The ESP32-C3-DevKit-RUST-1 features the ESP32-C3 CPU with a RISC-V core.
This board includes the ESP32-C3-MINI-1 module, a 6DoF IMU, a temperature
and humidity sensor, a Li-Ion battery charger, and a Type-C USB.

======
Overview
--------
Initial port to ESP32C3-Devkit-RUST-1 board:
https://github.com/esp-rs/esp-rust-board
Testing
-------
$ ./tools/configure.sh esp32c3-devkit-rust-1:nsh
$ make
$ make flash ESPTOOL_PORT=/dev/ttyACM0
Alternatively you can compile and flash faster this way:
$ make -j flash ESPTOOL_PORT=/dev/ttyACM0
After flashing NuttX in this board use minicom or other serial console
configured to:
Device: /dev/ttyACM0
Baudrate: 9600 8n1
If everything is fine you should be able to get the serial console:
nsh> uname -a
NuttX 10.4.0 55df6e951e-dirty Aug 22 2022 17:12:29 risc-v esp32c3-devkit-rust-1

* Name: board_reset
*
* Description:
* Reset board. Support for this function is required by board-level
* logic if CONFIG_BOARDCTL_RESET is selected.
*
* Input Parameters:
* status - Status information provided with the reset event. This
* meaning of this status information is board-specific. If not
* used by a board, the value zero may be provided in calls to
* board_reset().
*
* Returned Value:
* If this function returns, then it was not possible to power-off the
* board due to some constraints. The return value in this case is a
* board-specific reason for the failure to shutdown.
*
