bug in yocto - compiler bug in STM32MP1-Ecosystem-v5.0.0 mickledore-mp1-v23.06.21

[UStre.2]

Hi,

compiler bug while building m4-projects from `https://github.com/STMicroelectronics/oe-manifest/tree/mickledore` The compiler series 11.2 has a internal compiler bug, so that I cannot compile the yocto mickledore with st settings. 
The issue is here `https://github.com/STMicroelectronics/meta-st-stm32mp/blob/mickledore/recipes-devtools/gcc-arm-none-eabi/gcc-arm-none-eabi_11.inc` - buggy compiler is used.

Here are some bug reports on this topic:

Here the answer from arm:

Dear Bernard,

Thanks for your feedback.

Sorry for my ignorance, but I don't see directly how this is linked with the file you attached earlier in the conversation.

Wasn't the file something I needed to use?

In the code above I see recipes for the devtools, which seems to be related to the Yocto builds.

Is Yocto downloading and building GCC ARM ?

So fixing the recipe would fix the build?

Thanks in advance for the clarifications.

Stefan.

@debugging, These wiki articles are generic ones ("how to's"). The issue here comes from Arm gcc toolchain version and the patch (consisting in moving to another arm gcc toolchain version) will be integrated in V5.0.1 version delivered today.

But it is a good point, not easy to solve, how to share with customers already known issues ... any proposal ?

[Bernard PUEL]

Hello Stefan,

Yes this is the same patch already shared in zip. You need to apply it in Yocto bsp layer (you can use git am or git apply-patch for that) : openstlinux-6.1-yocto-mickledore-mp1-v23.06.21/layers/meta-st/meta-st-stm32mp.

The patch will change arm gcc version used to build the M4 SW then resolving the reported build issue.

Hope it is clear.

[Stefan77]

Dear Bernard,

I looked into it further this morning and applied the changes to the recipe.

Running again "bitbake st-image-weston".

I saw the recipe for the devtools got executed (which I wasn't sure would be the case) and now the earlier task seems to pass. At least the build is still running.

Thanks for the help and clarifications.

Regarding @debugging's remark for documentation. The issues should probably be on git, or alternatively a pinned thread on the forum. But the documentation should have a link to that list.

Other problems are most probably to be expected given the complexity of the build chain and the great variety or Linux package flavors.

[debugging]

Hello Bernard, about ideas. Don't want to interfere this discussion  So Ill probably create one for it to that other can provide input as well.

[Stefan77]

Dear Bernard,

I just wanted to report that the build finished without further issues and I was able to flash the created image to my DK1.

Thanks for the help.

[Bernard PUEL]

Happy to see your pb solved Stefan. This patch is integrated in release V5.0.1 that was delivered today.
