  i used something like this once upon a time, can't remember where i
wrote it up, but i asked about it in some detail back here:

https://lists.yoctoproject.org/pipermail/yocto/2016-March/028923.html

perhaps someone can verify if i made any sense back then.

Right, so the problem for me is that there seems to be two ways to do this:

MACHINEOVERRIDES .= ":machine3" (for 3a, 3b)

or

FILESEXTRAPATHS_append_machine3a = "${THISDIR}/files/machine3/"
FILESEXTRAPATHS_append_machine3b = "${THISDIR}/files/machine3/"

But it's not clear to me which is better or fits with the philosophy of
yocto/bitbake.

  isn't this precisely what MACHINEOVERRIDES is for?

Extend FILESEXTRAPATHS using machine-overrides to add common groupings?

Re: [yocto] Can SRC_URI look in the same place for two different machines?

[Giordon Stark]

Hi,

I would do that, but what I want to do is something like this:

Machine1
Machine2
Machine3a
Machine3b
Machine4

I want 3a/3b to have some shared dtsi files, but these should not be shared
with machines 1, 2, 4. I'm not sure it's just a matter of placing it under
files/ because I don't want those picked up by the non-3 machines.

Can't you just put common files in files/file.dtsi and then the
machine-specific ones in files/[machine]/?

[yocto] Can SRC_URI look in the same place for two different machines?

[Giordon Stark]

Hi,

So for my device trees, I'm finding some files are duplicated. In
particular some of my dtsi files are going to be the same amongst a few
boards we're using, so I would like to have each machine name distinct so
that

FILESEXTRAPATHS_prepend := "${THISDIR}/files:"

files/${MACHINE}/${MACHINE}.dts

is picked up, while still having

files/common/*.dtsi picked up as well. As an example of my SRC_URI appends:

SRC_URI_append_gfex-prototype1b = " \
file://skeleton.dtsi  \
file://pl.dtsi\
file://zynq-7000.dtsi \
file://system.dts \
"

SRC_URI_append_gfex-prototype2  = " \
file://skeleton.dtsi   \
file://pl.dtsi \
file://zynq-7000.dtsi  \
file://system.dts  \
"

I suspect I do something with OVERRIDES in the conf/machine/${MACHINE}.conf
file but not sure...

Thanks,

Giordon
