I am trying to configure a splashscreen in u-boot on an orange pi zero plus using Armbian.

 

The screen is connected through spi1 using the ST7789v chip of the LCD. I have successfully configured the screen when the kernel is loaded.

 

I already have used systemd to display a splashscreen however I find it slow to display something. It display something only after ~12 sec. I could probably reduce that time a bit by loading the service earlier but it would never start in 5 sec.

 

I have tried unsuccessfully to activate CONFIG_VIDEO_LCD_MODE (VIDEO_LCD_MODE) in u-boot which allow to configure an LCD. It seems that it is not allowed because it depends on !MACH_SUNXI_H3_H5.

 

How can I configure the output to the LCD via the SPI 1 ?

 

It seems that u-boot doesn't take in charge spi as a video output. I can see LCD, HDMI, DVI, VGA,... but no SPI. Is it possible to configure the SPI as LCD? Or to send framebuffer to the SPI to display the splashscreen?

Hello.
Did you succeed?

I'm also trying to figure out how to connect a spi lcd in U-Boot.
