Well, it is connected to the RSTI signal of the CPU, just as you would expect of a reset button. > I've only ever had a hard lockup once, where I couldn't even > reset the device with the reset button, and that was when (I think) the > battery reached a pretty low point and at the same time the hard drive was > being accessed. It is possible that the low power made the flash ROM enter a tristate mode. That happened to me once on an H300. Then I had to remove the battery, just like you described. > But yes, I do believe that the reset button isn't a hardware switch at all, > to me it looked just like a software switch just like the other buttons on > the device. If it was, how would you explain that the reset button works at all when running Rockbox? There is no code in Rockbox that handles a "software reset button". Trust me, it is connected to the CPU RSTI input. Linus Received on 2006-09-26 Page template was last modified "Tue Sep 7 00:00:02 2021" The Rockbox Crew -- Privacy Policy |
