iMX6ULL BSP Porting for 24bits LCD RGB888 parallel interface display

[文东陈]

Hello,

we need to port the imx6ull linux BSP to a custom board based mainly on imx6ull evk.

Our board includes a 24bit RGB88 TFT display with a LG LG4573A controller (see attachment).

Questions:

1) Is It sufficient to modify the device tree file imx6ull-14x14-evk.dts to make the display work?

2) Can anyone has an example to follow to modify the dts for these type of displays?

3) We Need to modify other source files in the BSP? Examples?

We are working with the following BSP version: fsl-yocto-L4.1.15_2.0.0-ga.

Thanks in advance for any helpful answer.

Best Regards,

winton.

You can suggest the customer to try "if=RGB24,bpp=16" and "if=RGB24,bpp=24" in the uboot command,

in the source code, one should change "board-mx6q_sabresd.c", the structure " ipuv3_fb_platform_data sabresd_fb_data[]" and "mxc_lcdif.c", the paramer depends on your display data sheet, we don't have sample code for your display, but one can refer to the source code and change it according to your display data sheet.
