How can I configure my resinified raspberry for a touchscreen use?

Hi there

I want to use a little screen with my raspberry, but I need to set the size correctly.
I should enter this into a config.txt

Full documentation on this:

# uncomment if you get no picture on HDMI for a default "safe" mode

# uncomment this if your display has a black border of unused pixels visible
# and your display can output without overscan

# uncomment the following to adjust overscan. Use positive numbers if console
# goes off screen, and negative if there is too much border

# uncomment to force a console size. By default it will be display's size minus
# overscan.

# uncomment if hdmi display is not detected and composite is being output

# uncomment to force a specific HDMI mode (here we are forcing 800x480!)
hdmi_cvt=800 480 60 6 0 0 0

# uncomment to force a HDMI mode rather than DVI. This can make audio work in
# DMT (computer monitor) modes

# uncomment to increase signal to HDMI, if you have interference, blanking, or
# no display

# uncomment for composite PAL

#uncomment to overclock the arm. 700 MHz is the default.

# for more options see

I just pushed this config.txt to the raspberry via resin. But it does not change anything. Is this even the correct config.txt?
Or where does it have to go?

Additionally: I want to force the raspberry to output Audio via the 3.5mm Jack and not via HDMI. Normally I would just use raspi-config on normal raspberry, but on a resinified raspberry I am not able to do that.

Thanks in advance



-------- Edit:

I think I acutally managed to force audio to the jack instead of HDMI by adding

amixer cset numid=3 1

to the config.txt file. So I assume the raspi-config is only available by writing the flags into the config.txt.

But anyway, I still did not manage to get the screen to work… If someone sees an important thing I am overseeing, please feel free to tell me :).

Does this blog post help?

I’ll try some things. Thanks for the link so far. I’ll keep you posted if I achieve what I want.
