4. How to use this package

4.1. How to write the SD Card Image into the SD Card

  1. Copy the following files into any directory on the Linux PC.
    • rzv2h_ai_performance_demo_***_camera_sd_image.wic.gz
  2. Execute the following command to install bmap-tools into the Linux PC. (If already installed, this step can be skipped.)
$ sudo apt install bmap-tools
  1. Insert the micro SD Card into the micro SD Card reader, and connect the micro SD Card reader to the Linux PC.
  2. Execute lsblk command, and confirm the device file name of the micro SD Card and the size of it.
    • In this example below, the device file name of the micro SD Card is sda listed on the NAME column.
$ lsblk
NAME        MAJ:MIN RM   SIZE RO TYPE MOUNTPOINT
:
sda           8:0    1  14.2G  0 disk
├─sda1        8:1    1  16.9M  0 part
└─sda2        8:2    1     4G  0 part /mnt/sd
:
$ sudo umount /dev/sda2
or
$ sudo umount /mnt/sd
  1. Write the SD Card image file (rzv2h_ai_performance_demo_***_camera_sd_image.wic.gz) into the micro SD card by the following command.
    • The command below writes the SD Card image to the sda device file. Please replace sda with a device file name displayed on your Linux PC by lsblk command.
$ sudo bmaptool copy --nobmap rzv2h_ai_performance_demo_***_camera_sd_image.wic.gz /dev/sda

Note: It will take approximately 5 minutes to write the image file to the SD card.
