# 预编译固件(可随时刷写)
当前归档目录:[`cyd_28r/`](cyd_28r/)
对应板子:**CYD ESP32-2432S028R**(ILI9341),LD2420 OT1→GPIO22、RX→GPIO27。
版本信息见 [`cyd_28r/VERSION.txt`](cyd_28r/VERSION.txt)。
## 直接刷写(无需重新编译)
1. USB 连接板子
2. 在本目录执行:
```powershell
cd firmware\cyd_28r
.\flash.ps1
# 或指定端口
.\flash.ps1 -Port COM3
```
也可双击 / 运行 `flash.bat`。
依赖其一即可:
- 已安装 PlatformIO(`pio`,自带 esptool)
- 或 `pip install esptool`
## 手动 esptool
```bash
esptool.py --chip esp32 --port COM3 --baud 921600 write_flash -z ^
--flash_mode dio --flash_freq 40m --flash_size 4MB ^
0x1000 bootloader.bin ^
0x8000 partitions.bin ^
0xe000 boot_app0.bin ^
0x10000 firmware.bin
```
## 从源码重新打包进本目录
在仓库根目录:
```powershell
.\firmware\export_from_build.ps1
# 仅复制、不编译:
.\firmware\export_from_build.ps1 -SkipBuild
```
