系统起来后识别的EMMC大小不对



我在uboot 阶段可以识别emmc大小也对,可以在后面的扇区读写,

可以我netboot 起来后,执行dd if=/dev/zero of=$DRIVE bs=4k count=1,fdisk -l /dev/mmcblk1

结果显示:

Disk /dev/mmcblk1: 4 KiB, 4096 bytes, 8 sectors
Units: sectors of 1 * 512 = 512 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes

只有8个sectors, 为什么会这样?
