Warning

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 Build the BSP.

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.
