Crypto build error when using nRF7002EK in Zephyr 4.1

[Christoffer Brask]

Hi,

I receive the following build error: "../zephyr-project-v4.1.0/modules/crypto/mbedtls/include/mbedtls/check_config.h:96:2: error: #error "Unsupported partial support for ECC curves acceleration, see docs/driver-only-builds.md"

Target MCU: STM32H755 with BLE shield, but same happens when target is nRF5340.

Steps to reproduce

The easiest way to reproduce the build error without too many modifications:

1. Use peripheral_hr as sample project
2. In CMakeList add set(SHIELD nrf7002ek) or use the shield argument in west
3. In prj.conf add CONFIG_NETWORKING=y and CONFIG_WIFI=y
4. Build for nrf5340dk/nrf5340/cpuapp

Observe build error.

When i'm building for ncs 3.0, I don't get the error, not sure if the CONFIG_MBEDTLS_LEGACY_CRYPTO_C ensure that PSA and MBEDTLS work together or what causes the difference.

I assume that since nRF7002 is part of plain Zephyr, that you have some interest for it to work with other MCU's.

I have also created a ticket on Zephyr as i don't know who has the responsible of fixing this.

Hi,

We are only supporting the nRF connect sdk, so if you have problems with using zephyr directly you will need to contact them on this one yes.

Hi Kenneth,

Can you at least direct me to something I can look at.

I assume when you placed nRF7002 driver in upstream Zephyr that you at least tested that it worked on your own MCUs?
