My guess is that there is something else written to the reboot log area. I believe the reboot log package asserts that it initializes successfully. Do you know what code is at the indicated address (0x1a393)? This would be the case if it has been a long time since you erased your device's flash. The flash map changed in an non-backwards-compatible way between 0.9.0 and 1.0.0-b1. > Also, should those be enabled by default in samples in first place? Yes, that is probably a good idea IMO.
