AM62A7: 关于MCU R5访问mmcsd的技术咨询

Part Number: AM62A7

问题:MCU-R5是否可以通过自带的emmc驱动去操作mmcsd

细节:在贵司提供的技术文档上,我们查看到如下描述:

Please note that this driver is supported only on DM R5(WKUP R5) as part SBL examples. It is not supported on MCU-R5.

(来源:AM62Ax MCU+ SDK: MMCSD (ti.com)

上述是否意味着现有的驱动无法实现mcu-r5对emmcsd的操作。

诉求:mcu-r5若无法通过现有驱动操作emmcsd,我们需要做哪些修改来实现mcu-r5对emmcsd的操作.
