Hi Susheel,

Can you elaborate it why it is not possible to use the interrupt variant of cc310 library with freeRTOS.

Whether it is possible to have interrupt variant of cc310 with FreeRTOS in next version of Nordic SDK. If yes when we can expect this.

Hi Mohammad,
There is a limitation on that the interrupt variant does not work correctly with RTOS threads.

So for now, it is not possible to use the interrupt variant of this library with FreeRTOS.

Hi,

Is that possible to use the "interrupt" variant of the cc310 library.

Hi,

Thanks for your response.

I have removed the existing libnrf_cc310_0.9.12.a.

Added the same from the ..\external\nrf_cc310\lib\cortex-m4\hard-float\no-interrupts\libnrf_cc310_0.9.12.a

Now it works. Once again thanks Vidar.

Hi,

I'm not getting the error here. Attached is my modified project which I used with SDK v15.3.0.

Hi Vidar Berg,

I have tried by disabling the NVIC_EnableIRQ(CRYPTOCELL_IRQn); in integration_test_plat_utils.c->SaSiError_t integration_tests_setup().

The output,

==================== TEST START ====================
Failed SaSi_LibInit - ret = 0x6
==================== TEST END ====================

Hi,

Please try to use the "non-interrupt" variant of the cc310 library and remove the call to NVIC_EnableIRQ(CRYPTOCELL_IRQn); in integration_test_plat_utils.c->SaSiError_t integration_tests_setup(). This should prevent the library from entering the __WFE loop.
