S5PV210开发 -- 通过 SD 卡烧写
如需转载请注明出处：https://blog.csdn.net/qq_29350001/article/details/78329328
上文 烧写/启动模式 提到使用 SD 卡启动。那么接下来看看怎么做。
一、首先备份
一开始购买的开发板是 Android 系统的，将拨码开关调到 SD 启动模式下。按POWER按钮，备份一份在 SecureCRT 下查看的启动信息。

二、破坏iNand中的bootloader以从SD2启动
注意，如果此时将SD卡拔出，重新启动，开发板还是可以进入系统的。说明此时bootloader是从 iNand 启动的了。默认 CPU 会首先从 iNand 启动，如果 iNand 没有数据，才会从 SD2 启动。
但是你想象一下，刚买的未烧写程序的开发板。该如何烧写呢？为了演示所以我们需要先将 iNand 中的 bootloader 破坏掉。
破坏开发板 android 平台下的 bootloader，从 SD2 启动开发板
进入 android 系统控制台，执行如下指令：
busybox dd if=/dev/zero of=/dev/block/mmcblk0 bs=512 seek=1 count=1 conv=sync
为了确保执行数据有效，再执行 sync 同步一下，即可破坏掉前一个块的数据。
同理，如果是破坏开发板 linux 平台下的 bootloader，从 SD2 启动开发板
进入 linux 系统控制台，执行如下指令：
busybox dd if=/dev/zero of=/dev/mmcblk0 bs=512 seek=1 count=1 conv=sync
为了确保执行数据有效，再执行 sync 同步一下，即可破坏掉前一个块的数据。
三、分析
现在好了，开发板无法启动了... 再次上电出现错误 SD checksum Error
通过SD卡烧写，有两种方式：
第一种，在Windows下 使用 x210_Fusing_Tool.exe 烧写 uboot.bin
第二种，在Linux下 使用指令 sudo ./sd_fusing.sh /dev/sdb 烧写 uboot.bin
甭管那种把，先把 SD 格式化了再说。
四、Windows 下烧写
首先将第一种在Windows下烧写，使用工具 第一种 x210_Fusing_Tool.exe
将 SD 插入PC 格式化完后，打开 x210_Fusing_Tool.exe 软件。
确认一下 SD/MMC Drive 是不是你的SD卡可移动磁盘；Browse 选择你要烧写的 uboot.bin；点击 Add，在PATH下面会出现相应的地址，记得在其前面打对勾；点击 START 等待一会弹出如下窗口，则烧写 uboot.bin 完成。
五、Linux 下烧写
（1）首先是需要重新给 SD 分区
在Ubuntu下，插入SD卡，查看设备节点 cat /proc/partitions
使用 fdisk /dev/sdb 命令删除原来所有分区， sdb 为系统为 SD 卡分配的设备节点。
输入 d，表示删除分区，输入 w 表示保存已经修改的分区信息。至此，原/dev/sdb1 被删除。
拨掉 SD 卡，再插入 PC 机上，查询设备节点 cat /proc/partitions
注意必须拨掉后再插入，否则仍然会提示存在/dev/sdb1 节点，会造成出错。
然后使用 gparted 工具给 SD 卡预留 256M 空间，用于存放 uboot 映像。
Ubuntu上安装 gparted，使用指令 sudo apt-get install gparted 即可
使用方法：
输入 gparted /dev/sdb 进入如下界面。
点击 Partition->New
出现如下界面，在Free space preceding 处填写 256；File system 处选择 fat32；点击 Add
然后再点击对勾，即应用全部操作，然后根据提示点击，到此完成SD卡的分区。
（2）烧写 uboot
一开始如果你没有编译uboot的话，我先提供一个。
注意，这里面的 uboot.bin 有Linux和Android系统之分的。不能用Linux系统的uboot 烧写android的内核的，这一点要搞清楚的。
下载：sd_fusing.sh 脚本
然后执行 ./sd_fusing.sh /dev/sdb
到此 Linux下 烧写 uboot.bin 完成！
六、利用 fastboot 更新
将 SD 卡插入开发板，拨码开关选择 SD/MMC 启动模式，连接 USB OTG 口到 PC 机。
在 SecureCRT 连接成功。可以进入 uboot。
执行 fastboot 指令，弹出界面如下：
然后利用 fastboot 烧写，但是理想很很丰满，显示很骨感。
其中执行 fastboot指令时，出现一个问题：waiting for device
经查询是因为没有 fastboot 所需要的驱动 Android 1.0
更新驱动，驱动文件有提供的，所在位置是：
注意，最好该路径没有中文。我吃过这种亏。
但是又出现问题了，显示错误 文件的哈希值不在指定的目录文件中。
解决方法 ：
1、找到WIN10的设置，点击“设置”
2、点击最后一个“更新和回复”，然后点击“恢复”
3、点击“恢复”之后，在右边点击高级启动下面的“重新启动”，此时电脑会重新启动，如果有其他重要程序在跑，请慎重
4、重启之后会出现几个选项，点击选项“疑难解答”
5、然后点击“高级”，启动设置，重启
6、这会重启之后就跳出一个列表，其中有安全模式等选项，也包括这里我们关心的“禁止强制驱动程序签名”
7、选择“禁用强制驱动程序签名”，对应哪个数字就按那个数字（按 F7），之后电脑会重新启动。
8、重启之后，驱动就可以成功安装。若有提示点击继续安装即可。
运行 CMD 进入 fastboot 文件夹下：
此时就可以利用 fastboot 完成烧写了：
其中fastboot的烧写指令分Linux系统Android系统。
技巧：将uboot、内核、文件系统与fastboot放在同一目录下可以省略它们的目录，如此还方便一点。
《1》烧录linux+QT
fastboot flash bootloader linuxQT/uboot_inand.bin 烧uboot
fastboot flash kernel linuxQT/zImage-qt 烧linuxkernel
fastboot flash system linuxQT/rootfs_qt4.ext3 烧rootfs
uboot的参数不用特意设置（因为我们刷了专为linux+QT定制的uboot，这个uboot中估计已经预制好了所有的启动参数）
《2》烧录android2.3
fastboot flash bootloader android2.3/uboot.bin 烧uboot
fastboot flash kernel android2.3/zImage 烧linuxkernel
fastboot flash system android2.3/x210.img 烧androidrom
注意：android2.3中使用了串口0，所以启动后要把串口插到串口0中，不然串口没有任何启动信息出来。android2.3中屏幕上的logo是在左上角（也是个刷机成功的标志）
《3》烧录android4.0.4
fastboot flash bootloader android4.0/uboot.bin 烧uboot
fastboot flash kernel android4.0/zImage-android 烧linuxkernel
fastboot flash system android4.0/x210.img 烧androidrom
七、启动开发板
将 OTG 线拔出，然后将拨码开关调到上面，即 SD/MCC 启动模式。
OK，启动成功！！到此烧写完成！！
