This post is about the original OMAP3530 BeagleBoard from 2008. Yes, the one so old that it doesn’t even show up in the board list on BeagleBoard.org anymore. The BeagleBoard, not the BeagleBone. During my Chumby 8 kernel escapades, at one point I ran into a UART bug that affected multiple drivers, including the omap-serial driver. This led me to buy a BeagleBoard so I could verify the omap-serial bug on hardware.
After I figured out the bug with the UART driver, I realized that the OMAP3530 has support for booting from USB, so I decided to go off on a random tangent to get USB boot working. There was no problem I was trying to solve or anything like that. I just thought it would be a fun experiment (am I a masochist?). Little did I know, I would be getting myself into some tricky USB packet analysis.
