你好,nxp 工程师:



我的板子: imx6dl    

我用的 镜像 是通过下面命令生成的

bitbake fsl-image-mfgtool-initramfs




我现在通过 mfgtool 烧写 出现的问题

在第一阶段(即烧写到 sdram 中 的过程),烧写uboot 启动后出现   就 出现 no  device



按照正常的流程是kernle 起来后才会出现   no device  connetcted    一瞬间

然后又立马识别。 紧接着烧写第2阶段====== 正常的流程是这个样子的。




我现在的板子的otg  id  是悬空的   不知道是不是有影响。




我的是uboot 就出现了   no  device      然后一直都是 no device     导致 kernel  挂载 不了文件系统;


下面是  debug
