Hi.

It might also help to write the flash immediately, but not to power off after that, but to check for low voltage again.
Also: Why does the empeg shut itself down on low voltage? Saving the flash immediately is correct behaviour, but why the complete shutdown? If the power supply comes up again while writing the flash, the empeg could simply continue running. If the power doesn't come up again, the lack of power supply will shut the empeg down automatically, so why bother?
