Linux 闪存yocto u-boot至ssd卡

我必须在ssd卡dev/mmcblk0上闪存u-boot，该卡的u-boot分区为fat32 mmcblk0p1，linux文件系统分区为ext3 mmcblk0p2。在第一个分区之前有1 mb的空闲空间，其块大小为512 kb，因此我使用dd，如下所示：

$ sudo dd if=u-boot.imx of=/dev/mmcblk0p1 bs=512 seek=2 conv=fsync

我得到了

598+0 records in
598+0 records out
306176 bytes (306 kB) copied, 0,0247659 s, 12,4 MB/s

但是当我通过xfce挂载分区时，我收到一条奇怪的消息：

Sorry, could not display all the contents of “4417-3F91”: Error   whengetting information for file '/media/user/4417-3F91/╒Åâª╞â.┌Åâ': Input/output error

无论如何，分区会被挂载，而ls获得的内容是

问题是什么？

问题是您写入了mmcblk0p1，它是mmcblk0的第一个分区，而不是mmcblk0本身
