Hello,
Overview:
Currently we are using nRF9160 we are using mbedtls library for generating EC key based certificates (self-signed and CSR). Our code is built with TFM and application is non-secure. I need to understand following.
1. What is the role of TFM if application itself is in non-secure mode.
2. I want to remove mbedtls library and use PSA-crypto engine for certificate generation, parsing and signing how that can be possible.
Attaching the .config file after build for your reference. The aim to reduce the heap consumption done by mbedtls and optimize the code.
version used: nrf sdk version 2.7.0
Thanks,
Akshay
