Hello,
I'm porting Android to imx51 target and I'm facing issues while
writing android file system to nand.
I've created a jffs2 file in which I've put the android file system:
mkdir ram
cp -Rfp android_freescale/out/target/product/imx51_BBG/root/* ram
cp -Rfp /android_freescale/out/target/product/imx51_BBG/system/ ram
cp -Rfp android_freescale/out/target/product/imx51_BBG/data/ ram
mkfs.jffs2 -n -r ram -e 128 -o rootfs.jffs2
cp rootfs.jffs2 /var/lib/tftboot
The u-boot configuration is:
MX51 U-Boot > mtdparts
device nand0 <nand0>, # parts = 4
#: name size offset
mask_flags
0: BOOT 0x00700000 0x00000000 0

I'm able to write u-boot and uImage to nand but I have a problem with

Does anyone see where the problem is?
I need help please!
Thanks
