Spagman thanks for the pictures do I have to put a 0.5v 1uF capacitor on the ground ??

Actually.. Nicolayer posted the pictures, we need to give credit to him.

I do not use a capacitor and it works just fine.

Ok thanks @ Nicolayer thank you so much :-) Do I have to put a 0.5 V 1uF capacitor On the ground connection ?

[nicolayer]

Capacitor range from 0,47uF to 2,0uF with working voltage 6v for example.
Why it need ?- one is stable base for Vddi voltage, more info you can find out in JEDEC/eMMC specs.
Capacitor is critical ext element for connected eMMC named Hynix, SanDisk.
And, if you spend some time - can find Vddi capacitor in any board with eMMC memory.
