The BUCK4 is part of the pca9451, which in turn is not a regulator in barebox, so there is a problem during initialisation: WARNING: imx-esdhc 42860000.mmc@42860000.of: Failed to get 'vmmc' regulator (ignored) Since the dependency could not be resolved, the reg_usdhc2_vmmc regulator is not correctly initialized, leaving the gpio in a floating state, which results in the GPIO being low, which in turn disables the SD-Card.
