Hi I am running Linux 2.4.25, based on linux_2_4_devel from Denx, on a custom MPC5200 board. The boad has a TPS3705 chip for reset and watchdog. The chip also provides a powerfail interrupt when the supply voltage goes below a certain level, which is connected to IRQ0 on the MPC5200.
Capacitors on the supply provide me with some milliseconds to repond to power failure, which I would like to use to do as much cleanup as possible before power is totally gone. In particular, I am concerned with trying to prevent damage to filesystems. The board has Compact Flash and onboard flash which are used as filesystems. The board will be used as an industrial controller. Can anyone point me to examples of how this can be handled ? Can anyone share experience of a similar setup, which filesystems to select etc ?
