Hi @Kunal , assuming you meant this link as the mini document, DART-MX8M : NXP i.MX8M, you shouldn’t need to do anything to connect it. That link uses the mender-convert utility which sets up your target image to connect automatically, assuming you have the rootfs_overlay setup properly. It will show up in the “Pending” tab under “Devices”.
The link on the dashboard to connect a device is for quick onboarding and testing with stock OS images and should not be used with mender-convert.
