I'm trying to boot a devices (Overo EarthStrom COM), with Yocto Rocko installed on the MicroSD card.
I'm using the latest commit of u-boot (c761a7e) from github.com/.../u-boot.
seems u-boot doesn't recognise the MicroSD card, it gives me the following error. What might be the cause of this problem? Any help will be appreciated.
