4412 TF/SD 卡启动问题
按照手册上制作 TF/SD卡启动， 但是调试串口没有任何输出，没有启动起来， 试过 Kingston ， Sandisk TF卡，试过 Samsung SD 卡，都不行， 拨码开关 测试相应电平没有问题，OM5->OM2 = 001
请问版主，你们这开发板 对TF/SD卡 容量大小 和 型号有要求吗， 还有 eMMC 和 TF/SD 卡的uboot镜像 是一样的吗？

你接上屏幕看看能启动么？
确认串口接对了，及时烧写出现错误，串口也是有输出的~ |

1.接的是COM3 从emmc是能启动的，这个系统是你们出厂时烧写好的， 现在按照你们写的用户手册，制作SD烧写卡，往SD/TF卡烧写了uboot 但是上电后串口没有任何信息。 你说的即使烧写出错，串口也有数据，这个数据是从哪里来的呢
2. 拨码开关 还有种组合 也是从EMMC 启动，但是 uboot 启动中途报错了 不知你们发现这个问题没有（OM[5:1] ===> 00100） |

量过，电平是对的，你们用过哪些SD/TF 卡做过实验啊 |

看你的log信息，操作都是正确的，烧写的是光盘的uboot，还是你自己编译的 |
