Error while unmounting mmcblk1p1 on beaglebone black - during repartitioning and formatting
问题 Hi I'm a newbie of embeded linux. I'm following this tutorial (https://e2e.ti.com/support/embedded/linux/f/354/t/398780?Script-to-Erase-Emmc-independently-Beagle-Bone-Black) for flashing my linux system to beaglebone eMMC. But I have an error: umount: can't umount /dev/mmcblk1p1: Invalid argument This is my cmd : Disk /dev/mmcblk1: 3825 MB, 3825205248 bytes 4 heads, 16 sectors/track, 116736 cylinders Units = cylinders of 64 * 512 = 32768 bytes Device Boot Start End Blocks Id System /dev
