Axon 32GB eMMC showing only 13GB on Ubuntu image (Partition /dev/mmcblk0p6 full)

[Ena]

I recently purchased a Vicharak Axon with 32GB of eMMC storage and flashed the official Ubuntu image. However, my root filesystem partition is only utilizing ~13GB of the total capacity, and it has already hit 98%-100% disk usage, causing system performance constraints.

Here is the current output from my df -h:

Use code with caution.

Could you please provide the recommended steps or specific tools to safely resize on this board configuration to reclaim the missing storage without corrupting the existing OS installation?

Thanks for your help!
