Develop ARM9 boards comfortably over NFS
Developing on the board itself is not quite handy. Any modification is done through a terminal window. NFS-mapping gives much more comfort.
While using NFS-mapping, the ARM9 Board will not boot localy any more, but will boot over the network using the NFS server of the development PC. Thus, one can modify the filesystem in a smart way, because the files are directly accessible. The files can be modified with the prefered tools.
Once finished, the update of the filesystem is done through an image:
(see here how this works).
