recalbox not work well with DPI LCD on 4B

[ian57]

@DRAgon734235 quite strange... works well here...
perhaps it comes from the 7.2 beta ... so wait and see

@ian57
it is possible to rotate the DPI or HDMI LCD with 90 or 270 at recalbox 4B？

[ian57]

@DRAgon734235 actually with recalbox, no, sorry

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.

[proplayer2020]

Same issue on pi3... please help
or should I start new topic?

[proplayer2020]

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 ?

[Nanaki]

@proplayer2020 Hi, can you please provide information about your screen ? Brand, model, etc

Thank you

[proplayer2020]

sorry for late response, yes my recalbox works on tv screen.

[proplayer2020]

@Nanaki Its an adafruit 3,5" touch screen that connect directly to the rpi via spi bus

@proplayer2020

Hello, did you follow this link on Recalbox Wiki ?
https://wiki.recalbox.com/en/tutorials/video/tft/tft-lcd-on-spi-bus

[proplayer2020]

@Magaki Yes its the tutorial i followed.I followed the 2,8 inch screen part and I replaced dtoverlay by the same driver but in place of 28 i put 35

[proplayer2020]

Uhh... what is the difference between spi or dpi bus???
Do my screen might work on dpi bus?

[proplayer2020]

Exact reference of my screen :

seems to be pi tft PLUS and not pitft xd

This guide was prepared with this product :
https://www.adafruit.com/product/1601

I can't ensure you the guide could work with any DPI LCD, and don't think you can rename 28 to 35 for working it.

If you tried and it's not working, no more clues for help.

Hi, I have trouble with the setup of Recalbox with the official DPI LCD screen.
The screen runs perfectly well with other OS.
I have modified the config.txt adding the Adafruit screen configuration lines as the manual says.
I tried the fkms method and doesnt work neither.
What can i do to setup it up correctly?
Thanks
