SD FDisk

pi@bpi-iot-ros-ai:~$ sudo fdisk /dev/mmcblk0

Welcome to fdisk (util-linux 2.27.1).
Changes will remain in memory only, until you decide to write them.
Be careful before using the write command.


Command (m for help): p
Disk /dev/mmcblk0: 14.9 GiB, 15931539456 bytes, 31116288 sectors
Units: sectors of 1 * 512 = 512 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes
Disklabel type: dos
Disk identifier: 0x540302a1

Device         Boot  Start      End  Sectors  Size Id Type

/dev/mmcblk0p2      729088 15267839 14538752    7G 83 Linux

Command (m for help): d
Partition number (1,2, default 2): 2

Partition 2 has been deleted.

Command (m for help): n
Partition type
   p   primary (1 primary, 0 extended, 3 free)
   e   extended (container for logical partitions)
Select (default p): p
Partition number (2-4, default 2): 2
First sector (2048-31116287, default 2048): 729088
Last sector, +sectors or +size{K,M,G,T,P} (729088-31116287, default 31116287): 

Created a new partition 2 of type 'Linux' and of size 14.5 GiB.

Command (m for help): w
The partition table has been altered.
Calling ioctl() to re-read partition table.
Re-reading the partition table failed.: Device or resource busy

The kernel still uses the old table. The new table will be used at the next reboot or after you run partprobe(8) or kpartx(8).

PWM 관련 오류가 있어 수정해 보려고 했으나 포기

val pwmWrite 0 <= X <= 1024
Or you can set new range by yourself by pwmSetRange(range
