the way of expand rootfs

Question

Please tell me the wayt o expand the way of expand rootfs.

I use the woifson audio card for hi-resolution audio sources.

I installed "wolfson_3.10_master.img" into my Raspberry pi B board. I want to expand rootfs to store various hi-resolution audio sources in SD card.

But I could not use expand_rootfs(respi-config) at "wolson_3.10_master.img".

I checked a lot of blogs to do it.

It seemed popular to delete heidden Linux partion and make new partion and use resizefs2x.

I tried it as below ,but I could not expand rootfs,

(1)I chcked the status of partions by fdisk , p.

sudo fdisk /dev/mmcblk0

Command : p

(2)I got the result as below.

(3) I deleted /dev/mmcblk0p6 and made new partions:mmcblk0p4 and mmcblk0p6.

(4) I did "Reboot", but the Kernel was halted during the booting.

(5) I never expanded rootfs.

I'd really appriciate it if anyone tell me the way to expand rootfs.

Ok I see you did not use contiguous partitions.

Reimage the card with original wolfson_3.10_master.img
print the partitions like above.
create a new partition at the end with a mount point "/audio" as big as you can.
reboot Pi
You now have extra storage in "/audio" to use as you wish.

Let me know if this works by marking this "correct" or post errors comments otherwise. Use sd card - How can I resize my / (root) partition? - Raspberry Pi Stack Exchange as a reference only for howto.
