Ubifs mtd update problem

I am not a NAND expert, but in general, you cannot update the file system on the device which is currently mounted as the active filesystem. It is like you cannot format c: drive while Windows is running in normal mode.

Where did you get the instruction which you did above?

hi,

i get the instructions from the link http://processors.wiki.ti.com/index.php/UBIFS_Support.

 if i boot file system over network, i can use the commands to flash my ubifs file system successfully.

any other method to do the file system update?

Thanks and Regards

Hi,

If you boot from SD card, you'll be able to flash rootfs to Nand.

You can also flash ubifs file system from Uboot. Check the below wiki.

No matter what method you use, you are simply unable to update the root filesystem on the device currently mounted as root filesystem.

You have to boot from a device different from the one you are going to update, for example, from NFS, SD card, or a different NAND partition.
