        我的初步想法是用·SPI去访问？看了全志的SPI的文档，现在还不知道咋设计。

            @tigger D1开发板，我移植了rustsbi到D1开发板上，想加一个读写SD卡的功能。

              @wt2521 这样其他软件就可以调用sbi的sd卡读写？

                  @cube_work rustsbi读写外置sd卡，以后可以更便捷载入文件系统或者os等

                    @wt2521 感觉问题不大，可是为什么不用SDIO，而要用SPI呢？

                        @cube_work 因为之前有人在K210开发板上移植rustsbi时，开发的sd卡存储驱动用了SPI
