I have just extended the primary partition of a SD card from the Banana PI itself using Xaneth instructions and I can confirm it worked(Lubuntu 3.0).|
When running fdisk, I had two partitions - both system. First one is small one, like 50-60MB.
The second one was about 3.6GB.
What I did in fdisk was:
1. Deleted the second partition
2. Created new partition - fdisk correctly suggested all values(partitioned number:2; start block, same as start block of the old partition).
3. Issued the w command to write it.
The board has booted up just fine after a reboot and after doing resize2fs I have ~15GB partition.
