I appreciate it.</p> <p>Yes, it is known that mbedTLS RSA needs a large heap. I try the PR.</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/322246?ContentTypeID=1Wed, 28 Jul 2021 13:06:23 GMT137ad170-7792-4731-bb38-c0d22fbe4515:3dadd2ec-57df-4910-bb57-ac4dbdbc1d46Amanda Hsieh<p>Hi,&nbsp;</p> <p><span>Due to the summer vacation period, we are currently understaffed, so delayed replies must be expected.&nbsp;</span></p> <p>The RSA is not supported in the v1.6.0 release and is listed in the known issues. There is a PR already which solves the issues for both the secure only and the non-secure targets but it is unfortunately not merged yet.</p> <p><a title="https://github.com/nrfconnect/sdk-nrf/pull/5034" href="https://github.com/nrfconnect/sdk-nrf/pull/5034" rel="noopener noreferrer" target="_blank">https://github.com/nrfconnect/sdk-nrf/pull/5034</a></p> <p>In a nutshell, if you are using a secure-only target you can just copy the configuration from my PR and it should work as expected. If you are using a non-secure only target then they need the whole PR.</p> <p>-Amanda H</p><div style="clear:both;"></div>
