New Raspberry Pi Image! Works on Pi 3B+ and A+

Hi all,

I have just put a new Raspberry Pi image into the folder at https://public.robotical.io/index.html?prefix=raspberry-pi-img/, robotical-pi-2018-12-04a.img.zip.

Main updates are:

The new WiFi script means that the Pi will try to connect to the WiFi networks defined in /etc/wpa_supplicant/wpa_supplicant.conf, and if it can't connect to a network it will output it's own WiFI hotspot. You can connect to that hotspot with the password raspberry

Once you're connected to the hotspot, the IP of the Pi will be 172.24.1.1, as before with our images.

If you want to VNC or SSH in to the Pi, the username is pi and the password is marty

I'm going to be converted my old blog post on Ball following with a Raspberry Pi and a camera and turning it into an article over the next few days, and extending it to get Marty walking more quickly to the ball in kicking it into a goal

If you've not had a Raspberry Pi in your Marty before, look here for some instructions on how to plug it in, and here for some info on getting connected over VNC viewer.

This image is designed to fit on a 16GB microSD card. To get started:

Note :- Installing a Pi into Marty will mean that it takes over high level control. To prevent confusion this will stop other control methods like Scratch and the remote control from functioning, but you can get Python running on the Pi and have everything running completely autonomously!

I've tested this on a Pi 3B+, A+, and on a 3B, and it's worked so far. As always, please do let me know how you get on with trying this out!

Sandy

Hello, the new image has ROS kinetic, OpenCV, and a few other things already on it - so it might not be too bad to make the switch? Having said that, I know how long it took me to get all that built (and all the ROS dependencies) sorted on a Raspberry Pi image, so things are rarely that simple.

I actually started from scratch with this image, I have a script that will do most of the set up from vanilla raspian, but I don't have an update script from the previous image I'm afraid. The set up script needs a bit of testing before it could be shown off, but I can go through what it does if that would help? You could try cloning your card and then just updating raspian, but I'm not sure what else that would break - at the very least you'd probably need to re-set the bluetooth/serial overlay to get the serial port working properly

Hi..I've got a bunch of tools on my image (ROS etc) that would take a day or more to rebuild and set up. Rather than do that, is there a change I can make to my existing image that will make the new board happy and still work with the old ones? What was done to make Stretch 3A+ compatible?
