ecc problem on imx28

Hello all,

We are using imx28 for a project. We have 4GB MLC NAND and we use UBI fs. We created 6 mtd partitions.

20   MB for linux

256 MB for rootfs

256 MB for backup of rootfs

others are not important

We have encountered ecc problem. Sometimes rootfs becomes readonly, sometimes it couldn't be mounted. We are using Samsung K9LBG08U0D, it has (4K + 218)B blocks and supports 8 bit failure for ecc. But in gpmi_nfc_set_geometry() function (in gpmi-nfc-hal-common.c file), ecc_strength is set to 16 for 218 bytes oob. Is this difference important? Should I set ecc_strength to 8?

Thanks

Mehmet

Hi Mehmet

ecc settings are not important in your case, just for testing

you can replace NAND, may be it is just damaged.

Best regards

igor
