I have read many of the posts regarding memory expansion cards in this newsgroup and I've skimmed the VFS docs, but I need a little help with the bigger picture (i.e., I'm seeing too many trees and not the forest).
We developed an app with one pdb database (in C). Our customers ask us to support memory cards. It isn't clear to me if we need to support memory cards (i.e., pass in a number other than zero for the CardNo requested by several functions), or if we are to deal with copying the program and data from a expansion card to main memory, and then restore the pdb to the card when done. That seems like a lot of work for a program with a single database (can you imagine copying a program from drive E: to drive C: to run it, and then copying it back to drive E: when done? Seems like the OS, or launcher, should handle that). It also isn't clear to me if there is more than one type of card (i.e., can apps run from any cards, or must all of them be accessed via VFS; if so, then what is the CardNo required by the database functions?). As you can see, I'm looking for a higher level view before committing to the lower level coding. Thanks!!
