When preparing your netboot image, you have to concatenate tini_400.tbin and slush_400.tbin (or your application) before running it through the netboot converter. Netboot will erase/program bank 47 only if bank 47 has to be reprogrammed. Since the slush_400.tbin does not have any information for the first 256 bytes (the commit area), bank 47 will only be reprogrammed if the application itself has changed, the commit area is ignored. > Further to my previous posting about not being able to netboot if the > flash contents were different, I've since found this to not be the > case.

Maybe the commit locks the flash block and the netboot ROM code > doesn't know to unlock it? Anyway, if I make sure that I call > disableNetworkRestore() before doing a netboot it seems to work every time. -- Robert Muchsel - Dallas Semiconductor - http://www.maxim-ic.com/TINI/ _______________________________________________ TINI mailing list TINI-6tN4nzCoH/[email protected] To UNSUBSCRIBE, edit your profile, or see list archives: http://lists.dalsemi.com/mailman/listinfo/tini
