Hi,
I'm working with am35xx custom board.It has two 2GB ( 8bit )nand.
I'm using android filesystem( rowboat gingerbread ) to boot.Before nand concatenation, nand boot is working fine.
Then I concatenated nand.So that I got second nand is appended with 1st nand's filesystem partition like below.
Creating 5 MTD partitions on "am3517_lgvg_concat":
0x000000000000-0x000000080000 : "xloader-nand"
0x000000080000-0x000000400000 : "uboot-nand"
0x000000400000-0x000000480000 : "params-nand"
0x000000480000-0x000000e80000 : "linux-nand"
0x000000e80000-0x000040000000 : "File-System"
After this, I wrote filesystem into nand's mtd4 partition by following commands.
flash_erase /dev/mtd/mtd4 0 8076
mkdir /mnt/nand
mount -o rw -t yaffs2 /dev/block/mtdblock4 /mnt/nand
busybox tar xvf rootfs.tar -C /mnt/nand
sync
umount /mnt/nand
NAND bootargs:
setenv bootargs mem=256M console=ttyO2,115200n8 androidboot.console=ttyO2 root=/dev/mtdblock4 rw rootfstype=yaffs2 init=/init vram=32M omapfb.vram=0:16M
mmc init;fatload mmc 0 0x82000000 uImage;bootm 0x82000000
For first nand boot, no issues.But if I boot once again with the same bootargs, it is not booting.
It is giving error as
Failed to execute /init. Attempting defaults...
Kernel panic - not syncing: No init found. Try passing init= option to kernel.
After that no data are there in nand particular nand address.Everything got erased.
If I use jffs2 filesystem , it is not booting even for the first time.It is giving error as
D/dalvikvm( 949): DexOpt: --- BEGIN 'core.jar' (bootstrap=1) ---
D/dalvikvm( 1058): creating instr width table
E/dalvikvm( 1058): unable to mmap DEX cache: Invalid argument
E/dalvikvm( 1058): Optimization failed
W/dalvikvm( 949): DexOpt: --- END 'core.jar' --- status=0xff00, process failed
Please help me on this.
