Hi all,

Intel and WR YP QA is planning for QA execution for YP build yocto-3.1.12.rc1. We are planning to execute following tests for this cycle:

OEQA-manual tests for following module:
1. OE-Core
2. BSP-hw

Runtime auto test for following platforms:
1. MinnowTurbot 32-bit
2. Coffee Lake
3. NUC 7
4. NUC 6
5. Edgerouter
6. Beaglebone

ETA for completion next Tuesday, Nov 23.

Thanks,
Jay

hi sir,

i am working on yocto ,i created one core-image-base inside that image i want to set logo on u-boot and kernel side ,i added psplash also in local.conf (IMAGE_FEATURES = "psplash")  .
but default logo even not coming please tell how set splash screen logo in yocto side, bellow error i got it will be helpfull for u.

thanks in advance

Hi Khem,

Patching piece below looks quite a bit.
lets just fix v5.14.14 and dont worry about 3.4

v5.14.14 is already fixed. The only release currently is 3.4 and I hit
that issue, hence the patch.
I assume not everybody is updating to 3.4.1 when it's out, I've seen
people running behind dot releases.
What's bothering you?

once dot release is out then thats whats maintained not the original
release since they are incremental.
the anon python to apply a patch. Can you explain why we want to patch
applied this way ?

I could define a python function and use it like this:
SRC_URI:append:rk3399 = "${@rk3399_fix_mac(d)}"

Would that work better for you?

I am not yet convinced why should we have such version specific patch

If you could explain what's *really* bothering you, I could try to find a proper explanation or agree with you but it's a bit too vague to me right now. Anyway, I'll do some guesses in the next paragraphs.

Because Ethernet does not work for all RK3399-based boards in the latest and only release of Honister?

meta-rockchip does not have honister branch for now. So it expects
master to keep working with honister for now. kernel upgrades are
already committed into honister branch on meta-yocto-bsps so fix it
already available in latest honister
branch and will be in imminent point release soon as well.

meta-rockchip does not have a honister branch for now because it is
still working with master branch from OE-Core. This patch does not break
this behaviour.

meta-rockchip is the BSP layer for Rockchip based devices, if not there, where should I put this patch?

Or are we just going to say "Ethernet does not work, we know" to people asking instead of having this patch in? Obviously you could tell them to upgrade their oe-core/poky git repo to rolling honister or 3.4.1 once it's out but having this patch in avoid those questions.

I would say yes, document it as that of a known issue and possible fix

Do I add a "known issues" to the README then? Or where am I supposed to
add this piece of information were this patch not merged?

if someone is using exact point release. They might have snapshotted
meta-rockpi too and in that case it will be easy for them to carry a
local patch if needed.
vesion specific patching would also be setting a not so desired
patching practice, so I am trying to avoid it if we can.

I think we both understand each other's stance and I've no additional
arguments to give, so it'll be up to the maintainer(s) which is
officially Trevor, but maybe I am not aware of other unofficial
maintainers :)

In any case, I can have this patch in my own vendor BSP but since it
applies to all RK3399-based devices, I thought it'd be nicer to have it
in upstream meta-rockchip than in a vendor BSP unrelated to the boards
one's using.

@Trevor/maintainers, let us know what's your opinion on this so I know
if I should send a v2 using inline python function for SRC_URI instead
of using the anonymous python function.

Cheers,
Quentin

I understand we're talking about policy here. I am not fond of this patch either but Ethernet is quite critical on boards which don't have WiFi for example. I don't have anything better to suggest to fix this in the *latest* release.

Update to latest honister branch or wait for 3.4.1, would be my suggestion.

+
+Commit 2d26f6e39afb ("net: stmmac: dwmac-rk: fix unbalanced pm_runtime_enable warnings")
+while getting rid of a runtime PM warning ended up breaking ethernet
+on rk3399 based devices. By dropping an extra reference to the device,
+the commit ends up enabling suspend / resume of the ethernet device -
+which appears to be broken.
+
+While the issue with runtime pm is being investigated, partially
+revert commit 2d26f6e39afb to restore the network on rk3399.

Are you working with Yocto builds? Do you need to understand what licenses you have? Do you need to understand what changed between two builds/releases/versions?

I know the pain. License manifest will contain everything you need, but it is not in a very easily consumable format, especially the changes.

Pelion has today released an open source tool that allows you to quickly convert the Yocto's license manifest file into:
- a CSV file
- an Excel file (with pivot table)

and by giving the tool two different manifest files - a change summary (again in .CSV and .xlsx-format).

https://github.com/PelionIoT/licensetool

Our small thanks to the Yocto project. I hope others will find this tool useful.

Best Regards,


Janne Kiiskilä

From Linux kernel v5.14 to v5.14.11 (both included), the Ethernet MAC
controller found on RK3399 is not working.

A fix is available in v5.14.12 and later (available also in v5.15)
which is provided here and applied to linux-yocto source tree if
linux-yocto version is of the impacted ones.

The conditional patching is unfortunately required because Honister 3.4
has linux-yocto v5.14.9 and Honister 3.4.1 will have at least
linux-yocto v5.14.14.

+Subject: [PATCH] net: stmmac: dwmac-rk: Fix ethernet on rk3399 based devices
+
+[ Upstream commit aec3f415f7244b7747a7952596971adb0df2f568 ]
+
+Commit 2d26f6e39afb ("net: stmmac: dwmac-rk: fix unbalanced pm_runtime_enable warnings")
+while getting rid of a runtime PM warning ended up breaking ethernet
+on rk3399 based devices. By dropping an extra reference to the device,
+the commit ends up enabling suspend / resume of the ethernet device -
+which appears to be broken.
+
+While the issue with runtime pm is being investigated, partially
+revert commit 2d26f6e39afb to restore the network on rk3399.
+

2.30.2

Hi,

I am facing the same problem right now. I have created some new variables e.g., INTERNAL_VARIABLE, added them to BB_ENV_EXTRAWHITE, and in some recipes, I expect that some tasks are executed again, when I change these variables
e.g., do_install[vardeps] = "INTERNAL_VARIABLE"

I have two possible values for this variable. When I set the variable for the first time, everything works and there is no problem, the do_install will run when I change from one value to another. However, if I set the variable again to the old value, and I execite "bitbake recipename" again, this does not work, and this leads to some wrong/old data located in work directory, and also produced in the image.

I tried setting BB_DONT_CACHE, but this did not work at all.

I do not want to always run the tasks i.e., do_install[[nostamp] = "1", I just want it to run again every time I change this INTERNAL_VARIABLE.

Is what I am expecting a normal behavior? Or Yocto does not work this way?

Regards,
Mohannad

This adds a recipe for building the lvgl sample from mainline zephyr
source. We need to include one upstream patch that fixes a build problem
with lvgl and pull in two other modules or otherwise the default config
will fail to build. Currently only the nordic reference devkit for
nrf52840 is supported.

Big thanks to Eilís Ní Fhlannagáin <elizabeth.flanagan@...> for
helping me with that.

+Subject: [PATCH] cmake: added missing file ext to
+ lv_font_dejavu_16_persian_hebrew.c
+
+CMake >= 3.20 requires file extensions explicitly added to source files.
+
+See CMP0115:
+> Starting in CMake 3.20, CMake prefers all source files to have their
+> extensions explicitly listed:
+
+In the CMakeLists.txt, the file lv_font_dejavu_16_persian_hebrew.c
+was added without its .c extension, causing never CMakes ti fail
+discovering the file.
+
+This has been fixed by correctly add the file as:
+lv_font_dejavu_16_persian_hebrew.c
