Hi Sir
DDR設定問題, 我們使用gel 檔案調整的參數, 想要確定是否真的在CPU 跑起來後, 有設定到位
例如 #define DDR_IOCTRL_VALUE (0x18B)
這行是設定driving, 對應的暫存器位置會是在哪?
#define DDR_IOCTRL_VALUE (0x18B) //Registers tab: DDR_CMDx_IOCTRL
//******************************************************************
//EMIF parameters
//******************************************************************
#define ALLOPP_DDR3_READ_LATENCY 0x08 //Registers tab: DDR_PHY_CTRL_1
#define ALLOPP_DDR3_SDRAM_TIMING1 0x0AAAD4DB //Registers tab: SDRAM_TIM_1
#define ALLOPP_DDR3_SDRAM_TIMING2 0x246B7FDA //Registers tab: SDRAM_TIM_2
#define ALLOPP_DDR3_SDRAM_TIMING3 0x50FFE67F //Registers tab: SDRAM_TIM_3
#define ALLOPP_DDR3_SDRAM_CONFIG 0x61A05332 //Registers tab: SDRAM_CONFIG
#define ALLOPP_DDR3_REF_CTRL 0x00000c30 //Registers tab: SDRAM_REF_CTRL
#define ALLOPP_DDR3_ZQ_CONFIG 0x50074BE1 //Registers tab: ZQ_CONFIG
謝謝
