we need an (additonal) eMMC on our Verdin carrier board. As eMMC is like uSD we take that approach with some changes:
We have fixed 1.8V I/O voltage whereas uSD switches between 3.3V and 1.8V.
We do not want to switch eMMC power, instead we have a Reset pin. Verdin pin planner has an optional SD_1_RESET# pin (which seems to be a standard digital I/O).
My question is: Is there a eMMC driver available which halts the voltage at 1.8V and uses the Reset function instead of power cycling?
With such a driver we get a very smart HW solution.
