Drivers for two_stage governor have been removed. **U-Boot Bootloader** ^^^^^^^^^^^^^^^^^^^^^ * **Bootloader Update**: Update to U-Boot v2025.01 **Known Issues** ^^^^^^^^^^^^^^^^ * The kernel config ``CONFIG_BLK_DEV_NVME`` is not set. Thus automated tests for PCIe with attached NVMe fail. Software Versioning ------------------- The |local-release-name| software release is largely based off of |vendor|'s |vendor-fork| 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 22.04 - `Ubuntu 22.04 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: 50 50 75 50 :header-rows: 1 * - Part Number - Hardware Description - Configuration Details (DDR3 / DDR ECC / eMMC or NAND / QSPI NOR / Controller / EEPROM / Ethernet PHY / RTC / Temp) - PCB Version * - PCM-057-40300111I.A0 - phyCORE-AM57x SOM - 2GB (2 banks) / No / 8GB eMMC / No / AM5728 / Yes / Yes / Yes / Industrial - 1428.3 * - PCM-057-10306111I.A0 - - 1GB (1 bank) / No / 8GB eMMC / No / AM5729 / Yes / Yes / Yes / Industrial - 1428.5 * - PCM-057-50500111I.A1 - - 4GB (2 banks) / No / 32GB eMMC / No / AM5728 / Yes / Yes / Yes / Industrial - 1428.5 * - PCM-057-32302111I.A1 - - 2GB (1 banks) / Yes / 8GB eMMC / No / AM5749 / Yes / Yes / Yes / Industrial - 1428.5 .. list-table:: Kit Summary :widths: 25 25 25 25 :header-rows: 1 * - Part Number - Yocto MACHINE - Hardware Description - Notes * - |local-default-kit| - phycore-am57xx-1 - PCM-057.A3 + PCM-948 **(Default Kit)** - * - - phycore-am57xx-2 - PCM-057.A3 + PCM-948 - Headless only * - - phycore-am57xx-3 - PCM-057-40A00111I + PCM-948 - NAND Supported Builds ---------------- This release supports multiple builds for different kits, Yocto images and distribution.

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: 50 75 50 :header-rows: 1 * - Hardware Target - Device Tree File Descriptions - Filename * - phyCORE-AM57x kit - Default dts Build Target (includes the other's below) - am5728-phytec-pcm-948-40300111I.dts * - - SOM (silicon-specific) - adds support and enables silicon-specific features - am5728-phycore-som.dtsi * - - Carrier Board - enables circuits supported by the SOM - am57xx-pcm-948.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** - * - NAND - **Supported** - Supported Interfaces -------------------- The following table outlines the validated interfaces of the default |product| development kit. .. note:: This table only outlines the key features of the |product| PHYTEC has chosen to enable by default, which serves as a basis for customization in production designs. Unnecessary interfaces can be disabled and additional interfaces can be enabled when deploying the SOM on a custom carrier board. Other features of the |product| may or may not be configurable depending on pin multiplexing conflicts, for more information review the |product| schematic in tandem with the Processor Datasheet. .. list-table:: Supported Interfaces :widths: 25 50 :header-rows: 1 * - Interface - Status * - Debug UART - **Supported** * - Heartbeat & CPU activity LEDs - **Supported** * - GPIO buttons & LEDs - **Supported** * - eMMC - **Supported** * - NAND - **Supported** * - 2x CAN - **Supported** * - 2x Ethernet - **Supported** * - SD Card - **Supported** * - I2C EEPROM - **Supported** * - I2C RTC - **Supported** * - Parallel Camera - **Supported** * - SPI NOR FLash - **Supported** * - Watchdog - **Supported** * - DSP - Untested * - PRU-ICSSG - Untested * - GPU - **Supported** * - USB 2.0 + USB 3.0 - **Supported** * - HDMI - **Supported** * - LVDS - **Supported** * - WIFI - **Supported** * - Bluetooth - **Supported** * - PCIe - **Supported** * - SATA - **Supported** * - Audio - **Supported** .. note:: For technical support, please visit `PHYTEC's Support Portal `_!
