i.MX93 M33 Firmware ELE (EdgeLock Enclave) API Support - Missing S3MU Driver

Dennis0513 — Thu, 10 Jul 2025 08:06:44 GMT

I'm developing a project that requires independent use of ELE (EdgeLock Enclave) security features in M33 firmware. After SDK analysis, I found:

Missing Files:
drivers/fsl_s3mu.c/.h - S3MU driver implementation
drivers/fsl_ele_base_api.c - ELE base API
boards/evkmimx9352/driver_examples/s3mu/ - S3MU examples

Does i.MX93 architecture support direct M33-to-ELE communication via S3MU?
Are there alternative approaches or technical documentation available?
