I'm not an expert on this, does SDR104 need 1.8V?
To my understanding, sd-uhs-sdr50 is the max speed for 3.3V?
Nope, everything with SDR* needs 1.8V. So, classic "highspeed" is the
maximum for your slot.
I ask because on my custom board the hardware guys gave us 3.3V, only, for
the SD slot :(
Pity, in deed.
Yes, indeed :(
Btw, whats about HS400 support for the eMMC? As the eMMC is often the
'mass storage' device for the rootfs, the eMMC performance will have a
direct influence to the overall system performance.
