BSP-Yocto-Ampliphy-AM64x-PD23.2.0

New in this Release

Yocto

  • MACHINE= phyboard-electra-am64xx-2 for TI’s High Security-Field Securable (HS-FS) SoCs.

    • HS-FS variant phyCORE-AM64x SOMs are now the default SOM configuration shipping in Development kits.

  • UART boot source now available.

  • Inline ECC support is now available and enabled by default.

  • Virtualization support with Podman/Docker

Linux Kernel

  • TSN support for Ethernet.

  • New device tree overlay references for disabling optional population options of the SOM.

  • Watchdog support

  • GPIO FAN with pre-set thermal zone

  • ADC channels are configured correctly

  • RPMSG reserved memory regions enabled by default (previously enabled by device tree overlay)

U-Boot Bootloader

  • EEPROM Hardware introspection enabled for identifying Ethernet PHY, SPI-NOR Flash, and RTC population options

  • USB Host support

Software Versioning

The BSP-Yocto-Ampliphy-AM64x-PD23.2.0 software release is largely based off of Texas Instruments’s v09.00.00.007 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.

If designing your own custom carrier board around the phyCORE-AM64x 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 Interfaces

The following table outlines the validated interfaces of the default phyCORE-AM64x development kit.

Note

This table only outlines the key features of the phyCORE-AM64x 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 phyCORE-AM64x may or may not be configurable depending on pin multiplexing conflicts, for more information review the phyCORE-AM64x schematic in tandem with the Processor Datasheet.
