Hi,
This is when power is cut. Not by some guy or by anything that I manage.
Unfortunately - in this application, power must be cut fairly regularly.
The idea has developed a bit since my last email.
I am thinking of using a union file system for Angstrom with only the
home directory writeable located on a NAND chip.
I am be constantly saving data to a separate SD card with a FAT32 file
system - which I am worried will become corrupted when the hard reset
occurs.
What safeguards can I put in place to protect this?
Cheers,
Chris

What do you mean by hw-reset? Is it performed by some guy or you manage some
power switch?

I would like to install php5 and SQLite on SAM9261 board with linux
Angstrom. I'm really newbie and I have some problem with it. Should I use
ipkg? If not, how to do it?
Cheers,
PZ
