Hello, as part of a small hobby project I recently started looking into SPARC V9 boot process and implemented a simple first-stage bootloader. If anyone finds it interesting, I documented everything I learned so far on the following page: https://cryintothebluesky.blogspot.com/2025/10/sparc-v9-boot-process-part-1-bootblk.html If you find any errors, then let me know. Thanks.
