问题描述
我正在 TQMLS1028A 中使用 Uboot 启动一个开放式工业 Linux。当我在 linux 中进行一些更改并重新启动时，所有配置和文件都被删除。
我在 Uboot 中使用命令 saveenv 出现这个错误
Saving Environment to MMC... Writing to MMC(0)... Failed

这是printenv

=>
创建 Open Industrial Linux distribution (https://github.com/tq-systems/OpenIL) 的 sdcard.img
我执行以下操作 先执行
make tqmls1028a_mbls1028a_defconfig
这会创建一个 .config 文件。我编辑此文件以使用图像构建 tcpdump 和 iperf3，我这样做了
# BR2_PACKAGE_IPERF3 is not set
# BR2_PACKAGE_TCPDUMP is not set
并添加这两个
BR2_PACKAGE_IPERF3=y
BR2_PACKAGE_TCPDUMP=y
然后我运行命令
make all
然后在 output/image 文件夹中我可以找到 sdcard.img。然后使用这个映像，我使用程序 Rufus (https://rufus.ie/) 制作启动设备。然后开机SD卡我把它放在板子里面
解决方法
最后我做的是在TQ-Group的技术客户支持的建议下更改董事会的操作系统
我使用了专门为这个板子设计的 Yocto Poky 发行版
这是您可以找到如何下载它以及如何构建图像的步骤的链接
