我这边的CPU和SD的参数分别是MMC3.3,SD2.0,可以达到64GB吗?如果不能,最多可以达到多少GB
AM1808的TRM里面有写:
26.1.5 Industry Standard(s) Compliance Statement
The MMC/SD card controller supports the following industry standards (with the exception noted below):
• MMC (Multimedia Card) Specification v4.0
• SD (Secure Digital) Physical Layer Specification v1.1
• SDIO (Secure Digital Input Output) Specification v2.0
The information in this chapter assumes that you are familiar with these standards.
The MMC/SD controller does not support the SPI mode of operation.
用的SD卡要符合上面的协议。
