Using DTB-Overlay's

(Frank W.) #1


is there a way to use dtb-overlays? imho uboot supports dtb-overlays since v2017-x, but our uboot is 2014-x. maybe there is another way to load them, but i have nothing found about loading them after boot.

this can be used for SPI/i2c-devices…

regards Frank


Update uboot and add device tree support as the current version is out-of-date.

An related question is do you really need to do that in uboot?
