Here's the most obvious question in the world on this topic. Are capes hot-pluggable?
"capes" as in Beaglebone capes might not be due to the mechanical constraints you listed. "capes" as a concept of pluggable hardware might well be. here is a real world example of commercially available pluggable hardware add-ons on a Linux system back from 2008: http://en.wikipedia.org/wiki/Archos_Generation_6#Accessories depending on the add-on, different interfaces like GPIO, UART, USB, SPI using the same pins were used and there was no reboot needed to load a new hardware configuration or change the pinmux -- To unsubscribe from this list: send the line "unsubscribe devicetree" in the body of a message to majordomo-u79uwXL29TY76Z2rM5mHXA@public.gmane.org More majordomo info at http://vger.kernel.org/majordomo-info.html
