根据报错帮您找了一个解决方法，检查一下是不是文件系统解压缩是出问题了https://blog.csdn.net/weixin_37723417/article/details/104531097

发现问题所在了，我先解压资料中的rootfs-qt.tar.bz2，然后再打包成ubi.img，烧录进去报同样的错误！
sudo ./mkfs.ubifs -F -r rootfs-my -m 4096 -e 253952 -c 3966 -o ubifs.img
sudo ./ubinize -v -o ubi.img -p 262144 -m 4096 -s 4096 -O 4096 ubinize-1G.cfg
用这两条命令，先解压再打包那个支持硬浮点的最小文件系统，就可以正确加载文件系统，请问是哪里没有操作正确呢？

请问更换了开发环境后，使用我们的开发环境，问题解决了吗
