[U-Boot] dtc: invalid option -- 'i'
Hi List,
I am using a 64-bit ubuntu machine running a 12.04 LTS. I see that the DTC (Device Tree Compiler) version is 1.3.0
$ dtc -v Version: DTC 1.3.0
When I try to compile the latest u-boot 'master' branch (updated yesterday), I get the following error with dtc:
dtc: invalid option -- 'i'
followed by a Usage suggestion.
I checked that a newer DTC version 1.4.0 is available from Linaro, but I can't find an updated version for ubuntu and apt-get returns me a message:
device-tree-compiler is already the newest version
Any pointers to what I could be doing wrong here?
Regards, Bhupesh

What target are you building for as it should have run the 'checkdtc' rule and told you that you need to install DTC 1.4.0. And yes for Ubuntu you'll need to build your own.

Hi Tom,
I am trying to build the new support code of ARMv8 (using patches from David Fengua), using:
$ make vexpress_aemv8a
I will try building a DTC 1.4.0 for u-buntu by myself, but if we are saying that latest u-boot requires DTC 1.4.0 to work well, aren't we breaking u-boot compilation on older systems like ubuntu/fedora which have older DTC versions?
Regards, Bhupesh

Ah, OK, I'll make sure that it invokes the checkdtc rule as well.

We are, quite intentionally. I should have spelled it out in the -rc1 release notes, but certainly will in the v2013.10 release itself. We've wanted to do these changes for a while (as the rules for invoking dtc got quite complex for handling all the versions) but were able to get a new release out of upstream before changing things around. FWIW, Fedora/related has packages available.

I believe some mention of this limitation in the release note would have been great. Yes, fedora has newer packages available, but ubuntu is still adding 1.4.0 DTC support (to newer versions) and I don't know what are the timelines to back-port it on LTS releases like 12.0.4
Thanks for your help. Regards, Bhupesh

It looks like 1.4.0 was released in Debian a couple of weeks ago:
http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=713991 https://bugs.launchpad.net/ubuntu/+source/device-tree-compiler/+bug/1194183
Can we sync this to Ubuntu before feature freeze? It looks like libfdt1 is used by qemu, so we just need to take care not to break anything.
This won't help with 12.04 without a separate backport, but at least we'll have it in Saucy as a start.
Serge: thoughts?
