Hi all
I have a question about pull-up resistor of CMD line.
Here is a comment about pull-up resistor of CMD line in P10 of SABRE-AI_DualLite_CPUcard/sch-27767_a_x3.pdf.
"SD, SDXC - Remove CMD pull-up resistor (default)"
Does it mean user can remove CMD pull-up resistor when use only SD,SDXC ?

Hello,
The pull-up on CMD is intended for eMMC, where it can be open-drain.
Have a great day,
Yuri

Hi Yuri Muhin
In my understanding, open-drain requires pull-up.
Since the internal pull-up of i.MX 6 can be used, it is not necessary to provide a pull-up resistor externally.
Am I correct ?
