Take a look at t. Is it valid? Does it point to a sensible init
function?

You need to configure the flashiodev. Look at
packages/io/flash/current/cdl/io_flash.cdl where is lists the
options. You need to tell is where in the flash the jffs2 filesystem
is, how long it is, or that it should use the redboot fis table to
find the image.

You can create a jffs2 filesystem in a file using mkfs.jffs2. Then
load it into flash. For the test fileio1, you can also use the test
image in the JFFS2 support directory, so long as you are on a little
endian system.
