You can create a bootable microSD card image and use it to boot the ConnectCore 6 Plus.

Generate the image for the microSD card

To build an image that can boot from the microSD card:

  1. Add the following to your project’s conf/local.conf file:

    conf/local.conf
    IMAGE_FSTYPES:append = " wic.bmap wic.gz"
    Note the required white space when appending a value to an array variable using the :append override syntax.

  2. Build your image recipe, for instance:

    $ source dey-setup-environment
$ bitbake dey-image-qt

This creates a compressed image file in your project’s deploy directory with the extension .wic.gz, along with the block map file with extension .wic.bmap.

A .bmap file (short for block map) is a metadata file that describes which blocks in a disk image (e.g., .wic) actually contain data. The bmaptool utility uses this file to copy the image to an SD card faster and more efficiently.

Refer to Boot from microSD card for instructions on programming the image on the microSD card and preparing your target to boot from it.
