This is not true. There are many signalling modes for SD and eMMC, few of which work for both of them. As a result there are some controllers that only support one or the other (e.g. in R-Car SoCs). > If a board designer is stupid enough to connect the eMMC > instead of the SD card on the controller looked first by the on chip > ROM, then it's not an argument to not support all the others boards that > did it the right way.
