esp-println

Provides print! and println! implementations various Espressif devices.

• Supports ESP32, ESP32-C2, ESP32-C3, ESP32-S2, ESP32-S3, and ESP8266
• Dependency free (not even depending on esp-hal, one optional dependency is log, another is critical-section)
• Supports JTAG-Serial output where available
• Supports RTT (lacking working RTT hosts besides probe-rs for ESP32-C3)

RTT on ESP32-C3

The cli utility should work for flashing and showing RTT logs on ESP32-C3 by using it's run command. You need to use the direct-boot feature of the HAL to flash via probe-rs.
