# 编译配置命令
**克隆工程**
```bash
git clone https://github.com/78/xiaozhi-esp32.git
```
**进入工程**
```bash
cd xiaozhi-esp32
```
**配置编译目标为 ESP32C6**
```bash
idf.py set-target esp32S3
```
**打开 menuconfig**
```bash
idf.py menuconfig
```
**选择板子**
```bash
Xiaozhi Assistant -> Board Type -> Waveshare ESP32-S3-LCD-0.85
```
**修改 flash 大小：**
```
Serial flasher config -> Flash size -> 8 MB
```
**修改分区表：**
```
Partition Table -> Custom partition CSV file -> partitions/v2/8m.csv
```
**编译**
```ba
idf.py build
```
**下载并打开串口终端**
```bash
idf.py build flash monitor
```
