AM29LV065D FLASH read, erase, program?

Normally this is done with mtd-utils: http://cvs.uclinux.org/cgi-bin/cvsweb.cgi/....old/mtd-utils/ (http://cvs.uclinux.org/cgi-bin/cvsweb.cgi/userland.old/mtd-utils/)

In your own applications if you use a JFFS2 filesystem, you can simply access the files with read, write, etc. system calls. If you don't use a filesystem, then you can directly access the device via the mtd device inodes (but your application is responsible for reading/writing the appropriate offsets in the flash).

You can also just access the flash directly through a pointer since there's no MMU. But this is probably not good practice unless you have some compelling reasons not to use mtd.
