[U-Boot] problems with building u-boot-fit-dtb.bin

[Heiko Schocher]

Hello Tom,

I planned to send my patches which convert the imx6 based aristainetos
boards to support DM ... building U-Boot works fine on 2 different build
machines at home, also on 2 build machines in munich @ denx ...

So I startet as usual a travi build and I get:

https://travis-ci.org/hsdenx/u-boot-test/jobs/596917922


arm:  +   aristainetos2b
+make[2]: *** No rule to make target 'u-boot-fit-dtb.bin', needed by 'u-boot-dtb.imx'.  Stop.
+make[1]: *** [u-boot-dtb.imx] Error 2
+make: *** [sub-make] Error 2

(for all aristainetos boards)

:-(

Unfortunately I cannot reproduce this on my machines...
(builds with "-j 64" or "-j 1" working fine)

I think it is a timing/sync issue, but how to debug ?

Checked make versions:

make on one of my build machines:

pollux:~ hs $ make --version

pollux:~ hs $ cd abb/mainlining/u-boot
pollux:u-boot

make on travis:

Ok, for faster "debugging travis" I removed all other jobs from the
travis file and started build again:

https://travis-ci.org/hsdenx/u-boot-test/builds/597504777

The error for the aristainetos boards are gone .... ?!?!?
(Ok, there are others, but not related to my changes)

I think it has to do with the config options:

CONFIG_OF_CONTROL=y
CONFIG_DEFAULT_DEVICE_TREE="imx6dl-aristainetos2_4"
CONFIG_OF_LIST="imx6dl-aristainetos2_4 imx6dl-aristainetos2_7"
CONFIG_DTB_RESELECT=y
CONFIG_MULTI_DTB_FIT=y

and I can only find mips boards, which has this settings. Difference
for imx boards to mips Makefile is, imx has make target in 2 Makefiles:

Makefile
arch/arm/mach-imx/Makefile

So the "u-boot-fit-dtb.bin" target is definitely there ...

Any ideas?

bye,
Heiko
