# LIN Stack LDF

Hi!

I'm trying to use the S32DS to create a new application project using the Lin Stack. However, I want to use a .ldf that I already have. When I try that, I get the following message:

After this, my only option left is to let the S32DS rewrite my .ldf as if it was blank, and try to recreate my ldf through the component inspector, configuring each signal and message.

Basically, as I understand, S32DS is working as follows: .ldf is configured in the component inspector, then it rewrites the .ldf, and then the corresponding code is generated.

Is there a way to make it work such that: existing .ldf is imported, then that .ldf is used to configure the component inpector, and then the corresponding code is generated?
