How do I build Alpine Linux on BeagleBone Black?

Currently, I am exploring Embedded Linux and found out that Alpine is a good place to start with that. Thus, I tried to build Alpine on BeagleBone. I tried out multiple methods: 1. The Generic ARM setup 2. This neat repository https://github.com/BrianSidebotham/alpine-on-bbb I even tried to change the board up and try building it on STM32MP157D-DK1. I am really not sure where I am going with it. None of the lights on the board light up (SD Card Bootup) on either of devices.
