tiny4412 --uboot移植(1)

开发环境：win10 64位 + VMware12 + Ubuntu14.04 32位

工具链：linaro提供的gcc-linaro-6.1.1-2016.08-x86_64_arm-linux-gnueabi

要移植的u-boot版本：u-boot-2016-11

Tiny4412开发板硬件版本为：

底板： Tiny4412SDK 1312B

核心板：Tiny4412 - 1306

https://blog.csdn.net/sinat_20006769/article/details/79046194

1.获取U-BOOT源码

从FTP站点下载： ftp://ftp.denx.de/pub/u-boot
uboot-2016-09.tar.bz2

2.交叉编译工具链

linux 下安装arm-linux-gnueabi交叉编译器

3.解压裁剪

4.初步移植（拷贝模板）

　　在u-boot/board/samsung目录下基于exynos4412的开发板有：origen、odroid、trats、trats2，但是只有origen支持spl配置，根据exynos4412芯片启动的特点，选择origen作为参考比较合适。

　　　cp -r origen/ tiny4412

　　1）修改 ./board/samsung/tiny4412/tiny4412.c

　　　　　直接修改文件名即可；

　　2）修改 ./board/samsung/tiny4412/Kconfig

添加完相关代码目录后，执行如下命令进行编译uboot：

$ make distclean

$ make tiny4412_defconfig

$ make ARCH=arm CROSS_COMPILE=arm-linux-gnueabi-

可以顺利编译出u-boot-spl.bin 和u-boot.bin文件，此时这个u-boot-spl.bin 和u-boot.bin文件还不能直接用在tiny4412 SDK开发板上，需进一步修改代码。

问题：

编译时提示 Your dtc is too old, please upgrade to dtc 1.4 or newer

./scripts/dtc-version.sh: line 17: dtc: command not found
./scripts/dtc-version.sh: line 18: dtc: command not found
* Your dtc is too old, please upgrade to dtc 1.4 or newer

解决：

apt-get install device-tree-compiler
