快速构建

推荐使用 release 脚本生成完整固件包：

bash
python scripts/release.py m5stack-stopwatch --name m5stack-stopwatch

生成的固件压缩包位于：

text
releases/v2.2.6_m5stack-stopwatch.zip

手动配置

配置编译目标：

bash
idf.py set-target esp32s3

打开配置菜单：

bash
idf.py menuconfig

选择板卡：

text
Xiaozhi Assistant -> Board Type -> M5Stack StopWatch

配置 Flash 大小：

text
Serial flasher config -> Flash size -> 16 MB

配置分区表：

text
Partition Table -> Custom partition CSV file -> partitions/v2/16m.csv

配置 PSRAM：

text
Component config -> ESP PSRAM -> Support for external, SPI-connected RAM -> Select
Component config -> ESP PSRAM -> SPI RAM config -> Mode (QUAD/OCT) -> Octal Mode PSRAM
Component config -> ESP PSRAM -> SPI RAM config -> Set RAM clock speed -> 80MHz clock speed

配置唤醒词实现方式：

text
Xiaozhi Assistant -> Wake Word Implementation Type -> Wakenet model with AFE

编译：

bash
idf.py build

合并固件

手动构建后，可使用以下命令合并烧录固件：

bash
esptool.py --chip esp32s3 merge_bin \
    --flash_mode dio \
    --flash_freq 80m \
    --flash_size 16MB \
    0x0 build/bootloader/bootloader.bin \
    0x8000 build/partition_table/partition-table.bin \
    0xd000 build/ota_data_initial.bin \
    0x20000 build/xiaozhi.bin \
    0x800000 build/generated_assets.bin \
    -o M5Stack-StopWatch-XiaoZhi-v2.2.6_0x00.bin

烧录合并后的固件：

bash
esptool.py -b 1500000 write_flash -z 0 M5Stack-StopWatch-XiaoZhi-v2.2.6_0x00.bin
