I am designing a board using the 1064 EVK as a reference. I am replacing the Hyperflash by a eMMC on uSDHC 2.
I wish to be able to boot from the eMMC.
My question is how do I switch from 3.3V to 1.8V, is there a dedicated GPIO? or could I use GPIO_SD_B1_07 to switch supply to the eMMC.
I see a boot option to boot from 1.8V on uSDHC 1 but I don't see a similar option for uSDHC 2 in both the HW design guidelines and the schematic.
