Hi, I've a s3c2410 board and I mount on NAND yaffs fs, with this operation: mkyaffs /dev/mtdN mount -t yaffs /dev/mtdblockN /mnt/yaffs with N: number of device. Is it corretct? For benchmarking NAND, I use bonnie++. When I use bonnie++ on NAND with YAFFS, it return this errors: can't putc() - disk full? nand_write_oob: Failed write verify, page 0x0001ffc0 nand_write_oob: Failed write verify, page 0x0001ffc1 But, when I'm writing on NAND I don't receive any errors. Why? Thanks.
