Andrei. We can see all dump of ext_csd by using debugfs like this. mount -t debugfs /dev/mmcblk0 /mnt/ cat /mnt/mmc0/mmc0\:0001/ext_csd If user take care of it by showing all dump of ext_csd, we may be comfortable more without having to worry. But most of them that they do not know a lot of information. If we provide some information they need them user friendly, I think that user can use more easily mmc.
