Embedded LUA script

[Matt Wood]

Hi all,

I'm implementing an embedded LUA script in a sw-description file. For testing I'm just using a script based on the example to dump the image table. What I need from the data is image version attribute but it is being returned as nil. Does anyone know why and how to fix this?

Thanks, Matt.

function getImageAttrs(image)
for k,l in pairs(image) do
swupdate.trace(\"image[\" .. tostring(k) .. \"] = \" .. tostring(l))
end
return true, image
end

images: ({
filename = "image-name-machine.squashfs";
type = "flash";
sha256 = "$swupdate_get_sha256(image-name-machine.squashfs)";
device = "/dev/mtd1";
name = "Application";
version = "1.0.0";
hook = "getImageAttrs"
install-if-higher = true;
/*installed-directly = true;*/
});

Disregard, it was user error.  The field was indeed empty!

Thanks, Matt.
