TMS320F280039C: Static library usage with live firmware update (LFU)

Part Number: TMS320F280039C

Dear Champs, 

I am asking this for our customers.

Our customers use static library like TI driverlib.

Now, if they need to change some of their static library say from V1.0 (in the old image) to V1.1 (in the new image) with LFU (live firmware update), how do they do?

1. Do they still need to change the codes on the static library manually first and include them in the new project when building?
2. Does below preserve/update affect it? I think this only applies to global/static variable.
3. Does below path to reference ELF executable for LFU affect it?
