How to flash and monitor:

espflash flash --monitor target/riscv32imc-unknown-none-elf/debug/test-esp3

Or use cargo run by adding to .cargo/ the file config.toml the following:

[target.riscv32imc-unknown-none-elf]
runner = "espflash flash --monitor"

An example of my fool config.toml is:

[target.riscv32imc-unknown-none-elf]
runner = "espflash flash --monitor"

[env]
ESP_LOG="INFO"

[build]
rustflags = [
  # Required to obtain backtraces (e.g. when using the "esp-backtrace" crate.)
  # NOTE: May negatively impact performance of produced code
  "-C", "force-frame-pointers",
]

target = "riscv32imc-unknown-none-elf"
