This project can help if you get a black screen when trying to start your Computer Kit.
For this project, you'll need a Windows of Mac computer with a memory card reader.
With your Computer Kit powered down, slide the micro card out of the back:
Now slide the micro card into the black adapter that came in the box:
Great! Next, insert the card into the memory card reader on your laptop or desktop computer.
Download & Install
We'll use a program called Etcher to write the software to the memory card. The website will automatically choose the right version for your computer:
Next, we'll grab a copy of the latest version of Kano OS:
The download for Kano OS is quite big, so while it's doing that, go ahead and open the the Etcher file and follow the on-screen instructions to install and run it.
Re-Install Kano OS
Open the Etcher program you installed a little earlier on. Click Select image:
Select the file you downloaded and click 'Open'.
Select the Kano OS file you downloaded and click Open:
The program should automatically detect your memory card and select it. If it has chosen the wrong one, just click the Change button to select the correct card (it should be 7.9 GB in size):
You're ready to go! Click Flash! (The computer may need your permission to access the memory card). It should take between 10-15 minutes to complete:
Etcher will have ejected your card, so you'll have to take it out and put it back in again at this stage.
We've created some special files that will tell your Computer Kit how to talk to your TV.
The first file will stop the computer using any other files:
The second file will tell the computer the resolution we want to use. Most TVs support 1080p, so this is the one we recommend to try first.
(Screen not 1080p? Take a look at the section below)
Head to your downloads folder and copy the two files onto your memory card. If you see a warning that a file already exists, go ahead and click replace:
It should then look something like this:
Safely eject the memory card from your computer, Then plug the card back into your Computer Kit, and you should be good to go!
Using a DVI Monitor?
If you are using a DVI adapter to connect to a monitor then you might need to remove your LED light ring from your kit's Raspberry Pi. This is because when the OS detects the light ring it thinks that it is supposed to send sound over the HDMI cable. These sound waves might cause trouble with your monitor!
The solution is easy...just remove your light ring and when you get to the OS Dashboard, go to the Settings page and change the audio output to be Analogue instead of HDMI. Now it should work fine with any DVI monitor!
TV not 1080p?
If your TV doesn't support 1080p, you can find the native resolution by doing a quick search online using your TV's model number. Simply download the file that matches your TV's settings and copy it onto the card the same way as shown in the previous steps.
Other common resolutions:
