This script will create a bootable SD card from custom or pre-built binaries.
The script must be run with root permissions and from the bin directory of

$ sudo ./create-sdcard.sh

也曾经尝试过在Windows系统下制作SD卡，也是制作成功，但是烧写失败。
不知道具体原因，请求帮助
之前用的Ubuntu1604的64位系统，后来换成Ubuntu1204的64位系统，最后换成Ubuntu1204的32位系统，都不行
Windows系统下，开始是win10系统，后来换成win7系统，也是不行 您烧写时没读到sd卡，换张别的卡试试吧 zhichao 发表于 2019-11-28 11:30
您烧写时没读到sd卡，换张别的卡试试吧
现在手里4个SD卡换着用，应该是烧进SD卡了，因为bin文件和system文件都复制到SD卡里面了 拨码开关是设成sd卡烧写了吗，有试过我们提供的虚拟机吗 zhichao 发表于 2019-11-28 14:25
拨码开关是设成sd卡烧写了吗，有试过我们提供的虚拟机吗
拨码是2，3on，1，4off。就是用的你们的虚拟机 是我们的底板吗，我们手册上SD 卡烧写设置：1 4 On， 2 3 5 6 7 8 Off (On 代表拨到上方，Off 代表拨到下方) zhichao 发表于 2019-11-28 15:11

底板稍作了改动 问题已经解决，看了原版板子的拨码和现有板子的拨码，发现从SD卡启动后，uboot的环境变量不太一样，启动过程中，没有认到SD卡，就是拨码设置的启动方式有问题，修改CPLD程序，改变启动方式后，能够通过SD卡成功升级烧写系统。
