with OpenWrt there is a feature where you have a "protected" area in RAM which is not lost during reboot and used for having a crashlog safed over a reboot. ("crashlog.o") see e.g:https://dev.openwrt.org/browser/trunk/target/linux/generic/patches-4.4/930-crashlog.patch we have extended this for always keeping a good timestamp over reboot.
Eh, that's nice, but as much as it makes sense for a crash log - where the device is not powercycled - it's only a partial solution as far as the clock is concerned: keeping a reasonable clock value across accidental reboots is good, but...
ofcourse this does not work with a cold reboot.
... this. When the user powercycles the device, which hopefully happens an order of magnitude more often than an accidental reboot, another workaround still needs to be found. Thanks for the info, however. It's interesting. -- Laurent _______________________________________________ busybox mailing list busybox@busybox.net http://lists.busybox.net/mailman/listinfo/busybox
