PSA error on building WiFi monitor SDK example

[Lavanya_Manohar]

When I try to build the SDK example WiFi monitoring it showing error, 

C:/ncs/v2.6.1/nrf/ext/oberon/psa/core/library/check_crypto_config.h:80:2: error: #error "PSA_WANT_ALG_DETERMINISTIC_ECDSA defined, but not all prerequisites"
80 | #error "PSA_WANT_ALG_DETERMINISTIC_ECDSA defined, but not all prerequisites"
| ^~~~~
ninja: build stopped: subcommand failed.

When I commanded below config line, it is compiling fine. 

# WPA supplicant

# CONFIG_WPA_SUPP=y

What would be the issue ? I doubted SKD installation setup, so I unistall and install again but facing same issue. 

Other than this Blinky examples are working fine.

Hi Lavanya_Manohar,

If you go into the file giving the assert, check_crypto_config.h, you will find there is a check going on:

#if defined(PSA_WANT_ALG_DETERMINISTIC_ECDSA) && \
    !((defined(PSA_WANT_KEY_TYPE_ECC_KEY_PAIR_BASIC) || \
       defined(PSA_WANT_KEY_TYPE_ECC_PUBLIC_KEY)) && \
       defined(PSA_WANT_ALG_HMAC))
#error "PSA_WANT_ALG_DETERMINISTIC_ECDSA defined, but not all prerequisites"
#endif

It suggests other configurations that PSA_WANT_ALG_DETERMINISTIC_ECDSA depends on are not enabled. Simply enabling the necessary configurations should fix it.

CONFIG_WPA_SUPP helps likely because it selects those dependencies.

Hi, 
While build with cpuapp_ns configuration facing this issue.
Build without ns is copiling and working fine.

Hi Lavanya_Manohar,

That's because when you build with a non-secure (_ns) target, you build with TF-M, and there will be changes in default cryptography configurations. See: https://github.com/nrfconnect/sdk-nrf/blob/v2.6.1/modules/hostap/Kconfig#L84-L89.

Thus, you need to make some adaptations.

Having said that, I agree that it would be great that dependency of default configurations should be resolved out-of-the-box, so I have reported this internally. Our apologies for the inconvenience.

What changes would I do to resolve this? Please explain

I already answered that in my first reply...

There are some dependencies that are not satisfied. You just need to enable them.
