i.MX 8mp EVK OLED1A

[YuriiA07]

Is prebuild demo linux 5.15.32 support OLED1A?

I flash microSD by command
sudo dd if=imx-image-full-imx8mpevk.wic of=/dev/sdb bs=1M status=progress

put boot switch in right order.

In u-boot set:
setenv fdt_file imx8mp-evk-rm67199.dtb
run bootcmd

OLED1A is black....

you should set to fdtfile not fdt_file, then don't forget saveenv after setenv
