Identify Your Module

Before you flash or communicate with the Signaloid C0-microSD, you need its device path on your host. An SD-interface module enumerates as an unformatted block-storage device. The C0-microSD appears as ~20.2 MB / 19.3 MiB.

warning

If your operating system prompts you to format the device, dismiss the prompt. Formatting corrupts the on-device data layout.

macOS

Run diskutil list and look for the small (~20 MB) disk:

% diskutil list
...
/dev/disk4 (internal, physical):
   #:                       TYPE NAME            SIZE       IDENTIFIER
   0:                                           *20.2 MB    disk4

Here the device is /dev/disk4.

Linux

Run lsblk and look for the ~19.3 MiB disk:

% lsblk
NAME   MAJ:MIN RM   SIZE RO TYPE MOUNTPOINTS
sda      8:0    0    64G  0 disk
├─sda1   8:1    0     1G  0 part /boot/efi
└─sda2   8:2    0  62.9G  0 part /
sdb      8:16   1  19.3M  0 disk

Here the device is /dev/sdb.

Windows

Run diskpart, then list disk, and identify the ~19 MB disk:

DISKPART> list disk
  Disk ###  Status         Size     Free     Dyn  Gpt
  --------  -------------  -------  -------  ---  ---
  Disk 0    Online          256 GB      0 B        *
  Disk 1    Online           19 MB      0 B

Access raw disks via \\.\PhysicalDriveN, where N is the disk number, here \\.\PhysicalDrive1.
