https://devzone.nordicsemi.com/f/nordic-q-a/51388/cc310-support-under-freertosHi, I&#39;m in the early stages of developing a BLE peripheral device that requires the use of the CC310 CryptoCell on an nrf52840-DK board. I have managed to implement a basic BLE service by modifying the blinky example with elements from the nrf_crypto_ecdh_pca10056en-USTelligent Community 13Mon, 26 Aug 2019 23:36:03 GMThttps://devzone.nordicsemi.com/thread/206202?ContentTypeID=1Mon, 26 Aug 2019 23:36:03 GMT137ad170-7792-4731-bb38-c0d22fbe4515:07e0199c-3e2b-4f48-a284-1024c2ac1da6dj1234<p>Thanks for the response Susheel.</p> <p>I worked out the issue in my particular case.</p> <p>For the benefit of others, it was an issue around memory allocation. As described&nbsp;<a href="https://infocenter.nordicsemi.com/topic/com.nordic.infocenter.sdk5.v15.0.0/lib_crypto_mem_management.html">the SDK docs</a>, the crypto functions require a memory allocator and in my case it was the default. With gcc, this was allocating data on the stack causing a stack overflow. Using a combo of the FreeRTOS allocator and statically allocated data solved my particular issue.</p> <p>dj</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/206028?ContentTypeID=1Mon, 26 Aug 2019 07:55:56 GMT137ad170-7792-4731-bb38-c0d22fbe4515:085656c1-21a0-4a34-ba02-1a7be48f9201Susheel Nuguru<p>Hi,</p> [quote user=""]Does the SDK provide support for the CC310 Crypto Cell under FreeRTOS[/quote] <p>No, We&nbsp;do not officially support the&nbsp; combination of using CC310 with FreeRTOS just because we do not have this combo in our production testing suite, But It should work in the non-interrupt mode as mentioned in the link you provided.</p> <p>/Susheel</p><div style="clear:both;"></div>
