DFU target API integration

Question

Hi, 
 I am trying to integrate DFU into my application. Below is what I need to do. 
 I receive OTA application image over BLE (I can not use legacy DFU feature as we are using our own encryption for all the data exchange over BLE) and I need to write the application image. 
 I try using dfu_target APIs to do the work and I see undefined reference error for all the dfu_target APIs. 
 Please let me know what I need to do to include dfu_target APIs into my application. 
 Thank you in advance.

Hi again, 
 I checked this with our developers. 
 TF-M is another environment than Zephyr. Therefore you can not use Zephyrs libraries from the secure partition. You can not use dfu_target from the secure partition. 
 If you need to write files to the bootloader slots from the secure partition, you need to write this functionality yourself.
