SD卡烧写问题
使用SD卡烧写 用户资料/Linux/tools/SD/烧写/256Mnand/createSdCard-qt4 在制作SD卡时成功完成，但却无法烧写，过程如下sudo ./createSDcard.sh
imx6ul 的密码：

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
the SDK
Example:
$ sudo ./create-sdcard.sh
Formatting can be skipped if the SD card is already formatted and
partitioned properly.

卡制作完成以后里面是否有bin和system目录啊，bin,system里面的内容是不是都正确了？
正常都不会有问题，还有你核心板是多大的就烧多大的不要弄混了，SD卡的格式是不是FAT 卡制作完后无法识别，在Windows上提示未格式化 huangyubin 发表于 2018-6-19 11:11

你好，这种情况应该是您在SD卡制作过程中出现了问题，建议您将SD卡重新格式化后，根据用户手册重新制作SD卡进行烧写 现在是这样的情况
