NRF5340 RSA Example

[persimmon]

The /v1.6.0/nrf/samples/crypto/rsa project on NRF5340 returns the following error right out of the box. psa_generate_key failed! (Error: -134)

I have installed the SDK and the SEGGER debugger using nrfConnect on MacOS as it has been instructed in the info-center and then loaded and executed the RSA example in SEGGER.

Am I missing something?

Hi, 

Due to the summer vacation period, we are currently understaffed, so delayed replies must be expected. 

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.

https://github.com/nrfconnect/sdk-nrf/pull/5034

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.

Thank you for your prompt response. I appreciate it.

Yes, it is known that mbedTLS RSA needs a large heap. I try the PR.
