Frequently Asked Questions

1. My rootfs is too small, how to make it larger?

The BSP does not specify any storage size, so the rootfs will be just large enough to contain the content built by the yocto image. If you need to increase the size the size of the rootfs you can add the following to your local.conf:

IMAGE_ROOTFS_EXTRA_SPACE = "500000" # KBytes

IMAGE_ROOTFS_EXTRA_SPACE can be set to increase the amount of free disk space in the rootfs partition.

For more information you can check the Yocto Reference Manual.

2. My home partition is too small, how to make it larger?

You can set the home partition size by setting the following variable in your local.conf:

IMAGE_HOME_SIZE = "500M"

3. How to add additional applications to my image

If you want to add new applications to your image you can set the following variable in your local.conf:

IMAGE_INSTALL:append = " \
        gdb                  \
        htop                 \
"

The example above will add gdb and htop to the image that gets built by bitbake.

4. Connecting to the board by ssh over USB does not work on Windows

By default the BSP uses the USB gadget adb+rndis to provide both debug and network interface over USB. Install Google’s USB driver for adb interface, and Windows built-in rndis driver.

For more information you can check the Get the Google USB Driver.
