retropie and waveshare 32b?

tonaytan

@tonaytan so guys I made a guide maybe someone wants to look into that because GPIOnext needs some commands that need to be added https://retropie.org.uk/forum/topic/12176/pigrrl-button-installation-need-advise

According to this tutorial I only got a black screen. What is wrong?

Private messaging isn't an available feature on this forum.

Mr.Monkeyface

I have tried this over and over but once I get to sudo cp waveshare-dtoverlays/waveshare32b-overlay.dtb /boot/overlays/waveshare32b.dtbo it never works I have tried both commands and nothing works. Any ideas.

sorry for bumping this old topic, but i've just got the 3.2" waveshare screen for a gamegear project, but when i go to run the 2nd command after installing a fresh version of retropie:

sudo cp waveshare-dtoverlays/waveshare32b-overlay.dtb /boot/overlays/

I get the below message:

cp: cannot stat 'waveshare-dtoverlays/waveshare32b-overlay.dtb': No such file or directory

any ideas please?

cheers

You should look for updated instructions on how to install the screen - the repository mentioned in the instructions has been restructured and the filenames don't match. Look into the repository documentation at https://github.com/swkim01/waveshare-dtoverlays and install your screen.

sorry about that thank you for the update. all instructions followed and i've got the fb1 folder. when i add the extra lines in and then reboot... i'm still getting a white screen on the waveshare 3.2 but retropie is showing on my monitor
