+# 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> 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

+![image.png|400](https://raw.githubusercontent.com/wangzipai/my_ob_pic/main/20241125161646.png)
+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 ...
