Dear NXP,

I am using imx8M Nano evk board with 16GB emmc, after flashing linux images now i am only able to see 8GB emmc size only if run df -h command but i can see complete size if run fdisk -l, so now my question is why i am not able to see complete emmc size with df command or what next need to be done.

root@imx8mnevk:~# df -h

Hello Shilesh,

When you flashed the image from NXP release, eMMC partitions is not fully mounted. So if you use the command " df -h", system only list these partitions were mounted on.

If you want to use full eMMC size, please use "fdisk "commands listed in iMX Linux User Guide to extend your systemfile.

Best Regards,

Peter
