Hi,
I have i.mx28x evk. There is no nand on evk. I couldn't understand why. On a new project I have to use 8Gb nand(K9G8G08U0A). First of all I tried 1Gb nand(MT29F2G08AAD). There was no error. But I didn't try new partitions.
I have changed erase size of jffss image to 256K and page size 2K for my 8Gb nand.
Today I try 8Gb nand, and there are some errors. I wrote imx_ivk_linux.sb to /dev/mtd0 and rootfs.jffs to /dev/mtd1. I built from nand and mounted /dev/mtdblock1. At first boot there is no problem. If I reset board at new boot I get below errors
empty flash at 0x0000fffc ends at 0x00010000
mtd->read(0x74 bytes from 0x645f8c) returned ECC error
mtd->read(0x758 bytes from 0x6458a8) returned ECC error
JFFS2 notice: (2009) read_dnode: wrong data CRC in data node at 0x006458a8: read 0x605b1d36, calculated 0x73ae93ea.

mtd->read(0x184 bytes from 0x645e7c) returned ECC error
I need help. I am at starting of project and no time.
I have to create new partitions on 8Gb nand like below.
linux->32m
rootfs->256m
ekent->256m
adam->256m
storage-> -
I have added cmdlines on package list;
first:
noinitrd console=ttyAM0,115200 root=/dev/mmcblk0p3 rw rootwait ip=none gpmi mtdparts=gpmi-nfs.0:32m(kernel),256m(rootfs),256m(ekent),256m(adam),-(storage)
second:
noinitrd console=ttyAM0,115200 mtdparts=gpmi-nfs-main:32m(kernel),256m(rootfs),256m(ekent),256m(adam),-(storage) root=/dev/mtdblock1 rootfstype=jffs2 gpmi
I have tried with rootfs on sdcard(first cmdline) and on nand(second cmdline).
And checked mtd with "cat /proc/mtd" and saw only two partitions.
mtd0: 01400000 00040000 gpmi-nfc-0-boot
mtd1: 3ec00000 00040000 gpmi-nfc-general-use
I checked /proc/cmdline and it is right as I set.
It cannot be difficult but I don't know why I can't overcome.
Thanks.
Mehmet
