Enabling 5" MIPI-DSI Panel

Introduction

This article shows you how to enable the 5" MIPI-DSI display panel on certain i.MX8M Mini Development kits.

This is really just a matter of selecting the correct device tree blob (.dtb) file to be loaded by U-boot during the boot-up sequence.

This is done in U-boot. In order to do this, reboot the board with a serial console attached, then halt the boot process using any key. The following instructions assume that you are doing this on the U-boot command line.

PICO-IMX8M-MINI:

On PICO-PI:

setenv fdt_file imx8mm-pico-pi-ili9881c.dtb
saveenv

FLEX-IMX8M-MINI:

On FLEX-PI:

setenv fdt_file imx8mm-flex-pi-ili9881c.dtb
saveenv
