IMX28 EVK boots from NAND only first time. Errors 0x80508002 on reset.

Hi,

I am working to get linux to boot from NAND device, but the board boots correctly only first time after flashing. On reset it gives an error code of 0x80508002. When I took a hexdump of the boot partition just after flashing and after first boot, I observed that FCB and DBBT blocks are corrupted by some UBI info. I don;t understand why is that happening. I have attached the hexdump of first 1MB of boot partition before and after first boot.

I am using a UBI rootfs image to be written on to the mtd1 partition using nandwrite utility througfh Mfgtool. Attached is the ucl.xml file.

following are the commands that i am using to create ubi image file of rootfs.

mkfs.ubifs -m 2048 -e 126976 -c 2048 -r ./rootfs.tmp -o rootfs.ubi.img

ubinize -p 128KiB -m 2048 -s 2048 -o ubi.img cfg.ini

contents of cfg.ini
-----------------------
[ubifs]
mode=ubi
image=./rootfs.ubi.img
vol_id = 0
vol_size =128MiB
vol_type=dynamic
vol_name=rootfs0

My kernel command line is

noinitrd console=ttyAM0,115200 ubi.mtd=1 root=ubi0:rootfs0 rootfstype=ubifs rw gpmi

My imx28EVK has Micron's MT29F2G08ABAEAWP which is 2GB capacity. I have created 3 partitions in it by modifying the gpmi-nfc-mil.c source.

mtd0 - 20MB -- boot partition
mtd1 - 256MB -- rootfs
mtd2 - rest of memory -- no specific use

I have attached the complete log of flashing and booting from NAND for reference. I could not make out what could be the issue. Does anyone have any clue on what's wrong with my procedure. Any help or clue would greatly help me.

 

Thanks

GP
