Raspberry PI 4 + LS055R1SX03

I have an RP4 at home, I ordered the LS055R1SX03 display for it. I am able to set the display before loading Nanodlp

config.txt

#slight overclock
gpu_freq=500
over_voltage=2

#more gpu mem, 64 is std
gpu_mem=256

#ignore any hdmi mode from display
hdmi_ignore_edid=0xa5000080

#Always put out on hdmi
hdmi_force_hotplug=1

#custom hdmi mode
hdmi_group=2
hdmi_mode=87

#DVI mode, no audio output
hdmi_drive=1

#up the freq limit above std
hdmi_pixel_freq_limit=204792000

#timing of the display
hdmi_timings=1440 1 70 35 45 2560 1 12 2 2 0 0 0 50 0 204792000 3

#Overscan settings
#overscan_left=0
#overscan_right=0
#overscan_top=0
#overscan_bottom=0
#overscan_scale=1
disable_overscan=1

#framebuffer settings
framebuffer_width=1440
framebuffer_height=2560
max_framebuffer_width=1440
max_framebuffer_height=2560

#framebuffer_depth=8
#framebuffer_depth=24
#framebuffer_depth=32
#framebuffer_ignore_alpha=1

hvs_priority=0x32ff

display_hdmi_rotate=0

when I insert these values into a clean RP the display shows beautifully. I put the command via putty: (wget (I had to delete the link) --no-check-certificate -O - | tar -C / home / pi -xz --warning = no-timestamp) ; cd / home / pi / printer; sudo ./setup.sh

I'm going through the installation process, the device restarts and then I'm no longer able to bring the display to life in any way.
I also tried the beta version of nanodlp, but it's still the same.

Re: Raspberry PI 4 + LS055R1SX03

Are you using default SD image from nanodlp site? Are you sure you are using raspbian lite?

Re: Raspberry PI 4 + LS055R1SX03

I tried raspbian lite + nanodlp and raspbian from nanodlp

I spent a lot of time searching and trying but no result

RP communicates but does not show I do not know where to look for a bug

I have another knowledge I changed hdmi_timings to: hdmi_timings = 1440 0 16 16 64 2560 0 5 2 1 0 0 0 50 0 200000000 3 and when loading the RPD the CMD is displayed after loading nothing else

Re: Raspberry PI 4 + LS055R1SX03

finally i tried different settings and the display works.
config.txt

#Use HDMI
hdmi_force_hotplug=1
#define mode 87
hdmi_timings=1440 0 60 10 35 2560 0 4 2 2 0 0 0 50 0 198000000 0
#force mode
hdmi_group=2
hdmi_mode=87
hdmi_pixel_freq_limit=500000000
hvs_priority=0x32ff
max_framebuffer_width=1440
max_framebuffer_height=2560
framebuffer_width=1440
framebuffer_height=2560
framebuffer_depth=24
framebuffer_ignore_alpha=1
config_hdmi_boost=4
gpu_mem=192

# Additional overlays and parameters are documented /boot/overlays/README
enable_uart=1
start_x=1
hdmi_edid_file=1

console:

sudo /opt/vc/bin/tvservice -d /boot/edid.dat

but only the calibration works when I give the print nothing appears on the display

Re: Raspberry PI 4 + LS055R1SX03

If calibration works other places also should work, it could not be config.txt related.

Re: Raspberry PI 4 + LS055R1SX03

I have no idea I'm a beginner.  I also find it interesting.  while the control panel to the display lights up that it is active, but it does not show anything.  when I give a sample it will display without any problems but the display is black when printed

What mode should the boot be in?
can't it be that I have a raspberry pi 4?

Re: Raspberry PI 4 + LS055R1SX03

No, route is the same. Does it move to second layer? (even without displaying)
Just start print after sometime get debug file (setup/tools/debug button) and share it.
