Topic: Wolfssl_test build error

Hi

I am trying to implement wollfssl on nrf5340dk by using the wolfssl zephyr port.
I have taken "wolfssl_test" example in which I am getting compilation errors

nrf5340_toolchain_2_1_0\v2.2.0\modules\crypto\wolfssl\wolfcrypt\src\sp_arm32.c:237:26: error: expected '=', ',', ';', 'asm' or '__attribute__' before 'asm'

nrf5340_toolchain_2_1_0\v2.2.0\modules\crypto\wolfssl\wolfcrypt\src\sp_arm32.c:2676:21: error: 'r' undeclared (first use in this function)
2676 |         : [r] "+r" (r), [a] "+r" (a), [b ] "+r" (b)

I get many errors further in the file with the similar 'asm' undefined.

While reading on the internet somewhere I read that only the g++ compiler supports the asm attribute.
So for a trial I added this definition at the beginning of sp_arm32.c

#define asm __asm__   

which resolved the complation issues and the project was built successfully.

Just wanted clarify if the above code is a valid approach or am I missing a necessary configuration in the project?

Re: Wolfssl_test build error

Hi ajmal,

Yes, that is certainly a valid approach.  But of course, you should not need any workarounds ideally.
Can you please confirm which wolfSSL version you're on, and what toolchain you're using?  This will assist us in fixing this upstream.

Thanks,
Kareem

Hi,

    I am trying to run the example code "wolfssl_ts_sock" on the zephyr port on the nrf5340 device.
    But the application fails to load the CA certificate and following error is printed on the console
    ERROR: failed to load CA certificate
    Client return -1
    Client memory stats
    static memory was not used with sslDone
    Server return -1

Re: Wolfssl_test build error

Hi,

Please enable wolfSSL debug logging by defining CONFIG_WOLFSSL_DEBUG/DEBUG_WOLFSSL and attach a debug log here.
Please also attach the cert you are trying to register.
If this is sensitive information, please contact us at support [AT] wolfssl [dot] com.

Re: Wolfssl_test build error

Our date check is failing: Date BEFORE check failed
This normally happens when your system time (RTC) is not set correctly, are you confident this is set correctly on your system?
Note that, on Zephyr we use clock_gettime with a clock ID of CLOCK_REALTIME.  I would confirm this is returning the correct time for you.  See z_time in wolfcrypt/src/wc_port.c.
