hi,

TI,

There are MT29F8G08ABABA on my 8148 board. It is ok of write and read operation. But after I write the filesystem into the nand flash,then boot up,it will happen the ecc error:

By the way,the  ecc mode is CONFIG_MTD_NAND_OMAP_ECC_BCH8_CODE_HW in the kernel.The kernel is from dvrrdk_kernel_int_branch branch.

here are the features of the MT29F8G08ABABA :

Features
• Open NAND Flash Interface (ONFI) 2.1-compliant1
• Single-level cell (SLC) technology
• Organization
– Page size x8: 4320 bytes (4096 + 224 bytes)
– Block size: 128 pages (512K +28 K bytes)
– Plane size: 2 planes x 1024 blocks per plane
– Device size: 8Gb: 2048 blocks

I saw the linux core nand user guide,it says that the driver is support the block-size = 128k | 256k,

any sultion or suggestion?
