In WolfSSL release v5.6.4 we have added support for Silicon Labs’ Simplicity Studio. In addition we have tested with the ERF32xG21 series of chips and have created an example setup. More information can be found in the WolfSSL repo.
Using our benchmarking tool, we have the following results from a Cortex M33 at 80MHz:
