Device Tree Compiler missing option '-@' - SOLVED

[photomankc]

In trying to follow some of the device tree muxing examples I installed the 'dtc' package with pacman. The problem is that all the examples call out the option '-@' and the version that I have does not include this option. It appears that this is provided in a patch that is needed to make the blobs work with capemgr. It appears I either need to build dtc from source and patch it or hope that it gets patched and updated for pacman.

If I have to build from source then will I need to fetch all the kernel source to build this piece? I don't really follow the process on how to pull all the kernel sources yet. I don't yet get how you use abs, where to put things and so forth. Is there a good tutorial beyond the wiki?


Edit: This is the patch referred to - https://patchwork.kernel.org/patch/1934471/

Ok so I pulled in the source late last night using "makepkg --no-build" and this morning found that there was an already compiled "dtc" in the ./scripts/dtc/ directory now. Printing the help showed it understood the -@ symbol. Once my new .dtb was compiled with that I was able to boot with some extra ttys without clobbering the rest of the claimed pinmux settings:

/dev/ttyO0 /dev/ttyO1 /dev/ttyO2 /dev/ttyO5

I would love it if you would post how you got -@ working. I've been unable to figure it out thus far.

I copied the binary from /usr/bin/dtc on Angstrom and it seems to work. It also seems like a horrible way to do business, but I needs -@
