Ok, here is the current setup:
– Installed Raspbian Jessie
– Installed RetroPi on top
– Installed drivers for LCD screen
Now when the Raspberry boots to RetroPi it shows the picture on the HDMP. However when i go to startx in the terminal it loads Jessie on the LCD screen..
Is there possibility to redirect the picture of RetroPi from HDMI to the LCD?ts87Participant03/02/2016 at 19:41Post count: 9
What do you mean? I installed Fbcp like that:
sudo apt-get install cmake git clone https://github.com/tasanakorn/rpi-fbcp cd rpi-fbcp/ mkdir build cd build/ cmake .. make sudo install fbcp /usr/local/bin/fbcp
and still the same – EmulationStation loads on the HDMI instead of LCD.herbfargusMember03/02/2016 at 21:07Post count: 1858
Does it show on the LCD when not plugged into HDMI? Might be a setting in config.txt that you can mess with. I think I did something with the HDMI configs but it was a long time ago so I don’t remember exactly.ts87Participant03/02/2016 at 21:21Post count: 9
I did check the file /boot/config.txt and i did set the following:
hdmi_cvt 320 240 60 1 0 0 0
however still no result..
Great, played a little bit too much with it.. Now it’s not booting, only white screen – time to reinstall the SD card..ts87Participant03/03/2016 at 10:36Post count: 9
I messed with the config.txt some more. I managed to rotate the LCD screen to the direction i actually needed (EmulationStation still boots on HDMI).
Few notes that might help:
When i set my Raspian Jessie to load on LCD it changes the /boot/config.txt by adding
I check the file /usr/share/X11/xorg.conf.d/99-fbturbo.conf
and i see output is set to /dev/fb1
From what i have seen online so far all should be fine.. but the fact is EmulationStation loads on the hdmi :(
I think i need to modify /opt/retropie/supplementary/runcommand/runcommand.sh by adding something like this:
mode_new = “DMT-87”
on function get_mode()
Unfortunately i don’t see such function in that file..herbfargusMember03/03/2016 at 10:56Post count: 1858
Did you edit the cmdline.txt at all? I had to add fbcon10 or something like that
My notes for my build are on this page:https://www.petrockblock.com/forums/topic/gamepi-zero-attachment-fileimage-jpeg/ may differ slightly from your hardwarets87Participant03/05/2016 at 19:25Post count: 9
@herbfargus thank you kindly!
So i re-installed Jessie.
Then i installed the LCD driver.
Next i installed RetroPie.
RetroPie shows on HDMI.
Switch to LCD terminal.
sudo raspi-config expand filesystem disable overscan force audio to 3.5mm advanced options >> enable Device Tree advanced options >> enable SPI >> load SPI kernel module by default sudo reboot
sudo apt-get install cmake git clone https://github.com/tasanakorn/rpi-fbcp cd rpi-fbcp/ mkdir build cd build/ cmake .. make sudo mkdir /usr/local/bin sudo install fbcp /usr/local/bin/fbcp
on its own on the second line before emulationstation is called.
sudo nano /boot/config.txt hdmi_force_hotplug=1 hdmi_cvt=320 240 60 1 0 0 0 hdmi_group=2 hdmi_mode=87
sudo nano /home/pi/emulationstation.sh
#!/bin/bash /usr/bin/local/fbcp & emulationstation sudo chmod +x emulationstation.sh
Not sure if the last one did anything, but after reboot RetroPie loaded on the LCD :)senkunParticipant03/14/2016 at 07:52Post count: 35
Then i installed the LCD driver.
Thank you for the step-by-step, I presume you’re using a 3.2″ lcd from WaveShare? May I ask what is that LCD driver that you installed in the second step right after installing Jessie?
