eMMC and LS1046a hardware design

[Ellu24]

Hello

I am doing a new hardware design using ls1046a and now trying to interface eMMC. I have some doubts regarding this.

1) I am planning to use emmc version 5.1 and whether it is supported by  processor or not.

2) to which pin of the processor hardware reset and RCLK of the emmc should connect.

1. Please take a look at sections 19.1.1 and 19.1.2 of the LS1046A Ref Manual, these list  features and protocols supported by the processor. It can work with eMMC 5.1 devices, but supports only eMMC 4.5 features.

2. Please refer to https://www.nxp.com.cn/docs/en/application-note/AN5252.pdf
