我用的不是evm板,芯片是c6678。程序用的是K1_STK_1010里面的memorytest。
我发现DDR的初始化应该就跟 KeyStone_main_PLL_init(100, 10, 1); KeyStone_DDR_init (66, 20, 1, NULL)吧,但初始化执行到KeyStone_DDR_full_leveling中的判定条件时发现GPDDR_regs->status=0x40000064,从而导致leveing失败,如下图:
请问这个具体怎么解决呢?前面提到的2个初始化函数需要怎么修改输入参数吗?
Zhongnan,
您需要根据您的硬件板情况重新计算DDR参数,请参考DDR初始化文档Keystone I DDR3 Initialization SPRABL2B
