I am writing a MTD NAND (2K page) driver module for Linux 2.6.23.
My NAND hardware controller performs all the ECC control
under-the-hood. Although is has OOB bytes available there are some
L1.) Page data and OOB data must be written at the same time.
L2.) OOB data is limited to 16 bytes / page (of a 2k page).
I have some questions about the OOB requirements for MTD/JFFS2 combo.
Q1.) Does MTD/JFFS2 require the ability to read/write OOB bytes?
Or can the system be set up operate with no OOB available?
Q2.) Is it a requirement for OOB and non-OOB writes to happen independently?
thank you for you help,
