We have a goal to support the Pi 4 but it is far too early to comment on a date as we have not even gotten our Pi 4 units yet.
ROS image on Raspberry Pi 4?
I have my first PI4, it needs heat sinks and a fan so badly it is not funny. Other than that
I am in love with sbc’s once more, more power here than my laptop, woot, woot!!
There are no ROS images out, yet, but I am watching and hoping for one soon.
I am still waiting on my Pi4s to arrive 
If someone has both an Pi3 and Pi4, and is willing to do some testing, it would be greatly appreciated, and help the image come out faster.
I’ve got my pi4 and a pi3. How can I help?
Me too.
I did notice a problem that turned out to be : " As detailed by Tyler Ward, the Raspberry Pi 4 has a non-compliant USB-C charging port and doesn’t work with as many chargers as it should. Thanks to the open nature of Raspberry Pi (even the schematics are online!), Ward was able to discover that Raspberry Pi just didn’t design its USB-C port correctly. Two “CC” pins on a USB-C port are supposed to each get their own 5.1K ohms resistor, but Raspberry Pi came up with its own circuit design that allows them to share a single resistor. This is not a compliant design and breaks compatibility with some of the more powerful USB-C chargers out there." so some little things too look out for is a board revision with a spec-compliant charging port should be out sometime in the “next few months.”
If you would like to help out can you follow the instructions on Raspberry Pi image on Pi 3 A+?
But replace 20190215 with 20190620.
Basically you will boot into a Pi3, upgrade the kernel and firmware and then try to boot into a Pi4.
There are likely going to be issues with Wifi, but first we want to be able to boot 
Thanks

Okay great! I may be able to get to that this weekend. I will report back if I can get anything working.
I made the instructions a little bit easier. I pushed a new kernel and firmware to our testing apt repo, so you will not have to build it yourself.
On a Pi 3+, edit /etc/apt/sources.list.d/ubiquity-latest.list to have the following
deb https://packages.ubiquityrobotics.com/ubuntu/ubiquity xenial main
deb https://packages.ubiquityrobotics.com/ubuntu/ubiquity-testing xenial pi
Note how the pi component is now from ubiquity-testing.
Now you can run sudo apt update; sudo apt upgrade to update your packages.
Make sure that apt policy raspberrypi-kernel shows 1.20190620-1 as the installed version.
Now put your SD card into your Pi 4 and let me know what happens

we would like ros melodic on a RPI4 image, please.
thank you.
Okay! I did this last night. I wasn’t totally clear but it sounded like I didn’t need to do anything on the other page. I flashed a fresh instance of the latest image on https://downloads.ubiquityrobotics.com/pi.html, booted it on a Pi3B+ and got it on my wifi, replaced the contents of the apt sources file you mentioned with the two lines you shared, did apt update (which took 16 min!) and apt upgrade, and then confirmed that the apt policy shows that value as the installed version.
Then I shut down the Pi3B+, placed the SD card in the PI4, and powered on the Pi4. It did not appear on my network. I suppose I should hook it up to ethernet and see if its alive? I am getting micro HDMI adapters in the mail next week. I will try ethernet and see if I can get it online.
EDIT: Hey it boots and comes up on ethernet! Do you know how I can check out why wifi might not work? The command “ip a” shows only loopback and ethernet. No wifi.
I do see some things I can try on this page, but I’ll wait for your reply before trying stuff:
One thing I noticed is that my /boot/cmdline.txt is different from the one on that page. I can also compare my /boot directory to one on my normal pi4 sd card, but that is raspbian not ubuntu so I’m not sure if they should be the same anyway.
I also got this configuration to boot on my PI-4, congratulations! You rock.
You may be the very first to have a usable image. (Note. the only thing not running is the WIFI.)

Awesome! Yeah I suppose I can use this at work now if I just stick a wifi dongle in there until we get wifi working. I’m glad it worked for you too!
Awesome! Wifi not working was an expected outcome, it usually takes some extra tweaking to get wifi to work.
Can one of you post the entire output of dmesg? I suspect it is a missing firmware file, but I am not sure.
Thanks so much for your testing! My Pi’s will not be arriving until at least August 20th, so you are really helping speed up Pi 4 support.
Sure! Expand this thing below to get the dmesg output.

I tried that Raspberry Pi 4 Ubuntu 18.04.2 install guide but the Pi 4 never makes it pass initial boot up. It gets stuck after the SSH messages and gets stuck for several hours till indefinitely.
Regarding this Ubiquity Robotics image on Pi 4, are you guys saying I also need to purchase a Pi 3 B+, install the image on that board for initial boot up and move the SD card over to the Pi 4? like a transplant?? 
Ubiquity Robotics hasn’t tested that guide, nor do we endorse it in any way. If it works we would love to know, as it would be helpful in getting our image working.
The ‘transplant’ as you call it is a temporary measure to update the kernel while we sort out Pi 4 support. When we start to offer Pi 4 support, you will just be able to simply download the latest image and get it to work. Right now with the ‘transplant’ method everything seems to work except wifi, which I am still working on.
Can you verify my step by step instructions on how you got this to work? I’m still a bit cloudy on the process with the Pi 3 side of things and the updating two lines part.
Let me see if I get this straight:
- Download latest XZ image from: https://downloads.ubiquityrobotics.com/pi.html which is currently “06-19” at the moment
- Unzip the XZ image into IMG using 7zip
- Etch the IMG file onto formatted SD Card
- Insert SD Card into a Raspberry Pi 3 board to do initial boot up
- On Pi 3 modify a file using: sudo nano /etc/apt/sources.list.d/ubiquity-latest.list by appending the following:
deb …packages.ubiquityrobotics.com/ubuntu/ubiquity xenial main
deb …packages.ubiquityrobotics.com/ubuntu/ubiquity-testing xenial pi
sudo apt-get update
sudo apt-get upgrade
sudo apt-cache policy raspberrypi-kernel -> Verify that it says “1.20190620-1”
7) Insert SD card into Raspberry Pi 4
Yes that is what you would need to do right now. Unless you absolutely have to I wouldn’t say I recommend it at the moment.
