Waveshare 12287 not working with retropie

Zed

Hi Guys,
I've searched, but can't deal with it. I have a Waveshare 12287 installed on GPIO, but can't get it to work with retropie.
Here's my config: https://pastebin.com/DAUgtnzs
I would appreciate any advice.
Thanks!

What PI model is this ?
How did you install/what software did you run to install the display ? What exactly doesn't work means - you get no display, games don't start, the front-end doesn't start, etc. ?

RPi 4b 8gb
I install Retropie from Raspberry pi imager
The emulation station isn't launching.

If it's a Pi4, then the configuration is wrong, since the GPU drivers are disabled. The hdmi_cvt option is missing the = sign. This is not the default config.txt shipped by RetroPie, so you probably run an 'installation script' for the Waveshare.

You current config shows:

...

[pi4]
# Enable DRM VC4 V3D driver on top of the dispmanx display stack
#dtoverlay=vc4-fkms-v3d
max_framebuffers=2
dpi_timings=1024 1 40 48 128 600 1 13 3 45 0 0 0 60 0 37000000 6
 
[all]
#dtoverlay=vc4-fkms-v3d
dtoverlay=dpi24
enable_dpi_lcd=1
display_default_lcd=1
dpi_group=2
dpi_mode=87
dpi_output_format=0x6f005
hdmi_cvt 1024 600 60 6 0 0 0
disable_overscan=1

Try to replace the lines above (leaving the other options intact) with:

[pi4]
# Enable DRM VC4 V3D driver on top of the dispmanx display stack
dtoverlay=vc4-fkms-v3d
dtoverlay=dpi24
dpi_output_format=0x6f005
max_framebuffers=1
enable_dpi_lcd=1
display_default_lcd=1
hdmi_cvt=1024 600 60 6 0 0 0
[all]
disable_overscan=1

@mitu Thanks! I will give it a go and get back to you :-)
