Introduction
Buildroot (https://buildroot.org/) is a simple, efficient, and easy-to-use tool for generating bootable images for Embedded Linux systems through cross-compilation. Due to this it is a popular alternative to the widely-used Yocto-based build system. Some key differentiators are that it is easy to configure most aspects of the target image including but not limited to adding, configuring, and removing packages all using a menu-based system and that the build system itself behind the scenes is Makefile-based and with this will be immediately familiar to many developers (as opposed to the complex scripting language and layered approach Yocto uses). All this is what makes Buildroot very approachable and suitable especially for embedded systems engineers moving from MCUs into the world of Linux-based MPUs.
Current State of Support for TI's AM6x Devices
TI is aware of the need for Buildroot support for AM6x devices and has started working with the Buildroot community in 2022 on an initial implementation for AM64 devices. This effort somewhat stalled around the end of 2022 but has since been picked up again. On June 15th 2023 an updated patch set ("PATCH v8") has been posted to the community mailing list (https://lists.buildroot.org/pipermail/buildroot/2023-June/668947.html) to continue the previous effort, adding AM64 and AM62 device support including graphics based on some prework that was published as part of this E2E FAQ here over the last few weeks. The most current patch set was posted on June 22nd 2023 ("PATCH v9") and is available at https://lore.kernel.org/buildroot/20230625193648.GA646621@scaer/T/.
The below screenshot demonstrates current upstream Buildroot with experimental AM64x support added showing the "menuconfig" screen which is used for package selection and overall image configuration purposes. The rest of this E2E FAQ discusses how to setup and use Buildroot to build bootable SD card images for AM64x as well as for AM62x devices.
Building Bootable SD Card Images for AM62x and AM64x (Experimental Support Only!)
Disclaimer: The officially recommended and TI-supported way of generating bootable Embedded Linux images for use on Sitara AM6x devices is using the Yocto-based Linux SDKs for the different AM6x devices available at https://www.ti.com/tool/PROCESSOR-SDK-AM62X, https://www.ti.com/tool/PROCESSOR-SDK-AM62A, and https://www.ti.com/tool/PROCESSOR-SDK-AM64X. The steps outlined here to get early access and enablement of AM6x on Buildroot are provided as-is and are intended for experimentation only.
Due the experimental nature of the AM6x support discussed here there are several limitations with the created image, including but not limited to the following:
- While the current solution supports booting on AM62x HS-FS and AM64x HS-FS devices by default, it does not yet support booting on AM62x HS-SE and AM64x HS-SE devices. The certificate/signing process needed to support AM62x/AM64x HS-SE silicon for proper/full authenticated boot flow has not been fully implemented yet. If support for HS-SE is needed, those steps will need to get added, modeled after the current AM62x/AM64x Linux SDK.
- Some SoC-specific features such as remote core firmware loading / messaging and low-power mode support are not fully implemented and or tested yet
Setting up the Build Environment
As with most aspects of Buildroot setting up the build environment is pretty straightforward, and usually only involves cloning the official Buildroot Git repository to a Linux machine. Due to the official Buildroot repository currently (as of May 2023) only containing incomplete support for AM64x and no support for AM62x, some additional patches will need to get applied manually before images for these devices can be build.
To make re-creating Buildroot support for AM62x and AM64x easier those patches are provided as part of a tarball attached to this E2E FAQ for convenience. Always use the latest/most current patch set available for experimentation and consult the Change Log table column for additional details.
Also while Buildroot itself supports a wide range of host systems the steps outlined in this section were specifically tested using Ubuntu 22.04. Note that Buildroot expects a few basic packages to be present on the host system, many of which should already be preinstalled on a typical Ubuntu 22.04 system however. Usually installing the 'build-essential' and 'libncurses-dev' (for using the menuconfig interface) additional packages should be most/all that's needed. Refer to the official Buildroot documentation for additional details: https://buildroot.org/downloads/manual/manual.html#requirement

Supported Boards and Build Configurations
The below table provides an overview of how to setup builds for different boards that are supported. Note that there are several revisions of the TI Starter Kit (SK) boards in circulation that differ in the device variant that is used, amongst other things, requiring the build environment to get setup slightly differently. For simplicity sake, the board revision letter suffix (e.g., 'B') is omitted from most of the discussion in this FAQ.
| TI Starter Kit SKU | Device Variant | TI_SECURE_DEV_PKG Environmental Variable |
HS-FS Support Patch |
Buildroot defconfig |
| SK-AM62 | AM625 GP | Not needed | Don't apply | am62x_sk_defconfig |
| SK-AM62B | AM625 HS-FS | Required | Required | am62x_sk_defconfig |
| SK-AM64 | AM6442 GP | Not needed | Don't apply | am64x_sk_defconfig |
| SK-AM64B | AM6442 HS-FS | Required | Required | am64x_sk_defconfig |
Building SD Card Images
After the basic build environment was setup there's nothing special really about using Buildroot and building images at this point, so all the steps outlined in the Buildroot quick start guide (https://buildroot.org/downloads/manual/manual.html#_buildroot_quick_start) apply as-is. Below log capture shows a typical session building an SD card image for the SK-AM64 board via am64x_sk_defconfig.
# NOTE: Skip this step if using patch set v9 or later
#
# Create a clone of the core-secdev-k3 repository which is needed to provide the
# signing scripts and keys for building for HS-FS silicon variants. Note when

To build an SD card image for use with the SK-AM62 board simply use a different defconfig file (am62x_sk_defconfig) to reflect the different target platform as shown below. All other setup and build steps apply the same way.

Testing Graphics Support on AM62x
While the latest patch set enables the driver needed to support graphics on AM62x through the ti-rogue-km and ti-rogue-um packages, it does not enable any framework or application-specific packages out of the box. If you want to experiment and experience the graphics support you can add the following Buildroot config options either by applying the patch shown below or by manually selecting the appropriate options through make menuconfig:

WIP: configs/am62x_sk_defconfig: enable Weston and Chocolate Doom
This is a development/test commit to enable and allow experimenting
with the following features:
===Weston===
$ mkdir /tmp/weston-runtime-dir
$ export XDG_RUNTIME_DIR=/tmp/weston-runtime-dir
$ weston --tty=1
...or when no keyboard is connected...
$ weston --tty=1 --continue-without-input
===Chocolate Doom===
$ chocolate-doom
Note: sound not working yet

Programming the SD Card Images
The generated SD card images are ready to be used to boot the SK-AM64 and SK-AM62 boards and can be written to an SD card using the 'dd' command as follows:
# Copy image to SD card. Make sure you use the proper output device for your # system, otherwise data loss may occur (use 'lsblk' to double-check) a0797059@ula0797059:~/git/buildroot (am6x-dev) $ sudo umount /dev/sdc? a0797059@ula0797059:~/git/buildroot (am6x-dev) $ sudo dd if=output/images/sdcard.img of=/dev/sdc bs=1M status=progress && sync 136+1 records in 136+1 records out 142606848 bytes (143 MB, 136 MiB) copied, 6.35363 s, 22.4 MB/s
Testing the SD Card Image on the SK-AM64 Board
The resulting boot log should look as follows:
