Mmc error on just flashed board

I have an Apalis IMX6 IT v1.1B board with ixora carrier board.

I just installed “Apalis-iMX6_LXDE-Image 2.7.2 20170410” using Toradex easy installer and on boot and after bootup I receive the following error continuously. Could this be a hardware fault ?

Angstrom v2016.12 - Kernel 4.1.39-2.7.2+gba2f75f

Apalis-iMX6_LXDE-Image 2.7.2 20170410

What you are seeing is probably an issue with the SD card as mmc0 is what the eMMC of our module is usually running at:

And this are the parameters as reported by the Linux kernel:

Could you try once without the SD card, re-seating the SD card or using a different brand/model SD card and see what happens?
