I am working on a little project but ran into some trouble and cant figure out how to fix it. I recently bought a waveshare 3.2" screen from ebay and it works, but not the way I want it to. I am making a portable raspberry pi with the OS retropie. But the problem is, When I start up the raspberry, it shows me the OS's menu on hdmi, but not on the tft screen. On the tft it only shows the desktop of raspbian, the OS retropie is based on. So basicaly what I want is that I can force the HDMI through the TFT, is this possible? Any other suggestions? Pls help

  • What do you mean by the OS menu? The OS Retropie's so called "raspi-config" or the so called "start menu"? – NULL May 27 '15 at 18:53
  • I dont mean the raspi config menu, I mean the actual OS, what you get when it starts up – Tobias Brugel May 27 '15 at 19:10
  • So, it is loading different OS to the different screens? What do you mean different OS's. See answer below for some ideas though. – NULL May 27 '15 at 19:13
  • Retropie is a OS which runs on Raspbian. Like 2 OS's in one. But if you start the raspberry up it will just inmidiatly launch retropie asplashscreen. This is how I want it to be. But on the tft it doesnt launch the retropie asplashscreen, it launches the raspbian desktop. – Tobias Brugel May 27 '15 at 19:16
  • Ok...great! Then see my answer below for some help hopefully. :-) – NULL May 27 '15 at 19:18

If I understand your problem you want to get to raspi-config. Open a LX-Terminal and type sudo raspi-config. This will bring you to the configuration menu. Otherwise, see below.

If you are talking about the "asplashscreen" try this. Navigate here:sudo nano /etc/init.d/asplashscreen and look for the do_start() function. Then insert as the first line in the function: /usr/local/bin/fbcp &.

Possibly, you could change these to fix your problem in config.txt.

hdmi_force_hotplug=1
hdmi_cvt=320 240 60 1 0 0 0
hdmi_group=2
hdmi_mode=87
dtoverlay=pitft28r,rotate=90,speed=80000000,fps=60

For more configuration that might help and more explanation, see this post by Adafruit about Retropie and touchscreens. Hope that helps!
