Hi,

Would you please check without using PSRAM 4MB to bifercate issue like it is due to PSRAM or something else? So that it will be helpful to debug further as per analysis or traces into deep level.

Thanks. Totally cut out PSRAM from my system is somehow difficult as the data complexity in the system asks for more RAM. Still, the buffer passed to AES API is a static global buffer. It's likely to be on the chip's internal 520K RAM.

I list below another crash log caught a moment ago. To see if it helps.
