For a project we would like to add additional storage on a board, but prefer not to use an sd card slot + sd card.
Is it possible to use an eMMC on a Verdin imx8x plus on the SDIO interface? It is a 4 bit bus compared to the 8 bit used for the on board eMMC and we where wondering if this is an issue?
As you can see in the datasheet of the Verdin iMX8M Plus in Chapter 5.14 the second SDIO interface is “Always compatible” and is provided for your exact intention.
Thanks for the message, I thought it would be compatible but wanted to be sure before we design a board wiht eMMC on this interface. Thanks for clearing it up.
