imx6ul使用官方SDK裸机及驱动包

实验目的:

编译NXP官网sdk并在实验板上运行demo。

NPX提供了imx6ulSDK包:

i.MX 6ULL应用处理器_Arm® Cortex®-A7单核，频率为900 MHz_NXP 半导体

下载后解压，可在如下目录找到最简单的hello_world demo程序。

/root/SDK_2.2_MCIM6ULL/boards/evkmcimx6ull/demo_apps/hello_world

官方demo依赖于cmake编译。需要按照好cmake环境。

本实验的硬件板卡，用于调试输出都是UART4，默认官方demo是UART1，因此需要修改代码，改为串口4，也比较简单，主要是修改io和串口寄存器。顺着hello_world.c开始修改即可。

修改后重新编译，输出如下:

root@xxzh:~/SDK_2.2_MCIM6ULL/boards/evkmcimx6ull/demo_apps/hello_world/armgcc/ddr_debug# ls
hello_world.elf  sdk20-app.bin

通过uboot加载裸机运行：
