# 烧录程序
固件下载地址 (opens new window)，注意根据主板选择固件，如果有PSRAM则选择Firmware (Support for Octal-SPIRAM)
执行命令 esptool.py --port PORTNAME --baud 460800 write-flash 0 ESP32_BOARD_NAME-DATE-VERSION.bin
--chip esp32s3 → 芯片型号
--port COM5 → 串口号
--baud 115200 → 烧录速度
write_flash → 烧录命令
-z → 压缩数据，加快传输
0x1000 → 烧录起始地址（二级 Bootloader标起始地址）
