Hi,

instructions on how to build am AM335x image can be found in our Linux SDK Documentation, see https://software-dl.ti.com/processor-sdk-linux/esd/AM335X/09_01_00_001/exports/docs/linux/Overview_Building_the_SDK.html

The BeagleBone Black is one of the platforms supported by that SDK, see https://software-dl.ti.com/processor-sdk-linux/esd/AM335X/09_01_00_001/exports/docs/linux/Release_Specific_Supported_Platforms_and_Versions.html

Regards, Andreas

Starting from 9.x (6.1 kernel based SDK) you would need to use libgpiod instead of sysfs
