DM385 sd 卡映像写入不了SD 卡

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？

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/null
mkfs.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

sudo ./mksd-ti81xxuboot.sh /dev/sdb1 MLO u-boot.bin
[sudo] password for hp:

这个怎么操作？

qigong du1 说：

sudo ./mksd-ti81xxuboot.sh /dev/sdb1 MLO u-boot.bin

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   

hp@hp:~/yourapp/Utils/sd-script$ mount
/dev/sda1 on / type ext4 (rw,errors=remount-ro)

hp@hp:~/yourapp/Utils/sd-script$ 

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 [[ -z $1 || -z $2 || -z $3 ]]
then
echo "mksd-ti814x Usage:"
echo " mksd-ti814x <device> <MLO> <u-boot.bin> <uImage> <rootfs tar.gz >"
echo " Example: mksd-ti814x /dev/sdc MLO u-boot.bin uImage nfs.tar.gz"
exit
fi

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

if ! [[ -e $3 ]]
then
echo "Incorrect u-boot.bin location!"
exit
fi

#if ! [[ -e $4 ]]
#then
# echo "Incorrect uImage location!"
# exit
#fi

#if ! [[ -e $5 ]]
#then
# echo "Incorrect rootfs location!"
# exit
#fi

echo "All data on "$1" now will be destroyed! Continue? [y/n]"
read ans
if ! [ $ans == 'y' ]
then
exit
fi

echo "[Partitioning $1...]"

DRIVE=$1
dd if=/dev/zero of=$DRIVE bs=1024 count=1024

SIZE=`fdisk -l $DRIVE | grep Disk | awk '{print $5}'`

echo DISK SIZE - $SIZE bytes

CYLINDERS=`echo $SIZE/255/63/512 | bc`

echo CYLINDERS - $CYLINDERS
{
echo ,9,0x0C,*
echo 10,,,-
} | sfdisk -D -H 255 -S 63 -C $CYLINDERS $DRIVE

echo "[Making filesystems...]"

mkfs.vfat -F 32 -n boot "$1"1 &> /dev/null
mkfs.ext3 -L rootfs "$1"2 &> /dev/null

echo "[Copying files...]"

mount "$1"1 /mnt
cp $2 /mnt/MLO
cp $3 /mnt/u-boot.bin
#cp $4 /mnt/uImage
umount "$1"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 

[Partitioning /dev/sdb1...]

1024+0 records out

实现只写MLO 和UBOOT 怎么操作？

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
