As such it makes a good choice for an unattended headless device.
Unfortunately there is no Official Ubuntu image for the MQ Pro, but you can use the image for the Lichee RV dock. This has the same SOC as the MQ-Pro, and boots properly.

Once the LicheeRV image is booted you can swap the device tree it uses for the MQ-Pro one.
- Vanilla device trees for all current Risc-v platforms are provided as part of the firmware package for each kernel.
- This means that the mqpro device tree *is* available, but is not the default installed by `flash-kernel` for the image file we use.
- You can reconfigure `flash-kernel` with a different default device tree name in config
- You can reconfigure `flash-kernel` with a different default device tree name in config.
- This is future proof, each new kernel deliveres a new device tree that will be installed as the kernel is upgraded.
- The idea of compiling your own DT is depreciated in favor of the vanilla mqpro devicetree and using gpiod and pinctl to setup devices.

- However, I also have instructions for doing this, for those who like to tinker.

## Installing Ubuntu
There is *no* specific image provided by Ubuntu for the MQ PRO, but they *do* provide an image for the 'Sipeed Lichee RV' which installs and boots on the MQ Pro with almost everything working.
- I had issues getting a successful first boot with a cheap SD card, using a brand-name (Kingston) high speed card solved all the issues.
## Install Steps
If you have set up SD card based systems before the following should feel familiar. You will need a SD card to boot and run the system.
- I had issues getting a successful first boot with a *generic* cheap SD card, using a brand-name (Kingston) high speed card solved all the issues.
- I am also using a high wear resistance card since I want this to run for years in a hard-to-reach location.
You can boot the licheerv image directly on the MQ Pro, the HDMI console is available:
- Unfortunately it only starts very late in the boot process and is not usable until the boot is complete.
- You can use a USB keyboard, and install `gpm` to get a working mouse.
### Notes
Unfortunately HDMI only starts very late in the boot process, you cannot select GRUB options, and the console is not usable until the boot is complete.
- Once the console login is available You can use a USB keyboard with it, and install `gpm` to get a working mouse.
- Once I had bluetooth working I was able to attach and use a bluetooth kbd+mouse.
- If you have a USB serial adapter available you can follow the entire boot process
If you have a USB serial adapter available you can follow the entire boot process
- This is the only way to access the GRUB prompt and select recovery options etc!
- Make sure your adapter is set to 3.3v and *not* 5v. This is important.
- Attach `gnd`, `tx` and `rx` to pins 6,8 and 10 on th eGPIO header.
- See Jeff Geerlings excellent '[https://www.jeffgeerling.com/blog/2021/attaching-raspberry-pis-serial-console-uart-debugging](https://www.jeffgeerling.com/blog/2021/attaching-raspberry-pis-serial-console-uart-debugging) article for a good description. His example is for a Raspberry PI, but MQ Pro is *identical* to a Pi for this.

The WiFi module will be detected, but will not connect to any networks unless preconfigured on the SD card before first boot.
- The instructions below show how to do this. (Requires a linux machine to mount+modify the SD card.)
- Alternatively, wait for the console boot to finish and configure the network on that using netplan or NetworkManager.
- If you have a Linux compatible USB Ethernet adapter you can attach that to the spare USB-C port.

- Alternatively, wait for the console boot to finish and configure the network on that using netplan, this is also covered below.
If you have a Linux compatible USB Ethernet adapter you can attach that to the spare USB-C port on the MQ-Pro.
- It will be detected and connected (using DHCP) during boot.
- You will need to find the assigned IP from router logs, netscan, or looking on the console.
### Creating SD card & first boot.
### Creating SD card
You will need a suitable machine to download the image file to, with a SD card writer so the image can be written.
- The instructions below are for a generic Linux system with a sd card writer.
- As ever with this sort of operation make *absolutely* sure you are using the correct disk device when writing.
- The example here assumes `/dev/mmcblk0`, which is the inbuilt SD card slot om *my* system.
- The example here assumes `/dev/mmcblk0`, which is the inbuilt SD card slot onm *my* system. ymmv.
- Windows users need to ignore the linux steps and use a tool such as Belena Etcher or similar to burn the SD card, before skipping to [first boot](#first-boot).
Get the image file; (as of 2-Sep-2024 the url below works).

#### First Boot
### First Boot
Insert the SD card into the MQ Pro and BOOT.
- First boot is SLOW. It will take 5+ minutes before anything useful appears on HDMI.
- This is where, if you have a serial adapter, it is handy for following progress.

# My Motivation:
My MQ PRO is connected to a Waveshare LORA hat, I want to make it work but the default device tree conflicts with some of the pins my HAT uses. So I decided to 'fix' this by putting a better device tree on my board.
