# 方法一、仅使用于烧写过版本板子，新板子不适用

uboot下tftp烧写 (以太网接eth2) ,需要PC有tftp服务器

启机进uboot 看到Autoboot in 3 seconds字样狂按ctrl +c

```sh
Boot over spi-nand0!
STM32MP> <INTERRUPT>
STM32MP> <INTERRUPT>
STM32MP> <INTERRUPT>
STM32MP>
STM32MP>
STM32MP>
STM32MP>
STM32MP> setenv ipaddr 192.168.137.109
STM32MP>ping 192.168.137.53
```

如果提示没有网口，需要设置下

```sh
setenv ethaddr 10:e7:7a:e1:a2:96
```

ping通提示alive就开始烧写

```sh
STM32MP> tftpboot 0xd0000000 192.168.137.53:rootfs.ubi
Using eth1@5800a000 device

# 方法二、适用于任何板子

1. 需要接飞线接USB，~~让硬件帮忙飞下~~，改版后直接接烧写小板。![image.png|375](https://raw.githubusercontent.com/wangzipai/my_ob_pic/main/20241125161324.png)

2. 去stm32官网下载安装STM32CubeProgrammer
   <https://www.st.com/en/development-tools/stm32cubeprog.html#get-software>

3. usb接入电脑，新板子要接串口，3个boot脚短接
   ![|300](https://raw.githubusercontent.com/wangzipai/my_ob_pic/main/20241125161548.png)

打开软件 ，port 选择加入的USB, connect

选择对应版本下的tsv文件

**旧版子烧写完重启就行了**

**仅新板子烧写需要，不是新板子不要进行下面的操作，**

```sh
# 升级完成后打开串口按ctrl +c
STM32MP> <INTERRUPT>
STM32MP> fuse prog -y 0 9 20400000
Programming bank 0 word 0x00000009 to 0x20400000...
STM32MP> reset
resetting ...
```
