## 🛠 Build Instructions
|
|
|
|
### Prerequisites
|
|
- PlatformIO CLI or IDE
|
|
- ESP-IDF framework (v5.1+)
|
|
- ESP32-P4-NANO development board
|
|
|
|
### Important: Path Requirements
|
|
**ESP-IDF requires project paths without spaces.** Move the project to a path like:
|
|
- `F:\dev\esp32-p4-audit`
|
|
- `C:\projects\esp32-p4-nano`
|
|
|
|
### Build Steps
|
|
|
|
1. **Move Project** (if in path with spaces):
|
|
```bash
|
|
# Move from current location to path without spaces
|
|
xcopy "F:\dev_shit\p4 bridge" "F:\dev\esp32-p4-audit" /E /I
|
|
cd F:\dev\esp32-p4-audit
|
|
```
|
|
|
|
2. **Build Firmware**:
|
|
```bash
|
|
pio run
|
|
```
|
|
|
|
3. **Upload Firmware**:
|
|
```bash
|
|
pio run --target upload
|
|
```
|
