Hi
My project uses an external NAND flash for image storage.
The flash is working but I now need to contend with bad blocks, error
correction and wear levelling.
Has anyone written their own 'simple flash file system'?
or has any tips, suggestions or can point me in the right direction....
thanks

Dear,
ECC code for 512 byte paged NAND from NXP web-site is working well
(although a bit difficult to understand in the first approach), I'm
currently using it. I've written my own "simply flash file system",
but It's rather very specific for our application, and it was about
two weeks work (although I don't handle files and I don't allow to
update data after the logical to physical block indices are written).
Regards
Herbert
