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

UBIFS website

Setting up

  • host system: add mtd-utils uuid uuid-dev packages:
 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 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.
