A little confused about /tftpboot and /home/workdir/filesys

Anyone can tell me  the difference between them?

Some instruction told me to use /tftpboot/uImage as the boot file

Some instruction leads to /home/workdir/filesys/uImage (not very sure).

Are they equivalient or coexisting components?

And if coexisting, what's the difference?

Not very clear about the build and boot of the Montavista OS with NFS. Maybe someone could help even with a successful development process.

    A tftp server typically uses the /tftpboot directory as the default location for the Linux kernel uImage.  So if you are tftp'ing the kernel to the target at boot time, then the uImage file needs to be in the /tftpboot directory.

    Tftp is just one of many ways that uImage can be obtained at boot-up.  It can also be in NAND flash or on an SD card.

    Here is a general description of the boot sequence where uImage exists on an SD card.

    The other directory that you mention above looks like one that would exist in the development environment.  The uImage file would probably have to be moved (either to /tftpboot or to an SD card) to be useful.

    Hope that helps.
