Resize partition user data on the boot SDCard.
I installed Emteria on a 2GB Raspberry PI 4B on a 64GB SDCard. I have to extend the user data partition (which takes up about 8 GB) to occupy at least 24 GB of the SDCard, preferably all the free space. I tried extending it using GParted on a Linux Ubuntu computer. The partition extends but then Raspberry does not boot anymore: the green LED makes 4 quick flashes and then a pause, another 4 flashes and so on. Anyone have any suggestions to fix the problem? Thank you.
