For user application encryption, the user application binary file length must be a multiple of
16 bytes.
Finally, as done in the UserApp example, the IDE configuration must be updated to:
1. Generate a UserApp.bin file
2. Include search path for linker common files
3. Call postbuilb.bat to generate UserApp.sfb and SBFU_UserApp.bin with the correct
slot identification (1/2/3)
4. Integrate se_interface_appli.o to access Secure Engine runtime services if any
Figure 36 shows how to update the linker file to verify this constraint.
