kit| **(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 |product| 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 |product| allows to load a bootloader from different kind of sources. .. list-table:: Boot Source Summary :widths: 25 25 50 :header-rows: 1 * - Boot Source - Status - Notes * - SD-Card - **Supported** - * - eMMC - **Supported** - * - QSPI/OSPI-Nor Flash - **Supported** - * - Ethernet - **Supported** - Eth0 (X10) * - USB/DFU - **Supported** - USB-C (X8) * - UART - **Supported** - Debug UART (X5) - Can't boot Linux via UART.
