BSP-Yocto-TISDK-AM65xx-ALPHA4

Software versions, supported interfaces, and new features.

Operating System	Linux
BSP Release Status	Released
Release Date	09 Dec 2020
Repository	PHYTEC Public Repos
Binaries	BSP-Yocto-TISDK-AM65xx-ALPHA4

This is an ALPHA BSP and is intended for evaluation purposes only. PHYTEC will not support development on ALPHA BSPs once a non-ALPHA release is made available.

This BSP provides a basis for development, deployment, and execution of Linux based applications on the phyCORE-AM65x System on Module (SOM). For detailed information on the various software components included in the release and how to use them, please refer to the BSP Development Guide.

Versioning

Software

Linux Kernel	5.4.74 (Based on TI SDK 07.01)	PHYTEC Source Repo
U-Boot	2020.01 (Based on TI SDK 07.01)	PHYTEC Source Repo

Yocto Machine Configuration Table

This BSP releases supports the phyCORE-AM65x Development Kit and also allows configuration options for different SOMs to be used with the kit carrier board (PCM-941). By default, only the standard kit configuration will be in the table. If you have a different SOM, use the filters below to search by the SOM part number. The U-Boot defconfig and kernel device tree file names are important when creating custom U-Boot and Linux kernel images outside of Yocto development, or modifying Yocto source for further use.

Linux Device Tree Summary

This is a summary of how the device tree files and the various includes are broken down, using the phyCORE-AM65x development kit as an example:

Hardware Target	Device Tree File Descriptions	Filename
phyCORE-AM65x Development Kit (SD enabled, WiFi disabled)	Default Build Target	k3-am65xx-phycore-kit.dts
	SOM (superset) - enables all SOM features	k3-am65xx-phycore-som.dtsi
