Can't edit boot/config.txt
-
I plug my raspberry in and it does not show image only if I plug a usb flash drive in does it fire up
(Raspberry pie b) running latest version of retro and I use a 16 gb adata sd card

@bradleyhollander Brad, I would start from scratch, my friend. Also you need to tell us what it is you have done and are trying to do. We are not psychics.
-
Ok sorry I followed the official retropie setup 100% and I even did it again and nothing shows on screen when I switch the raspberry pi on. only when I use a hdmi screen does it work or if I plug a usb into the rasp pi
-
@bradleyhollander if you have no screen connected what should it show?
-
@bradleyhollander That is odd. I Would re-download the image and burn it again to a newly formatted SD card just to be sure. Sometimes stuff just goes wrong. Never assume anything!
-
Could it be my sd card because I have tryed formatting it and flashing the .img twice. but I'm still left with no image coming on when I plug in a screen and power into my pi
-
@bradleyhollander Is the green LED lighting up?
-
I will try again maby it works on try number 3
-
otherwise try another sd card
-
@bradleyhollander Before you do that, plug it in. Is the green LED flashing at all?
-
@AlexMurphy yes it flashes in quick succeshion
-
@bradleyhollander That means it is working. What sort of display is it connected to? Try a different TV or a different HDMI cable.
-
@bradleyhollander the power supply could also be a problem
use one with a minimum of 1A output -
@AlexMurphy I use a old Vga screen with a hdmi adapter
-
@bradleyhollander Your adaptor is not compatible, sorry.
-
Ok that is the problem
The vga adapter disables the hdmi auto detection of your monitor
this can be resolved somehow, let me look into my old pi, I made it there somehow -
Ok so what you have to do:
- connect via ssh over network (you need a console for this, however you get to it)
- type
sudo nano /boot/config.txt
- Remove the # in front of
hdmi_force_hotplug=1
- press ctrl+x, enter and than y,enter to save the file
- restart your pie with
sudo reboot
if you get no output:
Remove the # in front ofhdmi_safe=1
as well and reboot
Now the hdmi port is forced to be activated and outputting at any time.
This diables composite output, but I guess you don't want to use it.Hope that helps
-
Composit the yellow plug?
-
@bradleyhollander yeah, I guess that was it
