Memfault Support for RISC-V on ESP32-C3 Devices​

Memfault now supports RISC-V on ESP32-C3 devices. By following the steps in the ESP32 ESP-IDF integration guide, you will be able to integrate the Memfault Firmware SDK into a system that is using the ESP-IDF, including the ESP32-C3 chip. The integration guide assumes you already have a working project/toolchain for the ESP32. If you do not, the official getting started guide is a great resource.
