c6638 DDR初始化动态加载

请问您的代码是搬到DDR3里运行的吗? 如果是的话，需要在搬移之前初始化DDR3。
The RBL also provides an ability for the user to configure the DDR EMIF before loading the image into the external memory during the boot process using a DDR structure. This structure is reserved in the L2. For every section that the RBL reads, it verifies if the DDR enable magic word is set. If the magic word is set, then the DDR structure is used to initialize the DDR. The structure definition of the DDR varies from device to device. See the device-specific data manual for the DDR configuration structure.

我是将GEL文件中的代码改写成C函数，运行在二级缓存，让他初始化DDR3A，目前的问题是连接仿真器烧写进去可以初始化DDR3A，没有连接仿真器通过PCIE加载进去，发现程序也跑完成了，可是DDR3A没有被初始化。

用仿真器跟一下pcie加载后的代码运行情况，看有没有运行到DDR初始化那块代码。

请问一下，具体是怎么实现的呢？
