Thanks. That's what I tried but I get an error.
dtc imx6dl-wandboard.dts -O dtb -o imx6dl-wandboard.dtb
Error: imx6dl-wandboard.dts:12.1-9 syntax error
FATAL ERROR: Unable to parse input tree
I googled this error and it says there is some new way to build dts files using make that resolves this error but I can not figure out how to do this.
In this test case I have not modified the imx6dl-wandboard.dts file and if I rebuild the kernel SRPM it builds fine.
I guess I want to know how the kernel SRPM builds these files.
