I’ve tried converting a raw disk image created using dd from a sdcard of a orange-pi running (almost stock) armbian but mender-convert-extract seems to think it’s a single fat32 filesystem:

```
$ MENDER_ARTIFACT_NAME=convert-1 ./mender-convert --disk-image input/central.img --config configs/raspberrypi3_config --overlay rootfs_overlay_demo/
Running mender-convert-extract: --disk-image input/central.img --config configs/raspberrypi3_config --overlay rootfs_overlay_demo/

```

Tried using both docker and non docker versions of the readme but got the same output.

Can you share output of `fdisk -l input/central.img`? This represents more what the `mender-convert` tool is looking at.

Makes sense yeah

```
$ fdisk -l input/central.img

Curious if you got it working on orange-pi with Armbian?

Just wondering if you have any further issues or if everything is working as expected?

Ah, I see. We’ve been trying to get a PoC running with [OrangePi Zero](https://hub.mender.io/t/orangepi-zero/142) since the convert tool doesn’t appear to support extented partitions, and that’s what our armbian install uses.
