+**配置编译目标为 ESP32：**
+
+```bash
+idf.py set-target esp32s3
+```
+
+**打开 menuconfig：**
+
+```bash
+idf.py menuconfig
+```
+
+**选择板子：**
+
+```
+Xiaozhi Assistant -> Board Type -> AtomMatrix + Echo Base
+```
+
+**修改 flash 大小：**
+
+```
+Serial flasher config -> Flash size -> 4 MB
+```
+
+**修改分区表：**
+
+```
+Partition Table -> Custom partition CSV file -> partitions_4M.csv
+```
+
+**编译：**
+
+```bash
+idf.py build
+```
