When Using EWF With A RAM Overlay, Can I Write To A Config File?

[John Branthoover]

Hello All,

I am looking at using a CF card (with wear leveling) in our embedded
application. I understand that the EWF can be setup to redirect all writes
to RAM. I assume that this keeps thing like swap files from wearing out the
CF card. My question is, can I still write a configuration file to the CF
card? This would done very infrequently.

Thank you for your time and have a nice day.

card?

Yes to non-protected partition. You should create two partitions.

Best regards,

Hello Slobodan,

Thank you for taking the time to answerer my question. I have
another question, will this second "non-protected partition" be protected
from un-requested writes from the XP OS?

Thanks in advance......

No.
But by default XP wont try to write to non boot partition. But this is up to
your configuration.
Probably only thing that will be written is dirty flag to FS.
But you can make RAW partition for config purposes, that XPE wont touch.
