Dual-use of a serial port: Mark originally asked about dynamically inhibiting u-boot's use of the serial port for normal use, but allowing u-boot to use it for development/debug, selected by a jumper: <http://article.gmane.org/gmane.comp.boot-loaders.u-boot/44640> Hardware starved software development. :-/ For completeness, the gmane thread for the patch is here: <http://thread.gmane.org/gmane.comp.boot-loaders.u-boot/44788> For what it is worth, I'm with Haavard - it seems useful. WRT the dangerous part - it's intended use is for debug, so presumably it will be the developer that locks himself out of the console and will have the tools to break back in. From that POV, it isn't any more dangerous than all the other ways a user/developer can brick a board (starting with erasing flash ;-).
