how to create a directory on the board?

Hi,

I have a stratix 1s10 with a uclinux. I'd like to create a directory (mkdir new_directory) but I don't have the permission. I think it's a question of right, but ...

I don't want to create my directory in Nios IDE and download the romfs.bin ; I want to create it directly on the board.

How can I do that in my board ?

Regards

John

    Hi John,

    The romfs is read-only ... you'll need to switch to a r/w file system

    to create directories, create/modify files, change attributes, etc.

    You might want to consider jffs2.

    Thanks a lot for your answer,

    But the only file I can download is romfs.bin. When I build my file-system, I don't have jffs2. How can I create this file ?

    Regards,

    Hi John,

    You'll need to enable jffs2 in the kernel configuration, then create your own

    jffs2 image using the mkfs.jffs2 utility. You can get the sources from:

    http://www.psyent.com/download (http://www.psyent.com/download)

    The sources at this site were ported for use under cygwin ... but you'd

    be doing yourself a favor (at least for the time being) to build the utility under

    linux -- as the cygwin version doesn't do a good job with some of the file

    attributes.
