mounting system partition in Android ICS

bilel drira

Hi all,

I am trying to enable booting using android bootimages in my board based on ti am335x.

I am booting my kernel using the boot.img file. But I have problem in mounting the system partition.

I generated the system.img with the flag TARGET_USERIMAGES_USE_EXT4 ommited. So I am supposing that the system.img fs type is yaffs2 that's why I am flashing it in uboot with nand write.yaffs command.

int init.rc file I added :

on fs

mount yaffs2 mtd@system /system

this commands returns : "init: command 'mount' r=-1".

Am I missing anything ?

can anyone explain me how to add a partition and mount it in android ?

Thank you !

Hi,

Are you trying to boot from NAND?

Please refer to below wiki for more details.

Hi Pankaj,

Thank you for your response. But What I am asking for is how to use yaffs filesystem with the NAND.

The link you sent is covering only ubifs.

I am trying to create a partition in uboot to use it with an Android system.

Hi Bilel,

We have not tried yaffs2 with Android DevKIt. We only support ubifs for NAND.

Thanks and Regards,
