Hi everyone,

I've always used the a scrip based on mkcard.sh script:

http://downloads.angstrom-distribution. ... mkcard.txt

to build my sdcard because I'm get used to working with buildroot.

https://github.com/oscargomezf/raspberr ... /mkcard.sh

My host platform is Ubunutu 15.10. I've tried to make a new sd card partition and sfdisk has failed, when I tried to execute the script it failed in this part of the code:

Code: Select all

	echo ,9,0x0C,*
	echo ,,,-
} | sfdisk -D -H 255 -S 63 -C $CYLINDERS $DRIVE
The error:

Code: Select all

sfdisk: invalid option -- 'D'

 sfdisk [options] <dev> [[-N] <part>]
 sfdisk [options] <command>

Display or manipulate a disk partition table.

 -u, --unit S              deprecated, only sector unit is supported

 -h, --help     display this help and exit
 -v, --version  output version information and exit

Available columns (for -o):
 gpt: Device Start End Sectors Size Type Type-UUID Attrs Name UUID
 dos: Device Start End Sectors Cylinders Size Type Id Attrs Boot End-C/H/S
 bsd: Slice Start End Sectors Cylinders Size Type Bsize Cpg Fsize
 sgi: Device Start End Sectors Cylinders Size Type Id Attrs
 sun: Device Start End Sectors Cylinders Size Type Id Flags

For more details see sfdisk(8).
It seems to be, the option -D (dos compatibility) it' doesn't exist anymore. My current sfdsik version from util-linux is:

$ fdisk -version
fdisk from util-linux 2.26.2

Any suggestions?

Any one knows If tis there a new mkcard.sh script to manage with the new version of fdsik?

Best regards.

You can remove these lines:

Code: Select all

	echo ,9,0x0C,*
	echo ,,,-
} | sfdisk -D -H 255 -S 63 -C $CYLINDERS $DRIVE > /dev/null 2>&1
And add these lines:

Code: Select all

sudo sfdisk $DRIVE << EOF
Also you can remove all the code related to CYLINDERS value compute.
