+# 02_esp-gen-no-std
+
+This is an example of using ESP-IDF using no std.
+When flashed to a device, the application just adjusts the intensity of the on-board LED for visual verification that flashing works correctly.
+
+Steps used to generate this project
+
+```bash
+cargo install esp-generate
+esp-generate --chip esp32 esp-gen-no-std
+```
+
+You will also need to install [probe-rs](https://probe.rs/docs/getting-started/installation/)
+
+```bash
+curl --proto '=https' --tlsv1.2 -LsSf https://github.com/probe-rs/probe-rs/releases/latest/download/probe-rs-tools-installer.sh | sh
+```
+
+Steps to build and flash this project
+
+```bash
+# Install espflash if you don't have it already
+cargo install espflash
+
+# Export esp-idf build environment
+. ~/export-esp.sh
+
+# Build and flash to the device
+cargo build
+cargo run
+```
+
+If you encounter this error during the build, you need to export the esp-idf build environment with `. ~/export-esp.sh`
+
+```bash
+error: linker `xtensa-esp32-elf-gcc` not found
+  |
+  = note: No such file or directory (os error 2)
+
+error: could not compile `03_esp-gen-no-std` (bin "esp-gen-test") due to 1 previous error
+```
+
+For more detailed information on setting up a development environment, see [the esp/rust README](/esp/rust/README.md)
