persistent EdDSA key generate ,detroy and generate

[kelk]

Hi! I’m trying to generate an EdDSA key pair and store it in persistent storage. I then delete the keys and regenerate them. However, after a few successful iterations, my program freezes.

I also noticed that when I enable the hardware accelerator (CONFIG_PSA_CRYPTO_DRIVER_CC3XX=y), the program freezes immediately during key generation.

Additionally, I’m having trouble debugging my program, likely due to the large number of files in my project.

I’m using the CPN003 board with SDK v2.7.0. What could be c
