· 4 pulledThis 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.
During my Chumby 8 kernel escapades, at one point I ran into a UART bug that affected multiple drivers, including the omap-serial driver.
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.
This led me to buy a BeagleBoard so I could verify the omap-serial bug on hardware.
