How to attach new MIPI DSI display to iMX8QXP target board

[Rayn_Jang]

Hello,

I have to attach new MIPI DSI display to iMX8QXP target board and run android on this display.

In the imx8qxp mek board, there is no MIPI-DSI LCD Panel directly connected to the mipi-dsi port.

If you send the related modification files to attach a new MIPI-DSI display, we will check on our target board.(related modification files : device tree file, kernel config, mipi-dsi driver, etc.)

And we will send you our schematic with mipi-dsi display.

I’am using:

CPU : IMX8QXP

Android BSP Version : imx-android-10.0.0_2.5.0

MIPI-DSI Display : TOVIS-LI500HZ1AK( 720(H) * 1280(V), Display Color 16.7M )

Display panel also contain touch.

Hi Ryan

as android-10.0.0_2.5.0 is based on L5.4.47_2.2.0 kernel one can use rm67191 example:

https://patchwork.kernel.org/project/dri-devel/patch/1522751401-3381-2-git-send-email-robert.chiras@...

https://source.codeaurora.org/external/imx/linux-imx/tree/arch/arm64/boot/dts/freescale/imx8qxp-mek-...

for custom lcd change timings in struct drm_display_mode default_mode and initialization sequence

in struct cmd_set_entry manufacturer_cmd_set[]

Hi igor

after applying as your guide,

rad_panel_probe function is not called in panel-raydium-rm67191.c file.

What should I check?

Hi Igor

When debugging,
In the drm_mipi_dsi.c file, the mipi_dsi_drv_probe function is not called after the mipi_dsi_driver_register_full function is called.

When can I get an answer from you?
