Hi, I’m attempting to integrate Mender client into our Yocto Zeus build for a custom iMX6ULL board. Our source for u-boot is set up for EXTERNAL\_SRC, so I have to do the manual patching via
```auto
```
The resulting patchfile (pasted below) seems to be missing the Mender env variables (`mender_setup`, `mender_saveenv_canary`, etc.) that are mentioned in this post:
[https://hub.mender.io/t/beaglebone-missing-default-u-boot-environment-in-mmc/1505/6](https://hub.mender.io/t/beaglebone-missing-default-u-boot-environment-in-mmc/1505/6)
Should these variables still be added to u-boot env?
Thanks,
Stu

Hi @sjuengst,
You seem to be missing [this patch](https://github.com/mendersoftware/meta-mender/blob/master/meta-mender-core/recipes-bsp/u-boot/patches/0002-Generic-boot-code-for-Mender.patch). If our docs are missing a step please let me know.

I see 4 Mender-provided patches in `build/tmp/work/hermes-poky-linux-gnueabi/u-boot-imx/1_2020.04-r4`

I assumed that `bitbake -c save_mender_auto_configured_patch u-boot ` would consolidate them into `mender_auto_configured.patch`. Do I have to apply them manually myself and then do `save_auto_configured_patch`?
Thanks,
Stu

I had MENDER\_UBOOT\_AUTO\_CONFIGURE set to “0” when I first ran `save_mender_auto_configured_patch`. It occurred to me that maybe it should be ‘1’ for generating the patch and then turned off afterwards (the docs don’t say which setting to use). I tried regenerating the patch with MENDER\_UBOOT\_AUTO\_CONFIGURE = “1” and ran into another problem. It seems that the do\_configure\_append() in my u-boot-imx\_2020.04.bbappend is not being executed when I run `save_mender_auto_configured_patch` (none of my board-specific files, \_defconfig, etc. are being installed) so the build fails.

I had worked around this the first time around by changing `MACHINE` to `imx6ull14x14evk` (which doesn’t require a do\_configure\_append), but this was unsatisfactory because the evk and hermes defconfigs are different enough to cause the patch to fail. I had to manually clean it up.
Thanks,
Stu

I fixed the build failure by changing my .bbappend to install my hermes board-specific files in do\_mender\_uboot\_auto\_configure\_prepend() instead of do\_configure\_append(), but I’m still missing the 0001- through 0004- Mender-supplied patches even when MENDER\_UBOOT\_AUTO\_CONFIGURE=“1”. So I’m back to the question of whether I’m supposed to apply them manually myself or should they be included in `mender_auto_configured.patch`?
Thanks,
Stu

They should not be included in `mender_auto_configured.patch`. Aren’t they listed in your `SRC_URI`? It can be checked with `bitbake -e u-boot-imx` and then grepping for it.

Getting back to this after some time away. I’ve added
```auto
SRC_URI += "file://0001-Add-missing-header-which-fails-on-recent-GCC.patch"
SRC_URI += "file://0002-Generic-boot-code-for-Mender.patch"
SRC_URI += "file://0003-Integration-of-Mender-boot-code-into-U-Boot.patch"
```
to my u-boot-imx\_2020.04.bbappend but I don’t see bitbake running the do\_patch() task for u-boot-imx and the patches are not being applied. What am I missing?

Hi @sjuengst what file did you add those settings in? Can you share the output from `bitbake -e virtual/bootloader`?

I’m adding the patches to the u-boot-imx\_2020.04.bbappend in our board’s new layer. The output of bitbake -e virtual/bootloader is too long to post here. Is there a particular section of interest?

It actually looks like those patches are included 3 times (and does it matter that there are no newlines between them at the end?).

You don’t seem to have a git repo in the SRC\_URI definition. My best guess is you have something that is overwriting SRC\_URI rather than appending to it.
Specifically I’d look at these bits:
```
# set /yocto-src/sources/meta-imx/meta-bsp/recipes-bsp/u-boot/u-boot-common.inc:13
# "git://git.denx.de/u-boot.git"
# set /yocto-src/sources/meta-imx/meta-bsp/recipes-bsp/u-boot/u-boot-imx_2020.04.bb:20
# "${UBOOT_SRC};branch=${SRCBRANCH} "
```

Our u-boot-imx repo is EXTERNALSRC. I wonder if that is causing the denx and NXP additions to SRC\_URI to be removed. Other than that, I can’t find any place where SRC\_URI is set rather than appended.

Honestly I have never tried EXTERNALSRC and I don’t know if patches will be automatically applied in that case. Can you add them manually to your external source checkout?

Yes, I had actually done this earlier but then decided it would be better to patch it live. I can revert to a pre-patched repo.

Please let us know if that works. I’m definitely curious to know if patch files in SRC\_URI work with EXTERNALSRC setups.

Yes, applying the patches manually to external source successfully worked around the issue. Thanks!
