      全志的DRAM找不到相关的寄存器描述,芯片手册A733_User Manual_V0.91.pdf里也没有
      SDK里也找不到DRAM初始化的源代码,我想要做一下自己的测试也不行
      有没有大佬知道怎么办

        我之前也遇到过 T113-S4 内存控制器的问题,最后只能对 Ebyte 提供的 T113-S4 主板启动镜像中的 SPL 进行逆向工程。GitHub 上的 awboot 代码库里已经有一些源代码了:https://github.com/szemzoa/awboot

        我不知道 A733 是否也使用了相同的控制器,但还是值得研究一下 GitHub 上的代码。

        Translated from English:
        I had the same problem with the T113-S4 memory controller, and resorted to reverse engineering the SPL that I found in an startup image from Ebyte for their T113-S4 board. There was already some source code available in the awboot repository on github: https://github.com/szemzoa/awboot

        I have no idea if the A733 uses the same controller, but it is worth the try to look into the github code.

          @kim_jin 能力强的可以自己去逆向SPL里的dram库,DRAM控制器的寄存器定义目前只有RK那边最新一代的芯片有提供,AW这边估计有生之年都看不到🙄
