This is a preliminary page dealing with the installation of UBIFS on the APF boards. UBIFS will replace JFFS2 file system on NAND based board because JFFS2 induces a big overhead when parsing, reading and writing on NAND devices UBISFS scalability
Introduction
Setting up
- host system: add uuid-dev packages (should be already installed as required to build the HEAD of Armadeus repository) :
sudo apt-get install uuid-dev
- buildroot: target filesystem -> ubifs root filesystem (0x1F800, 0x800, 2047)
- linux: file systems -> Miscellanous -> ubifs support and disable debugging !!
- linux: device driver -> mtd -> ubi unsorted block image -> Enable UBI (4096) and disable debugging !!
- uboot: setenv bootcmd run ubifsboot
- uboot: setenv download_rootfs tftpboot ${loadaddr} ${serverpath}${board_name}-rootfs.arm.ubifs
Additional informations
A new file 'ubinize.cfg' defining the ubi volumes is located in buildroot/target/device/armadeus/ this file contains the different UBI volumes of the UBI image:
[ubifs] mode=ubi vol_id=0 vol_type=dynamic vol_name=rootfs vol_alignment=1 vol_flags=autoresize
This file is processed by the ubinize utility after mkfs.ubifs.
