Sorry about that, that'll teach me to think I can get away with a quick answer
from an iPhone.
Here again:
if $IS_SD_CARD; then
printWarning "adjusting sdcard's partitions"
set +e
command="sudo partprobe /dev/$DEVICE"
echo "$command"; $command
sudo udevadm settle
command="sudo e2fsck -f /dev/${DEVICE}2"
echo "$command"; $command
command="sudo parted /dev/${DEVICE} resizepart 2 '100%'"
echo "$command"; $command
sudo udevadm settle
command="sudo resize2fs /dev/${DEVICE}2"
echo "$command"; $command
set -e
sync
fi
Sow we use a wrapper script called "writewic
/path/to/tmp/image/deploy/myimage.wic /dev/sdX". It is invoked completely
outside bitbake, post image build.
It will raw write (using dd or the like) to the device, then run the bit I
pasted above.
I think this should/could be part of the poky/scripts directory as it is
generic code which anybody could use. (I didn't check if someone already did
something like this in there or in poky-contrib)
Cheers!

Hi Jean-François,
The script looks formatted weird in my email, but how is this script run or
where? Is it part of bitbake, or separately? Do you use the wic output
file, etc...?

Hi Giordon
We use a helper script to perform the raw write, then partition expansion.
Her’s an extract:
if $IS_SD_CARD; then printWarning "adjusting sdcard's partitions" set +e
command="sudo partprobe /dev/$DEVICE" echo "$command"; $command sudo udevadm
settle command="sudo e2fsck -f /dev/${DEVICE}2" echo "$command"; $command
command="sudo parted /dev/${DEVICE} resizepart 2 '100%'" echo "$command";
$command sudo udevadm settle command="sudo resize2fs /dev/${DEVICE}2" echo
"$command"; $command set -e sync fi
Hope it helps. --

[meta-xilinx] Using wic to generate sd-image and writing it correctly
Hi all, Do you know how to get the filesystem partition to auto-expand to the rest of the disk space? I followed some of the instructions here: https://www.yoctoproject.org/docs/2.3/dev-manual/dev-manual.html#creating-wic-images-oe using `dd` to flash the SD card that I have. Looking at it from Disk Utility (on Mac), I see the two partitions (great!) but the Linux partition only takes up 150MB instead of the expected rest of the SD card. Is there a way to resize that partition? Is this just not possible, or should I be writing a custom wks that defines the size of the second partition? Where should I start?
