Is it possible to mount an SD Card with a CM4 with eMMC? #13

Hi there, as far as I am aware you cannot mount an SD Card to a CM with eMMC.

Even though it's not explicitly stated, the documentation on the Super6c github somewhat misleadingly states in the TroubleShooting Section that

"If your CM4 module has eMMC on board, the SSD drive and TF card can be external mass storage."

I fitted an SD Card in the TF Slot of my CM module with eMMC and could not find the device as external mass storage. Am I missing something? Or is this a mistake in the documentation?

Believe the documentation is wrong here as there is no way to do so unless the board re-wires the relevant pins and provides respective overlays to enable this (this is for example with SPI) That sentence should be removed entirely (PR, eh?) unless it can be clarified/resolved by creator.

TL;DR no, it is not possible with this combination

Let me see, your super6c is booting from EMMC onboard, right? Could you please try to execute this command :

lsblk

and send the feedback to me ?
