Hi, all
I run TI_Android_GingerBread_2_3 on my AM3517 board, our nand flash is MT29F2G16(NAND device: Manufacturer ID: 0x2c, Chip ID: 0xca (Micron )). I use readonly ubifs to holt android filesystem, and /data is mounted as yaffs2. My application have to insert data to sqlite database frequently and delete some data from database every 30minute.
My kernel ( Linux-2.6.37-g06ebbba-dirty) configs as bellow:
#
# Disk-On-Chip Device Drivers
#
# CONFIG_MTD_DOC2000 is not set
# CONFIG_MTD_DOC2001 is not set
# CONFIG_MTD_DOC2001PLUS is not set
CONFIG_MTD_NAND_IDS=y
CONFIG_MTD_NAND_ECC=y
# CONFIG_MTD_NAND_ECC_SMC is not set
CONFIG_MTD_NAND=y
# CONFIG_MTD_NAND_VERIFY_WRITE is not set
# CONFIG_MTD_SM_COMMON is not set
# CONFIG_MTD_NAND_MUSEUM_IDS is not set
# CONFIG_MTD_NAND_GPIO is not set

# CONFIG_MTD_NAND_NANDSIM is not set
# CONFIG_MTD_NAND_PLATFORM is not set
# CONFIG_MTD_ALAUDA is not set
# CONFIG_MTD_ONENAND is not set
I found data in nand have bit changed, this will direct to applicat cann't run or android system cann't run
