CoreMP135 Partition Resize
1. Resize Script
In versions M5_CoreMP135_debian12_20240507/M5_CoreMP135_buildroot_20240508 or later, an expansion script named resize_mmc.sh is provided under the /usr/local/m5stack path. You can execute it directly for automatic expansion, and a reboot is required after completion.
cd /usr/local/m5stack
./resize_mmc.sh2. core-config
Use the core-config tool to perform expansion.
core-config
3. fdisk
Follow the steps below to perform expansion using the fdisk command.

Recreate Partition
1.Use the d command to delete partition #10
Command (m for help): d
Partition number (1-10, default 10): 10
Partition 10 has been deleted.2.Create a new partition. Note: The First sector address of the new partition must match the original partition (183330), otherwise data loss may occur. When prompted to remove the existing partition signature, select no.
Command (m for help): n
Partition number (10-128, default 10):
First sector (183330-62333918, default 184320): 183330
): t sector, +/-sectors or +/-size{K,M,G,T,P} (183330-62333918, default 62332927)
Created a new partition 10 of type 'Linux filesystem' and of size 29.6 GiB.
Partition #10 contains a ext4 signature.
Do you want to remove the signature? [Y]es/[N]o: n
Save Changes
3.Enter the p command to view the new partition information, then use the w command to write and save the changes.

Expansion Completed
4.Use the resize2fs command to update the filesystem size, then reboot the device to complete the expansion.
resize2fs -f /dev/mmcblk0p10
