6678EVM调试K1_STK_v1.1例程中GE_test的时候报错：DDR3 leveling has failed, STATUS = 0x40000064的解决办法

在调试K1_STK_v1.1例程中GE_test的时候，使用的是TMDSEVM6678LE板子。

最开始一直报错DDR3 leveling has failed, STATUS = 0x40000064。

一开始以为是DDR配置的问题。

后来发现我添加了gel文件，已经对DDR初始化了。

所以将程序中的KeyStone_DDR_init (66.66667, 20, 1, NULL);注释掉，直接使用gel就成功了。

	//DDR init 66.66667*20/1= 1333
	//KeyStone_DDR_init (66.66667, 20, 1, NULL);//将这一句注释掉

总之，注释掉程序里的DDR3初始化，将CCS自带的gel加进去就可以了。

成功运行的console：
