Hi Mingyao, we dont have any Rex baseboard with eMMC yet. Just have a look at the Sabre SD Reference schematic and instead of using SD4_DATA/CMD/CLK use SD2_DATA/CMD/CLK (page 5 of MCIMX6Q-SMART DEVICE PLATFORM, Page title: eMMC, SPI NOR FLASH). You may need then update your software to support eMMC on SD2.

Mingyao, SST is not on baseboard. Are you planning to use iMX6 Rex module layout?

Hi Mingyao, if you want to use eMMC, connect it to SD interface and dont use the Second uSD slot. Hope it helps, Robert

Hi Mingyao, I apologize for late replay, I was travelling. Use SD2 for eMMC. We designed it the way that it can be connected to the eMMC. Robert
