conflicting CPU architectures when integrate cc310 library in samples/hello_world board nrf9160dk_nrf9160

[JeanFi]

Hi,

I am a new comer so perhaps I made a mistake during project configuration.

I am using nrf Connect v3.4.2 on Windows. 

I trie to add CC310 libray in sample hello_world to use AES and SHA256 hadware implementation

Here an abstract of .config generated thanks to "configure nRF Connect SDK project"

#
# Crypto libraries for nRF5x SOCs.
#
CONFIG_NRFXLIB_CRYPTO=y
CONFIG_NRF_OBERON=y
CONFIG_HW_CC310_INTERRUPT=y
CONFIG_NRF_CC310_PLATFORM=y
# end of Crypto libraries for nRF5x SOCs.

#
# Nordic Security
#
CONFIG_NORDIC_SECURITY_BACKEND=y

#
# mbed TLS Configuration File
#
CONFIG_MBEDTLS_CFG_FILE="nrf-config.h"
CONFIG_GENERATE_MBEDTLS_CFG_FILE=y
# CONFIG_MBEDTLS_X509_LIBRARY is not set
# CONFIG_MBEDTLS_TLS_LIBRARY is not set

#
# mbed TLS memory configuration
#
# CONFIG_MBEDTLS_ENABLE_HEAP is not set
# end of mbed TLS memory configuration

#
# Backend Selection
#
CONFIG_CC310_BACKEND=y
CONFIG_OBERON_BACKEND=y
# CONFIG_MBEDTLS_VANILLA_BACKEND is not set
CONFIG_NRF_CRYPTO_BACKEND_COMBINATION_0=y

When I build:

I have some issues related to hw_cc310.c file

First, DT_ARM_CRYPTOCELL_310_ARM_CRYPTOCELL_310_IRQ_0 and DT_ARM_CRYPTOCELL_310_ARM_CRYPTOCELL_310_IRQ_0_PRIORITY are not defined

If I add following lines

#define DT_ARM_CRYPTOCELL_310_ARM_CRYPTOCELL_310_IRQ_0 64
#define DT_ARM_CRYPTOCELL_310_ARM_CRYPTOCELL_310_IRQ_0_PRIORITY 1

then I obtain following errors:

1> c:/users/rouault/ncs/v1.3.0/toolchain/opt/bin/../lib/gcc/arm-none-eabi/9.2.1/../../../../arm-none-eabi/bin/ld.exe: error: modules/nrfxlib/nrf_security/src/mbedcrypto_glue/libmbedcrypto_cc310_renamed.a(empty_file.c.obj): conflicting CPU architectures 17/2

1> collect2.exe: error: ld returned 1 exit status

Can you help me?

According to https://developer.nordicsemi.com/nRF_Connect_SDK/doc/latest/nrfxlib/crypto/doc/nrf_cc310_mbedcrypto.html#nrf-cc310-mbedcrypto-readme  CC310 library is compliant with board nrf9160

Thanks in advance

Thanks for the update.

And very interesting you see the same issue with `west`.
I have successfully built using `cmake` + `ninja` and `west` in both windows command prompt and bash.

I have managed to reproduce the issue in SES, and will look into a fix that can go into next release.

You might want to try to build, using the Windows Command Prompt.
Although bash works for many people, then it is not guaranteed to work in all cases.

The Zephyr getting started is based on Windows command prompt.

Hi,

Related to issue 'ccache: FATAL: Could not find compiler "C:\Users\xxx\ncs\v1.3.0\toolchain\opt\bin\arm-none-eabi-gcc.exe" in PATH" it is because in my computer, I have another ccache.exe which is installed (cygwin) 

When I temporarily rename this other ccache.exe, the issue disappears.

JeanFi Thanks for informing, especially as this could be useful for others to know.
