BSP-Yocto-Ampliphy-AM67x-ALPHA1

New in this Release

This is the first alpha release for the phyCORE-AM67x. The following interfaces are currently working:

  • SD-Card

  • eMMC

  • RTC

  • EEPROM

  • I2C

  • Ethernet

  • USB 2.0

  • USB 3.0

  • PCIe

Known Issues

  • USB 3.0: If a USB 3.0-capable device is connected at boot time, it may initialize in USB 2.0 mode instead of USB 3.0. Workaround: Unplug and replug the USB device after the system has fully booted to ensure USB 3.0 operation.

Software Versioning

The BSP-Yocto-Ampliphy-AM67x-ALPHA1 software release is largely based off of Texas Instruments’s v10.01.10 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.

Device Tree File Descriptions

Filename

KPB-08036-ALPHA.A0 (Default Kit)

Default Device Tree (includes the other .dtsi files below)

k3-am6754-phyboard-rigel.dts

Processor .dtsi - This file adds general support for the AM67x (Jacinto J722S) Processor from Texas Instruments

k3-j722s.dtsi

SOM .dtsi- This file adds support for your specific SOM’s population options

k3-am67-phycore-som.dtsi

If designing your own custom carrier board around the phyCORE-AM67x 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-AM67x allows to load a bootloader from different kind of sources.
