Hello Charles, I've read the NAND datasheet in deep, ad it seems that I can't use the NAND splitting the page in subchunks to emulate four 512 bytes pages. As it says (page 15): "NAND Flash memory array is programmed and read using page-based operations and is erased using block-based operations", I think I have to switch to yaffs2 and handle all of its flavors. Glad to have your opinion about it. Thanks and regards, Stefano --- Questa e-mail è stata controllata per individuare virus con Avast antivirus. https://www.avast.com/antivirus
