Changing to Raspberry Pi 4 Model B

Posted by: chrisbuy

Anyone busy with that? I had a small issue with my Raspberry Pi 3 Model B in A.bo when soldering so I 'have' to replace the Raspberry Pi. Why not upgrade at the same place? The form factor remains the same, the GPIO remains the same, the Raspian OS remains the same (although slightly newer) and the price of the Raspberry Pi remains with reasonable limits (40 - 60 EURO)!

Feel free to contact me to exchange ideas but expect more info from me when I finally receive (end of July 2019) my Raspberry Pi 4 Model B... 

Hi Chris,

yes, i am trying to configure Rpi4 ( i have one ;) with Q.bo. I had some issues with Raspbian but the rest works fine. Feel free contact me if you need more info about it.

Very lucky you got already to the Rapberry Pi 4... I took the 4GB model but obvious weeks delay... :-(

Good to hear it works... Okay, I suspect Raspian will be the challenge... Thanks!

Okay, I've got hold of Raspberry Pi 4. 

But only the WiFiSearchQR.sh and the Django website on 8000 works! 

I got by the libttspico-utils issue not being available anymore by default with Raspian Buster but I get no audio.

"aplay -l" gives me...

* List of PLAYBACK Hardware Devices *

And only "aplay -D hw:0,0 /opt/qbo/sounds/blip_0.wav works via the audiojack. hw:1,0 does not exist while the driver seemed to load.

How did you get sound working? 

I certainly would like to see it working fully with Raspberry Pi 4B. That device is a real beast - much more onboard memory faster processor and much more. Not to mention better connectivity compared to Raspberry Pi 3.

I've managed to get a basic Q.bo setup (Dialogflow) to run on a Raspberry Pi 4B, Raspbian Buster, Python 3.7 and OpenCV 4.1.1... BUT NO AUDIO (MIC/SPEAKER) YET! :-( I CAN'T GET THE DRIVER WORKING ALTHOUGH I REPLACED IT WITH AN UPDATED DRIVER. I AM ASSUMING A CURRENT KERNEL ISSUE WITH RASPBIAN BUSTER.

1. Replace the existing Raspberry Pi with Raspberry Pi Model 4B
2. Install a basic Raspbian Buster with SSH access
3. Download the attached QBO_Installer_pi4_10.sh
4. Make it executable and run 'sudo QBO_Installer_pi4_10.sh
5. Answer the typical questions but primarily WAIT. It takes a few hours!
6. Edit /opt/qbo/PiFaceFast.py and comment out any line with StartHotWordListener or StopHotWordListener

Hi Chris,

As you know, the Raspberry Pi is equipped with one SPI bus that has 2 chip selects.

You can find all the "official" information here:

https://www.raspberrypi.org/documentation/hardware/raspberrypi/spi/README.md

My qbo has been sitting on the shelf while I've been busy with other stuff.  I will be ordering the  Raspberry Pi 4B tonight.  

Has anyone found the Scratch v3 version more useful?

I am picking this again up. Has anyone succeeded in getting the Raspberry Pi 4B working with Qbo? Please contact me or reply... I am at a loss! 

Much, much appreciated! It would be my best Christmas gift... ;-)

Hi Chris, if I'm not mistaken, on July 28, 2019, you did an amazon review for Qbo, in which you said you installed the raspy pi4 Model B, did you progress in the compatibility test? Qbo works with pi4? Thanks for the reply.

@romeo Hi Romeo,

what problem did you have to use Rpi4 with Q.bo One?.
