i.MX8 Mini + Yocto 2.5: Can't resize root partition using gparted

[erikly01]

Hi,

I followed the instructions for resizing the partition posted to the Wiki. Everything works up to the point I open gparted.

The mmcinfo command shows the following

u-boot=> mmcinfo
Device: FSL_SDHC
Manufacturer ID: 70
OEM: 100
Name: TB291
Bus Speed: 52000000
Mode : MMC DDR52 (52MHz)
Rd Block Len: 512
MMC version 5.1
High Capacity: Yes
Capacity: 14.6 GiB
Bus Width: 8-bit DDR
Erase Group Size: 512 KiB
HC WP Group Size: 8 MiB
User Capacity: 14.6 GiB
Boot Capacity: 4 MiB ENH
RPMB Capacity: 4 MiB ENH
u-boot=> ums 0 mmc 1

However, after using the gparted command, it shows no unallocated space for the expansion.
sudo gparted /dev/sdb

What should I do to get the unallocated space to match the actual capacity of the mmc part?
How should i resize the partition?

Thanks in advance for you help!

@erikly01 :

For the picture you post, it looks the command you issue isn't correct.
The correct command should be:

sudo gparted /dev/sdb

Instead of:

sudo gparted /dev/sdb2

Or try to fix the corrupted file system, then read partition table again:

Repair corrupted file system:
# sudo fsck -y /dev/sdb
Re-read partition table:
# sudo hdparm -z /dev/sdb
Execute ‘gparted’:
# sudo gparted /dev/sdb
