Wang Xiaoguo,
你使用的卡必须符合下面的标准:
The device includes 3 MMC/SD/SDIO Controllers which are compliant with MMC V4.3, Secure Digital Part
1 Physical Layer Specification V2.00 and Secure Digital Input Output (SDIO) V2.00 specifications.
下面的信息可以在TRM里面找到:
It may be possible to design the system so that an eMMC/eSD memory type is connected to the
MMC1 interface.
简单来说,只要符合标准,接口信号和SD一致,卡本身大小不是问题。
