Hi all,
I am working on beaglebone black custom board with Android JB4.2(kernel version 3.2). Board also has SPI NOR for MLO, uboot.img and uImage . Board has been interfaced with 16 bit MT29F4G16ABADAWP for rootfs purpose. I am facing issue with nand rootfs bringup.
I enabled the pinmux in uboot bootloader and kernel.
Please have a look into the bootloader configuration file contents w.r.to nand

UBI image creation:
1. sudo tar -xjvf out/target/product/am335xevm/rootfs.tar.bz2 -C android_rootfs/
2. sudo mkfs.ubifs -m 2048 -e 126976 -c 1960 -r android_rootfs/ system_ubifs.img
3. ubinize -o rootfs-var-som-am33.ubi.img -m 2048 -p 128KiB -s 2048 -O 2048 ubinize.cfg
Please let me know with respect to 16 bit NAND configuration do we have to do the changes in the UBI image creations?????

I could able to erase and write the data to nand. Whne it is booting am getting ubifs errors.

Please let me know do we have to do any other code changes to support the 16 bit nand in uboot and kernel.
Thanks in advance.
