您好,我使用ddr test工具(V2.60)的步骤如下:

我的DDR芯片资料如下:

MT41K256M16 – 32 Meg x 16 x 8 banks

1, 在xls文件中填好我们板子DDR信息,得到.inc中黄色标记的配置

172766156.jpg

2. 将1步骤得到的配置文件.inc(缺少红色标记的配置)载入ddr test工具,运行后只能得到如下寄存器的数值

# write leveling
MXC_DCD_ITEM(40, MMDC_P0_BASE_ADDR + 0x80c, 0x001E0015) //Bety1-0
MXC_DCD_ITEM(41, MMDC_P0_BASE_ADDR + 0x810, 0x00290025) //Bety3-2
MXC_DCD_ITEM(42, MMDC_P1_BASE_ADDR + 0x80c, 0x00150026) //Bety5-4
MXC_DCD_ITEM(43, MMDC_P1_BASE_ADDR + 0x810, 0x000A001D) //Bety7-6

3.得到2中的配置后,ddr test工具停在writing DQS data的地方不动,整个ddr test工具UI上的按钮均无法点击(灰色)

我的问题是:

1, 上述步骤1,我是否有漏掉什么操作?上述我的步骤1操作是否正确

2. 为什么只能得到步骤2中提到的数据后,ddr test工具貌似死掉了,无法得到后续的结果?

3. 我应该如何正确操作得到想要的结果?或者我应该使用哪一个版本的ddr test工具
