emulation - linaro-media-create error while booting qemu/linaro -

i have been trying run linaro on qemu. have been next guide, https://developer.mozilla.org/en-us/docs/mozilla/developer_guide/virtual_arm_linux_environment#create_the_vm_disk_image

the linaro-create-media command executes overall gives errors in between. thats why next command, sudo mount giving error of

"invalid offset '' specified"

the linaro-create-media command giving many such errors while fetching files,

failed fetch http://ports.ubuntu.com natty-updates/universe armel packages 404 not found.

natty no longer maintained, i'm guessing that's why repositories downwards , getting 404 errors. can utilize more recent versions of linaro , hwpack: https://releases.linaro.org/15.06/ubuntu example. also, wasn't able mount command work either, found way:

sudo kpartx -avs vexpress.img

you'll see output similar to:

add map loop0p1 (252:2): 0 155584 linear /dev/loop0 63 add together map loop0p2 (252:3): 0 6135808 linear /dev/loop0 155648

from there can mount 2 partitions this:

sudo mkdir /mnt/loop1;sudo mkdir /mnt/loop2;sudo mount /dev/mapper/loop0p1 /mnt/loop1;sudo mount /dev/mapper/loop0p2 /mnt/loop2

even so, didn't have much luck getting boot properly, maybe you'll have improve luck.

also don't forget umount before trying boot:

sudo umount /mnt/loop1;sudo umount /mnt/loop2;sudo kpartx -dvs vexpress.img
