Hi NXP team,
I’m working with the S32K389 and testing the AES_ACCEL (ACE/MSC) module. I’ve encountered a stability issue when processing large data buffers.
Test Setup:
- Mode: AES-CBC
- Case 1 (Pass): Encrypting 4KB data works correctly.
- Case 2 (Fail): Encrypting 64KB data causes the chip to crash/hang immediately when the AES service is executed.
Observed Behavior:
- S32DS (S32 Design Studio) freezes during the execution of the AES service.
- Attempts to Attach to the S32K389 via the debugger fail completely.
Questions:
- Are there any known limitations regarding the maximum data length per AES_ACCEL transaction?
