Hi, I'm currently using yaffs on a new linux embedded device, and I made my tests by simply implementing the write / read / erase / init methods, and setting it manualy in yaffs_internal_read_super. My question is : What is the advantage of writing a new mtd driver for a yaffs filesystem? (I don't plan to use another flash filesystem, and don't plan to use already existing mtd drivers). Regards, André
