https://devzone.nordicsemi.com/f/nordic-q-a/118427/psa-persistant-key-usagehello . i tested the sample for the persistance key it worked with the AES key . But when i tried with the EDDSA key i received that error psa_generate_key failed! (Error: -134). ############### main.c ################ #define SAMPLE_PERS_KEY_IDen-USTelligent Community 13Tue, 28 Jan 2025 13:59:09 GMThttps://devzone.nordicsemi.com/thread/520378?ContentTypeID=1Tue, 28 Jan 2025 13:59:09 GMT137ad170-7792-4731-bb38-c0d22fbe4515:e7ee247e-9a03-4d65-ba86-1c06f6e47d41kelk<p>i fixed the Problem in the nrf5340dk_nrf5340_cpuapp.conf : the&nbsp;</p> <div> <div><span>CONFIG_PSA_CRYPTO_DRIVER_OBERON was disable .

I suggest debugging a bit to see more precicely why and where this error come from.</p> <p>I am not able to build this as the main.c content is not complete. Can you upload the complete modified sample you are using? (You can either upload in a zip via Insert -&gt; Image/video/file, or insert the filte content. Note that code can be inserted via Insert -&gt; Code to be more readable). Also, which SDK version are you using?</p><div style="clear:both;"></div>
