I can boot my hikey 2gb board from both emmc and sd card into debian using recent images. However, when I expand the rootfs to fill the disk, the board will no longer boot from the sd card. This has been the case both when I expand the partition using gparted on a linux box outside the system; or when I use the resize-helper.sh script suggested n the getting started guide. I have tried with a 4GB microsd, a 32GB microshdc and a 64 GB microsxdc all to the same effect.
Unfortunately I do not currently have an operative UART to give me the debugging information at boot to see what is going on when the rootfs partition has been altered.
Does anyone else have any experience of this, or have suggestions about what I must be doing wrong?
