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
