Select peripherals support and display (sm2s-imx8plus)#

To configure those you’ll find on your SDCard a file called uEnv.txt that will hold any custom u-boot setting.

To change the peripheral support settings add or change the line

fdt_overlay=<overlay 1> <overlay 2>...

for example

fdt_overlay=overlay-baseboard-ep5.dtb overlay-lvds-ama-101a01.dtb

would activate support for EP5 carrier board and an AMA101(A01) display. The file can be edited with any ordinary text editor on your computer.
