Storage partitions

patcharasirigul — Mon, 22 Dec 2014 14:16:17 GMT

Hello everyone,

I have a question about creating storage partitions without MFGTool. I have used mksdcard-android.sh to create partitions but It does't works. It shows :

patchara@ubuntu:~/myandroid$ sudo ./mksdcard-android.sh /dev/sdb

1+0 records in

1+0 records out

1024 bytes (1.0 kB) copied, 0.0188542 s, 54.3 kB/s

Checking that no-one is using this disk right now ...

BLKRRPART: Device or resource busy

This disk is currently in use - repartitioning is probably a bad idea.

Umount all file systems, and swapoff all swap partitions on this disk.

Use the --no-reread flag to suppress this check.

When I used the gparted for checking partitions, It's not show partitions like a table partitions of Android_User's_Guide.pdf in page 13.

Could you help me check my solution ?

Why is not it work ?

Thank you so much.

Hi,

I am using Android Marshmallow and when I am trying to create partitions on SD card; I am getting this warning:

Warning: partition 4 extends past end of disk

When I am trying to boot board from this card, I am getting this message :

mmcblk2: p4 size 12254486 extends beyond EOD, truncated
random: nonblocking pool is initialized

My kernel is getting stuck at this point.
