Hi, this is not a direct yocto question, but more a question about embedded systems in general. If you have a suggestion on where to ask, please forward me. How do you normally handle user removable storage in you embedded linux systems? How do you make sure that it is safe to remove the storage at any point in time without corrupting anything (unless something is actually writing to the card
<BoJalling>
at that point in time). Do you mount and unmount everytime you need to write to the storage?

Hi everyone. I hope someone can help me understand what I am doing wrong in yocto build.
<MathiasKoch[m]>
I have a fairly simple project based primarily around meta_raspberrypi, but attempting to build for a custom board using a CM3. Thus I need a custom virtual/kernel, that i have added in a separate layer (meta-revpi/recipes-kernel/linux-kunbus). All is great so far, it compiles and runs as expected.

My trouble comes as soon as I am trying to use any sort of custom defconfig/kernel config/fragments. They just don'

BoJalling: You probably should adapt your software for unmounting in that it should not keep open filedescriptors if not actively using them.

how can i update the /boot/config.txt ona running yocto raspi 4 ?

not in yocto but during runtime, actually the is no such file in /boot

hi, i added "dtparam=ant2" to "RPI_EXTRA_CONFIG" for activate the external antenna in meta-raspberrypi(dunfell). when i check with "cat /sys/kernel/debug/gpio" command, i can't see the relevant pin as high. but i can see it in kirkstone.

Hey guys, can you confirm that inheriting systemd does not mean that systemd gets added to DEPENDS?
zpfvo has joined #yocto
<qschulz>
ptsneves: 1) read the systemd.bbclass and the classes it inherits 2) verify with bitbake-getvar DEPENDS -r recipe
<ptsneves>
qschulz: I did exactly that and did not find systemd added to the DEPENDS. That is very surprising
<ptsneves>
I guess one thing is systemd runtime file setup. Another is libsystemd
<Saur[m]>
ptsneves: The `systemd` bbclass is for unit file support. It does not imply a build dependency on `systemd`, which is good as it is often not needed..
<ptsneves>
Saur[m]: Today I learned!
<ptsneves>
I am happy that my diagnostic thought process was the same as @qschulz

moto-timo: nope. it means that at the moment python3-wheel-native installs just .py files because previously it didn't install .pyc files, but the sysroot contained .pyc files as they got generated on use. so now we can't install .pyc files as they'll conflict with existing untracked files and sysroot unpack explodes.
<moto-timo>
rburton: ok. keep it then is what I am hearing ;)
<rburton>
moto-timo: so we either need a way of doing extra cleanup to wipe out the .pyc files, or let sstate write over untracked files, or wait for a tmpdir version bump and at the same time remove that line.
<rburton>
yes, keep it for now :)

how come bitbake uses a string as a 'queue' in poky/bitbake/bin/bitbake-worker? i tried a multiconfig with like 9 machines, and the whole thing seems very slow..

is there a recommended practice for having continuous integration populate an SSTATE_MIRRORS location, or is it as simple as configuring the CI build to use that destination for its SSTATE_CACHE dir?

mischief: i guess that makes more sense, too. if a build fails, then the public mirror isn't touched. thanks
yssh has quit [Ping timeout: 260 seconds]

but the end result is just a straight copy, there's no massaging before it's made public?

well, our build and sstate is not public, but yes

"more public than local to the build agent" :)

our setup is rather convoluted, but i'm the only one who wears the build system hat, so /shrug
<zelgomer>
historically i am not a build system guy, suddenly thrust into a build system role, so here i am asking stupid questions :)
<mischief>
one jenkins instance runs bitbake inside of two ECS nodes in ec2, so they both upload to and read from the same sstate mirror in s3
<mischief>
in the future it might be converted to EFS to skip the need for a separate upload step
<mischief>
(EFS is just nfs)

i see. mine is nfs

I did this in my bb file DEPENDS += "libssl10" but I am getting "Nothing PROVIDES 'libssl10'" How to add that?
amitk_ has quit [Ping timeout: 246 seconds]
<khem>
is there libssl10 recipe ( bb ) somewhere in your workspace ?
<khem>
DEPENDS is a build time dependency and need to be either a recipe name or a PROVIDES name from some recipe which might alias somewhere
<dash_hope>
rburton: actually we had issue and when we installed libssl1.0-dev (we need this specific version) on the host it fixed the problem. However, I think we shouldn't depend on HOST environment. So, want to see if openssl_3.02 will fix the problem using DEPENDS.

https://git.openwrt.org/?p=openwrt/openwrt.git;a=commitdiff;h=d0501dc7fc078fb9e91d5365474db9ed8200f9e0 --someone also had the same issue. I fixed this by installing libssl-dev in ubuntu. However certificate signing is failing because we need libssl1.0-dev but if i install this then i see other issues. So want yocto to provide libssl1.0-dev.
<rburton>
the important bit was "i'm trying to build tf-a" and a log of what the error is, then we know that you actually want a native openssl not the target one. its important to explain what you're trying to actually do, not just what you think the solution is.
