Using a custom device tree file

[Rainer Dorsch <ml@bokomoko.de>]

Hello,

I try to use a custom device tree file, but uEnv.txt does not have any effect:

rd@mohot:~$ cat /boot/uEnv.txt 
fdtfile=imx6dl-hummingboard-spi.dtb
rd@mohot:~$ fdtdump /boot/dtbs/4.14.0-3-armmp/imx6dl-hummingboard-spi.dtb|grep 
model

**** fdtdump is a low-level debugging tool, not meant for general use.
**** If you want to decompile a dtb, you probably want
****     dtc -I dtb -O dts <filename>

    model = "SolidRun HummingBoard Solo/DualLite SPI enabled";
        model = "On-board Codec";
        model = "On-board SPDIF";
rd@mohot:~$ cat /proc/device-tree/model 
SolidRun HummingBoard Dual/Quadrd@mohot:~$

Do I need to run flash-kernel or something else that uEnv.txt has any effect?

Thanks
Rainer
