Hi all, on kernel 3.16.3 running on an i.MX6 with an eMMC card formatting a partition won't work, it hangs. With an added -v the last thing it spit out is "Discarding device blocks: 4096/196608". When I run mkfs with "-E nodiscard", formatting & booting works. Noteworthy: when the eMMC device was still in virgin mode, partitioning without "-E nodiscard" worked. But last week I used the mmc tool to turn the user space into enhanced format. Basically, I first run "mmc extcsd read /dev/mmcblk0" and used the number after MAX_ENH_SIZE_MULT for an "mmc enh_area set -y 0 7651323 /dev/mmcblk0". Then, after a power-cycle, I also turned bkops on because kernel was complaining that it wasn't enabled. And since the default discard option of mkfs.ext3 doesn't seem to work anymore. -- To unsubscribe from this list: send the line "unsubscribe linux-mmc" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
