We see sometimes with different DB410c that the boot from emmc hangs. The logs suggest, that /dev/mmcblk0 and /dev/mmcblk1 are interchanged, i.e. sd card and emmc are confused. As we do not have an sd card inserted, and we need rootwait cmd line option to wait for the device to come online, the boot hangs waiting for rootfs to appear. We use OpenEmbedded, if that matters. Does someone have more insights on why this can happen?? Iff it can happen?!
