Hi all, I'm working with a board where the power is turn on/off through a key as in a car. Is there any design pattern to afford that? It's the first time I have to manage a situation where the power can suddenly cut in anytime. Hardware guys are working to get "time" to do a clean shutdown (I turn the key but I still have the power) but any suggestions are welcome. However, I can't use a simply read-only filesystem (at least for root fs) because the board has got an sdcard that can be inserted (and then mounted in rw mode) anytime. Thanks.
