Because of the fast update possibility the file system on your board is always up-to-date.
2 steps to update the file system
The filesytem has to be installed beforhand:
(see the advantages using NFS).
Updating the Linux filesystem is done in two easy steps:
- Run a given script that creates an image based on the files of the filesystem. The image will be copied to a directory, to which the ARM9 board has access:
|
mkfs.jffs2 --root /nfs/ecpu1100 --output filesys.jffs2 -- pagesize=2048 --eraseblock=131072 --pad --little-endian -n cp filesys.jffs2 /tftpboot |
- While running a command in the boot-loader u-boot, the ARM9 board will get the image an will actualize its filesystem:
|
run update_rootfs |
