Hyperpixel 4.0 not work at all


#1

So I bought a hyperpixel 4.0 not that long ago for a project and when I downloaded the software for it worked perfectly but now I tried to download the software again en it failed, I have tried this multiple times and it is not working at all I have almost everything can somebody please help me?


#2

Could you be more specific, is it the software download that’s failing, or the screen after the fact? What steps are you using to install the software, what errors - if any - do you see?


#3

so I’ve downloaded it successfully on with no errors on multiple raspberry pi’s but the screen wouldn’t be working so i think it’s the screen that’s not working but i can’t understand why


#4

Are you able to access the Pi (via SSH or otherwise) and look at the output of dmesg and also the contents of /boot/config.txt? Are you sure you’re downloading the hyperpixel4 code and not the hyperpixel code, also?


#5

I am able to access the pi with SSH normally and the`/boot/config.txt file is as following

# uncomment if you get no picture on HDMI for a default “safe” mode
#hdmi_safe=1

# uncomment this if your display has a black border of unused pixels visible
# and your display can output without overscan
disable_overscan=0

# uncomment the following to adjust overscan. Use positive numbers if console
# goes off screen, and negative if there is too much border
#overscan_left=16
#overscan_right=16
#overscan_top=16
#overscan_bottom=16

# uncomment to force a console size. By default it will be display’s size minus
# overscan.
#framebuffer_width=1280
#framebuffer_height=720

# uncomment if hdmi display is not detected and composite is being output
hdmi_force_hotplug=1

# uncomment to force a specific HDMI mode (this will force VGA)
hdmi_group=1
hdmi_mode=4

# uncomment to force a HDMI mode rather than DVI. This can make audio work in
# DMT (computer monitor) modes
hdmi_drive=2

# uncomment to increase signal to HDMI, if you have interference, blanking, or
# no display
#config_hdmi_boost=4

# uncomment for composite PAL
#sdtv_mode=2

#uncomment to overclock the arm. 700 MHz is the default.
gpu_mem=400
arm_freq=1350
over_voltage=5
sdram_freq=500
core_freq=500
gpu_freq=400

# Uncomment some or all of these to enable the optional hardware interfaces
#dtparam=i2c_arm=on
#dtparam=i2s=on
#dtparam=spi=on

# Uncomment this to enable the lirc-rpi module
#dtoverlay=lirc-rpi

# Enable audio (loads snd_bcm2835)
dtparam=audio=on
gpu_mem_256=128
gpu_mem_512=256
gpu_mem_1024=256
#overscan_scale=1
dtoverlay=hyperpixel4
overscan_left=0
overscan_right=0
overscan_top=0
overscan_bottom=0
framebuffer_width=800
framebuffer_height=480
enable_dpi_lcd=1
display_default_lcd=1
dpi_group=2

hdmi_timings=480 0 10 16 59 800 0 15 113 15 0 0 0 60 0 32000000 6

and I installed it with the one line download, the GitHub installer and by downloading the master file from GitHub putting it in the sd card in the right location and then unzipping it from the terminal


#6

Are you sure you’ve got a HyperPixel 4, and not the previous model?


#7

yes I did have the hyperpixel 4 but it doesn’t matter anymore i’ve already returned it I think it just stopped working,
still thanks for your help
