TI中文支持网我在DM385 上编译好了UBOOT 写入SD 卡，使用MKSD_TI81XX.SH 写入SD 卡，却总部成功是怎么回事？我的OS 版本是UBUNTU 16.04 ?
Ternence_Hsu：
你好；
你是用的什么版本的SDK；
是用的PNC_RDK_V3.8.0/Utils/sd-script/mksd-ti81xx.sh 这个文件吗？
写入失败，有什么错误提示吗？

回复 Ternence_Hsu:
如果是制作SD卡失败，你也可以手动了执行；
用 fdisk 来重新分区；
mkfs.vfat -F 32 -n boot "$1"1 &> /dev/nullmkfs.ext3 -L rootfs "$1"2 &> /dev/null
格式化2个分区，分别拷贝数据，具体看看 mksd-ti81xx.sh 的步骤就可以了

我换了ubuntu12.04 出现

这个怎么操作？

你好；
你的SD卡 是dev/sdb 吗？ 你这里命令需要写 /dev/sdb , 不是写/dev/sdb1
这个脚本会重新对sd卡进行分区的，所以下面就报了，找不到sdb11了。

我使用mount 命令查询了设备，显示的是

这个写/dev/sdb1应该是对的！
现在我只想写UBOOT 和MLO ，一步一步的调试！
#!/bin/bash

if ! [[ -e $2 ]]then echo "Incorrect MLO location!" exitfi

echo "All data on "$1" now will be destroyed! Continue? [y/n]"read ansif ! [ $ans == 'y' ]then exitfi
echo "[Partitioning $1…]"

#mount "$1"2 /mnt#tar zxvf $5 -C /mnt &> /dev/null#chmod 755 /mnt#umount "$1"2
echo "[Done]"
我修改了SH 脚本，出现后

实现只写MLO 和UBOOT 怎么操作？

回复 qigong du1:
那你直接把mlo 和 uboot 直接拷贝到sd卡，反正你sd卡格式是fat32 的；
正常，应当启动会有uboot打印的
