Subject: [Buildroot] [PATCH 1/1] boot/uboot: Really use host-dtc
Date: Thu, 26 Jul 2018 12:36:30 +0200	[thread overview]
Message-ID: <20180726103630.8643-2-david.degrave@mind.be> (raw)
In-Reply-To: <20180726103630.8643-1-david.degrave@mind.be>

U-Boot's build system (at least in 2018.01) does not use $(HOST_DIR)/bin/dtc to
compile dts files. Instead it tries to use it's internal dtc who is not
compiled by default and result in a build failure:

  DTC     arch/arm/dts/foo.dtb
/bin/sh: ./scripts/dtc/dtc: No such file or directory
make[4]: *** [scripts/Makefile.lib:329: arch/arm/dts/foo.dtb] Error 127

To reproduce this error, use a uboot config that contains the following:

CONFIG_MULTI_DTB_FIT=y
CONFIG_OF_LIST="foo"
