Re: [Ltib] Re: Ltib Digest, Vol 22, Issue 3

[Stuart Hughes]

Hi Henry,

>From the output Manjula sent I was guessing that he'd enabled ramdisk
output.  This is done by running "./ltib --configure" and selecting:

--- Target Image Generation / Options
    Target image: (ext2.gz ramdisk)  --->

If it is set to:
    Target image: (NFS only)  --->

You don't get a ramdisk and so "./ltib -D" won't show anything.

Note also LTIB can build jffs2 and other images.  Exactly how you get
these onto the target depends on which one it is and which bootloader
etc it is running.

Regards, Stuart
