friend recently asked me for recommendations for entry-level,
linux-based drones whose software is generated by yocto project, so it
could be used as a learning experience. as in, the fun would be in
the creation and customization of the software, not just playing with
the drone.

i didn't have an immediate answer ... i recall that qualcomm has
linux-based drone components:

https://developer.qualcomm.com/hardware/qualcomm-flight-pro

and i'm aware of https://www.dronecode.org/, focused on OSS drone
projects.

any thoughts on linux-based drones where one would build the
software using yocto project?

Hello,

The execution of "make scripts prepare" did actually solve the issue, thank you very much for your help!

However, the need to manually execute this command on the target platform made me look into the kernel-devsrc recipe (https://git.yoctoproject.org/cgit/cgit.cgi/poky/tree/meta/recipes-kernel/linux/kernel-devsrc.bb?h=zeus) to see if it is possible to let the build host execute this step. Some comments imply that this is the case. Consider, for instance, the one in line 257:

Ensure we don't race against "make scripts" during cpio

Unfortunately, I was unable to figure out how to do this. Is there a way to let the recipe trigger this step automatically?

Thanks!

Paul,
Thanks for the reply.
I am using Xilinx-SDK based : Linux version 4.19.0-rt1-xilinx-v2019.1

Can you please let me know how to verify the yocto version running on
target.

You might have better luck on the meta-xilinx mailing list. They should
know the details for their BSP.

More info on Xilnx layers and a pointer to subscribe info to the mailing
list is here:

Yocto Project doesn't have a version "2019.1", see
https://wiki.yoctoproject.org/wiki/Releases.

I guess you're using a vendor supplied BSP or SDK with that version
number. Could you provide the Yocto Project version number and the
layers in use, or at least give some more info on where your "2019.1"
release is from.

Thanks,

Hello everyone,

I am using the Yocto-based build system provided by NXP (primarily via the meta-freescale layer) to create Linux images for an i.MX 8M board and would like to develop small kernel modules without going through the build process of the entire image after each modification. Therefore, I would prefer to compile the kernel modules on the target architecture and have added the following items to the IMAGE_INSTALL variable via my local.conf:
 - packagegroup-core-buildessential

I then tried to follow the the official build instructions (https://www.kernel.org/doc/html/latest/kbuild/modules.html) on the target but was unable to create a kernel module:

Hi,

You need to run "make scripts prepare" in /usr/src/kernel before trying to compile kernel modules on target.

What am I missing here? Is there something else I have to do on the target before I can compile kernel modules on the target?

For the sake of completeness: The build is based on the Zeus release and the following repo manifest file:
https://source.codeaurora.org/external/imx/imx-manifest/tree/imx-5.4.47-2.2.0.xml?h=imx-linux-zeus

Thanks!

One more thing: I tried reverting the linux-libc-headers version change (57d5f4ad410d4e9d55bdd9734bf5ab8fa6667a53) and that fails in the same way, so it's not that.

I also realized that the yocto-3.2 tag does not include the 3.2.1 updates; however the same issue happens on 3.2.1 as well.

I will try to bisect this but it seems like it will take a long time since I need to wipe the tmp directory at every step.

Hi,

I hit the same issue, also while trying things out on WSL2 (not committed enough to build a dedicated workstation/VM). I found a few more things:

This seems to be a pseudo abort with:

path mismatch [2 links]: ino 409763 db '/run/shm/sem.mp-bzdlrxrj' req '/run/shm/tGpqeT'.

I tried to follow the instructions to collect as many logs as possible. Logs are attached as far as I could find them; the strace is too big and you can find it here.

This is a regression: poky-3.1 (which uses linux-libc-headers 5.4) works. It seems we are not the only ones with this issue, and others have already given up on Yocto-on-WSL2.

Hope this is useful,
Matthias

i'm not fluent enough in ruby to want to submit a patch for this, so
i'll let someone higher up the food chain handle it.

trying to build a number of "native" ruby recipes from
meta-openstack, and getting precisely the same error for various
recipes:

| ERROR: Gemspec file not found: XXXXX-native.gemspec.gemspec

the clear bug here is that something is adding a ".gemspec" suffix to
a string that *already* has that suffix. that error is acknowledged
here ("Append '.gemspec' extension only when it is not present"):

https://github.com/voxik/rubygems/commit/6c3f0dc798966a6474f6d694da05a15d620760d6

so someone who is more comfortable with ruby is invited to deal with
that.

rday

to prepare for trying to build a number of ruby gems for WR LTS19
(effectively zeus, as always), i thought i'd start simple and begin
with building for qemux86-64 with gatesgarth so i could plausibly
claim that i have a working basis for comparison, whereupon if that
worked for what i was after, i could work backwards.

i just now started a build for qemux86-64/gatesgarth with "bitbake
ruby", and i'll take it from there. knowing little about ruby, is
there a smaller community that would help with issues i run into, or
should i keep the discussion here?

i want to start by trying to build absolutely stock puppet and chef,
and if that turns out to need fixing, i will of course submit patches.
if anyone has already gone through this exercise, that would be just
ducky.

i should have the result of the first build in an hour or two --
given that i'm not trying to do anything out of the ordinary, i would
*hope* that a totally generic build would work out of the box, but
we'll see.

rday

p.s. the above recipes involve the layers meta-cloud-services and
sub-layer meta-openstack.

We encountered a runtime error for auditctl on lib32 image for aarch64:

root@qemuarm64:~# auditctl -a always,exit -F arch=b32 -S adjtimex -S settimeofday -k time_change
arch elf mapping not found

The root cause is the aarch64 processor support is not enabled for arm
build. Refer to Debian[1] and Fedora[2], actually we can enable
arm/aarch64 processor support unconditionally.

Dear Team,

I'm using yocto dunfell version 3.1.3 .  in my image ipv6 configuration is coming, which I don't need. I need to disable it completely.

Please assist me the correct way to do the same.

Thanks.

The yocto-3.2.1 and gatesgarth-24.0.1 tags for meta-gplv2 have been
incorrectly
set on the dunfell branch rather than the gatesgarth branch. The Git
revision
and tar balls below are correct though. Since the tags are signed I
do now want
to modify them myself, so please correct them as soon as possible.

Vineela isn't working this week I think so she might not be able to

Hi folks,

Working on the docs recently we noticed that there is no automatic
addition of a trailing slash on layers.openembedded.org when it's
needed:

https://layers.openembedded.org/layerindex/branch/master/layer/openembedded-core
- shows "Page not found".

https://layers.openembedded.org/layerindex/branch/master/layer/openembedded-core/
- shows the layer correctly.

Is this something that can easily be fixed?
