# /flash — Build & Flash ESP32
Build the firmware and upload it to the connected ESP32.
## Steps
1. Verify `credentials.h` exists:
```bash
test -f rudder-sensor/include/credentials.h || { echo "ERROR: credentials.h missing — copy credentials.example.h"; exit 1; }
```
2. Detect the serial port:
```bash
ls /dev/cu.usbserial-* 2>/dev/null
```
If no port found, tell the user to check their USB cable (charge-only cables
won't work) and that the ESP32 must be plugged in via USB.
3. Build and upload:
```bash
cd rudder-sensor && pio run -t upload --upload-port <detected-port>
```
4. If the build fails:
- Missing `credentials.h` → tell user to copy from example
- PlatformIO SSL/mirror errors → see CLAUDE.md for esptoolpy workaround
- C++ errors → read the failing file and fix
5. After successful flash, offer to open the serial monitor:
```bash
pio device monitor --port <detected-port>
```
## Arguments
- `/flash` — auto-detect port, build and upload
- `/flash monitor` — flash then open serial monitor
