求助飞思卡尔FAE大神们:
我们买了一块SABRE i.mx6q开发板,但是跟板子来的是andriod系统,我们现在想用SD卡安装Ubuntu的Linux。我们按照http://community.freescale.com/docs/DOC-95015的步骤,在装U-boot时遇到了问题。
随板子来的SD卡格完后,用fdisk查看: fdisk -l /dev/sdb
Disk /dev/sdb: 7948 MB, 7948206080 bytes
255 heads, 63 sectors/track, 966 cylinders, total 15523840 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
Disk identifier: 0x00000000
Device Boot Start End Blocks Id System
/dev/sdb1 2048 15518789 7758371 b W95 FAT32
之后运行
$ dd if=u-boot.imx of=/dev/sdb bs=1k seek=1
$ sync
也没有报错,但是为什么SD卡里没有显示里面有u-boot.imx呢?
而将这个SD卡插入SABRE板子里上电,弹出的信息如下:

FAE大神,我的操作哪里有问题吗?而且我将编译后的内核按照http://community.freescale.com/docs/DOC-95017的步骤考入SD卡,也没有效果。我感觉还是u-boot的原因,是不是板子的内存里还有一个U-boot?。板上的SW6-Boot Mode Selector Switch开关是否需要配置从SD卡里的U-boot启动?
