Thanks Hung, after following the tutorial, I was able to perform OTA DFU !

Hi Jerome,
You can have a look at the documentation here: https://infocenter.nordicsemi.com/topic/sdk_nrf5_v16.0.0/lib_crypto_backend_micro_ecc.html#lib_crypto_backend_micro_ecc_install
You should use the library .a file in nrf52hf_armgcc . SES use gcc as the compiler.

Hi Hung, thanks for your answer. I'm following the tutorial you mentionned.

Once I get there, I don't know which option I could use since I'm with SES and it doesn't seem to be a choice in micro-ecc.

Hi Jerome,
You would need to generate your own public & private key pair to use the bootloader. The default public key can only be used with the pre-generated images and only for the debug bootloader, not the release one.
I have a tutorial here that you can follow: https://devzone.nordicsemi.com/nordic/short-range-guides/b/software-development-kit/posts/getting-started-with-nordics-secure-dfu-bootloader
