I am using yaffs/direct.

I need to reduce the footprint in RAM a lot (maybe by not storing the
complete tnode-list in RAM and increasing pagesize etc.). Any suggestions
how to do that???

If you restart the system and you have a flash memory of 1GB, does the file
system then have to read the whole memory to create the original state???

I need as much information as possible to establish a good starting point
before trying to optimize.
