@ian57
OK , I will test when recalbox 7.2 beta come .it is possible to rotate the DPI or HDMI LCD with 90 or 270 at recalbox 4B?

@DRAgon734235 no not yep... even with new 5.10 kernels
did you see this https://www.waveshare.com/wiki/2.8inch_DPI_LCD there are specific overlays for this screen https://www.waveshare.com/wiki/File:28DPIB_DTBO.zip
I think you should copy them in the /boot/overlays directory and use the config from the wiki :
gpio=0-9=a2 gpio=12-17=a2 gpio=20-25=a2 dtoverlay=dpi24 enable_dpi_lcd=1 display_default_lcd=1 extra_transpose_buffer=2 dpi_group=2 dpi_mode=87 dpi_output_format=0x7F216 hdmi_timings=480 0 26 16 10 640 0 25 10 15 0 0 0 60 0 32000000 1 #dtoverlay=waveshare-28dpi-3b-4b #dtoverlay=waveshare-28dpi-3b dtoverlay=waveshare-28dpi-4b

yes , I use that dtbo file from waveshare
I have tried that code , same
The LCD can display OK , but recalbox os can not enter Emulator
I think this is recalbox bug at DPI LCD,
-
@DRAgon734235 in the code you post, you use dpi18 and not dpi24 which is the right one
which one are you using?
-
-
@DRAgon734235 quite strange... works well here...
perhaps it comes from the 7.2 beta ... so wait and see -

Hello, i seen this post is quite old, but i have the same issue, even in recalbox latest version (8.11 or something).
But on recalbox latest version, i can rotate to 270 ad 90°,
but the screen stays on the logo screen like DRAgon734235's screen.
I think my screen is SPI but im unsure because im new to screen modes and all (but work like that with SPI and not works with DPI).I looked all the tutorials to connect TFT screen to rpi4 and yet doesnt works and stays the same loading screen.
Sorry for bad english.
-
Same issue on pi3... please help
or should I start new topic? -
I also think that the rpi doesn't detect the screen and just boot's up when i plug a TV hdmi.

@proplayer2020 hello
is your recalbox starts when connected to a hdmi tv ?
