这下面是验证过程，用resize-helper.sh不行。还是要用mkfs.ext4+ext2simg直接对img操作呀？

$ sudo apt-get install realpath

$ wget https://github.com/fboudra/resize-helper/raw/master/resize-helper.sh

$ chmod u+x resize-helper.sh

$ sudo ./resize-helper.sh

root@linaro-alip:~# chmod u+x resize-helper.sh

root@linaro-alip:~# ./resize-helper.sh

Warning: The kernel is still using the old partition table.

The new table will be used at the next reboot.

The operation has completed successfully.

Error: Partition doesn't exist.

resize2fs 1.42.12 (29-Aug-2014)                                          

The filesystem is already 506880 (4k) blocks long.  Nothing to do!

Good. I had noticed that img2simg wasn't working fine for me on db410 neither... Glad that we found one that works at least..

I haven't submitted changes in CI jos for db410 to use mkfs.ext4+ext2simg. Fathi is testing that right now. If it works fine we will update all jobs for all images..
