Oberon Security Drivers for nRF54L15

[grantrudd]

Hello,

Does the nrf_oberon library support the nRF54L series parts? In the technical documentation, it appears that M33 parts are supported:

https://docs.nordicsemi.com/bundle/ncs-latest/page/nrf/libraries/security/nrf_security/doc/drivers.html#nrf-oberon-driver

I am able to build my code (SDK/Toolchain version 2.9.0) for nRF52840 successfully using the nrf_oberon libraries, but the build fails for nRF54L15 targets with this error:

fatal error: ocrypto_aes_eax.h: No such file or directory
2 | #include <ocrypto_aes_eax.h>

If nrf_oberon does support the full range of M33 parts, are there any additional KConfigs necessary for the L15?

Thanks!

Hi Grant,

On nRf54L series, we are using CRACEN and the usage of nrf_oberon is not recommended. See here:https://docs.nordicsemi.com/bundle/ncs-latest/page/nrf/app_dev/device_guides/nrf54l/cryptography.html# and  https://docs.nordicsemi.com/bundle/ncs-latest/page/nrf/libraries/security/nrf_security/doc/drivers.html#cracen_driver 

We generally recommend the PSA Crypto API for cryptographic operations.

Regards,

Swathy
