Linux tools for unpacking and repacking YAFFS2 filesystem image:
DOWNLOAD YAFFS2TOOLS
Usage:
To unpack: Put your appfs.yaffs to the folder with unpacked files. Run unpack.sh. New appfs folder with unpacked files will appear.
To repack: Edit the appfs folder according to your needs (like replacing some voice audio files or UI text files). Run repack.sh and get the appfs_rep.yaffs file.
Compiled from sources from here and HiSilicon SDK.
